TL;DR: In this paper, the authors developed 177 heat-responsive gene-based SSRs from wheat genome for assessing genetic diversity analysis of thirty-six contrasting wheat genotypes for heat tolerance, of which 144 yielded unambiguous and repeatable amplicons, however, thirty-seven were found polymorphic among the 36 wheat genotype.
Abstract: Being a major staple food crop of the world, wheat provides nutritional food security to the global populations. Heat stress is a major abiotic stress that adversely affects wheat production throughout the world including Indo-Gangatic Plains (IGP) where four wheat growing countries viz., India, Bangladesh, Nepal and Pakistan produce 42% of the total wheat production. Therefore, identification of heat stress responsive molecular markers is imperative to marker assisted breeding programs. Information about trait specific gene based SSRs is available but there is lack of information on SSRs from non-coding regions. In the present study, we developed 177 heat-responsive gene-based SSRs (cg-SSR) and MIR gene-based SSR (miRNA-SSR) markers from wheat genome for assessing genetic diversity analysis of thirty- six contrasting wheat genotypes for heat tolerance. Of the 177 SSR loci, 144 yielded unambiguous and repeatable amplicons, however, thirty-seven were found polymorphic among the 36 wheat genotypes. The polymorphism information content (PIC) of primers used in this study ranged from 0.03–0.73, with a mean of 0.35. Number of alleles produced per primer varied from 2 to 6, with a mean of 2.58. The UPGMA dendrogram analysis grouped all wheat genotypes into four clusters. The markers developed in this study has potential application in the MAS based breeding programs for developing heat tolerant wheat cultivars and genetic diversity analysis of wheat germplasm. Identification of noncoding region based SSRs will be fruitful for identification of trait specific wheat germplasm.

TL;DR: In this paper, the antibacterial potential of ZnO NPs against E. coli from faeces samples was carried out by using 16-23s rRNA primers, and the results of the physico-chemical characterization revealed that the biosynthesized nanoparticles were of 93.7% purity with an average size between 45 and 50nm.
Abstract: The current study was undertaken to investigate the antibacterial (against molecular characterized E. coli isolated from poultry faeces) potential of biosynthesized zinc oxide nanoparticles (ZnO-NPs) from Passiflora subpeltata Ortega aqueous leaf extract. The biosynthesized nanoparticles were subjected to physico-chemical characterization to study shape, size and purity by UV–Vis spectroscopy, X-Ray diffraction (XRD), Fourier Transform Infrared Spectroscopy (FT-IR), Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS) and Transmission Electron Microscopy (TEM). The molecular identification of isolated E. coli from faeces samples was carried out by using 16–23s rRNA primers. The results of the physico-chemical characterization revealed that the biosynthesized nanoparticles were of 93.7% purity with an average size between 45 and 50 nm. The ZnO-NPs offered significant inhibition against the isolated Gram-negative E. coli with MIC at 62.5 µg mL−1 concentration. The antibacterial potential of ZnO NPs against E. coli has also been investigated by the cell viability test, and further the effects of ZnO NPs on bacterial morphological structures was analysed by SEM and TEM.

TL;DR: In this paper, the authors mined 171 salt-responsive genes (including 10 miRNAs) from bread wheat genome using the sequence information of functionally validated salt responsive rice genes and validated among the contrasting panels of 54 tolerant as well as susceptible wheat genotypes.
Abstract: Salt stress adversely affects the global wheat production and productivity. To improve salinity tolerance of crops, identification of robust molecular markers is highly imperative for development of salt-tolerant cultivars to mimic yield losses under saline conditions. In this study, we mined 171 salt-responsive genes (including 10 miRNAs) from bread wheat genome using the sequence information of functionally validated salt-responsive rice genes. Salt-stress, tissue and developmental stage-specific expression analysis of RNA-seq datasets revealed the constitutive as well as the inductive response of salt-responsive genes in different tissues of wheat. Fifty-four genotypes were phenotyped for salt stress tolerance. The stress tolerance index of the genotypes ranged from 0.30 to 3.18. In order to understand the genetic diversity, candidate gene based SSRs (cg-SSRs) and MIR gene based SSRs (miR-SSRs) were mined from 171 members of salt-responsive genes of wheat and validated among the contrasting panels of 54 tolerant as well as susceptible wheat genotypes. Among 53 SSR markers screened, 10 cg-SSRs and 8 miR-SSRs were found to be polymorphic. Polymorphic information content between the wheat genotypes ranged from 0.07 to 0.67, indicating the extant of wide genetic variation among the salt tolerant and susceptible genotypes at the DNA level. The genetic diversity analysis based on the allelic data grouped the wheat genotypes into three separate clusters of which single group encompassing most of the salt susceptible genotypes and two of them containing salt tolerance and moderately salt tolerance wheat genotypes were in congruence with penotypic data. Our study showed that both salt-responsive genes and miRNAs based SSRs were more diverse and can be effectively used for diversity analysis. This study reports the first extensive survey on genome-wide analysis, identification, development and validation of salt-responsive cg-SSRs and miR-SSRs in wheat. The information generated in the present study on genetic divergence among genotypes having a differential response to salt will help in the selection of suitable lines as parents for developing salt tolerant cultivars in wheat.

TL;DR: In this paper, two Ras-related nuclear protein (Ran) genes TaRAN1 and TARAN2 were identified though genome-wide analysis in wheat (T. aestivum).
Abstract: Maintenance of growth is important for sustaining yield under stress conditions. Hence, identification of genes involved in cell division and growth under abiotic stress is utmost important. Ras-related nuclear protein (Ran) is a small GTPase required for nucleocytoplasmic transport, mitotic progression, and nuclear envelope assembly in plants. In the present study, two Ran GTPase genes TaRAN1 and TaRAN2 were identified though genome-wide analysis in wheat (T. aestivum). Comparative analysis of Ran GTPases from wheat, barley, rice, maize, sorghum, and Arabidopsis revealed similar gene structure within phylogenetic clades and highly conserved protein structure. Expression analysis from expVIP platform showed ubiquitous expression of TaRAN genes across tissues and developmental stages. Under biotic and abiotic stresses, TaRAN1 expression was largely unaltered, while TaRAN2 showed stress specific response. In qRT-PCR analysis, TaRAN1 showed significantly higher expression as compared to TaRAN2 in shoot and root at seedling, vegetative, and reproductive stages. During progressive drought stress, TaRAN1 and TaRAN2 expression increase during early stress and restored to control level expression at higher stress levels in shoot. The steady-state level of transcripts was maintained to that of control in roots under drought stress. Under cold stress, expression of both the TaRAN genes decreased significantly at 3 h and became similar to control at 6 h in shoots, while salt stress significantly reduced the expression of TaRAN genes in shoots. The analysis suggests differential regulation of TaRAN genes under developmental stages and abiotic stresses. Delineating the molecular functions of Ran GTPases will help unravel the mechanism of stress induced growth inhibition in wheat.

TL;DR: In this paper, the influence of climate model biases in the predictions of yield and water requirement of cassava in one of the major cassava growing regions in India was assessed, where simple linear bias correction methods were used for temperature, and non-linear corrections are used for other meteorological variables.
Abstract: The present study is conducted to assess the influence of climate model biases in the predictions of yield and water requirement of cassava in one of the major cassava growing regions in India. Simple linear bias correction methods are used for temperature, and non-linear corrections are used for other meteorological variables. The WOFOST and CROPWAT models are used to predict the crop yield and water requirement of cassava using the scenarios of 2030, 2050, and 2070 for the representative concentration pathway 4.5 derived from the Long Ashton Research Station Weather Generator (LARS-WG). The percentage change in crop yield predictions with and without bias corrections of meteorological variables ranges from 7.6 to 10.8%, 1.6 to 5.4%, and − 3.0 to 4.0% respectively for 2030, 2050, and 2070. The bias corrections made an increment in the gross irrigation requirements of cassava with 16.5, 17.8, and 16.0% in 2030, 2050, and 2070 respectively, compared to the values without bias corrections. The outcome of this study indicates that raw meteorological variables directly from the climate models result over-/underestimation of yield and irrigation requirements of cassava, and the bias corrections help to issue reliable crop yield predictions. Results show zero yield reductions of cassava until 2050, and beyond that, there can be reductions in the crop yield. The gross irrigation requirements of cassava increase in the future to achieve higher productivity. However, this study needs to extend to other major growing regions in India to derive a general conclusion.

TL;DR: Garcinia andamanica King is a tropical fruit bearing species used for a variety of purposes by aboriginal tribes and settler communities of Andaman Islands, India as discussed by the authors, and it was found to be a potential processed product for improving livelihood and nutritional security.
Abstract: Garcinia andamanica King is a tropical fruit bearing species used for a variety of purposes by aboriginal tribes and settler communities of Andaman Islands, India. To explore its potential and promote the cultivation, systematic efforts were initiated so that this genetic resource is sustainably utilized. Studies revealed that in natural habitat, the species grows on soils with pH of 6.1–6.9 and poor to moderate nutrient status. Variations were noticed in morphology, flowering and fruiting characters of the species collected from different islands. Physicochemical analysis suggested acidic nature of the fruit making it suitable for use as acidulant. Fruits were source of carotenoids (0.52–9.47 mg/100 g), phenols (8.35 mg GAE/100 g) and exhibited DPPH scavenging activity (91.33–92.95%). Rind of fruits was dehydrated and it was found to be a potential processed product for improving livelihood and nutritional security. Proximate composition of the dried rind was also determined. Fatty acid analysis of seeds using GC/MS revealed presence of eight compounds. Seeds were rich in unsaturated fatty acids with oleic acid (44.351%) as major constituent and hence, seeds could be used as source of edible oil. Potential threats, regeneration, conservation efforts and activities for promotion of its cultivation have also been discussed. Present is the pioneering attempt in this species on these aspects.

TL;DR: A draft genome of P. erosus is assembled of 460 Mbp in size containing 37,886 gene models and 10,187,899 candidate single nucleotide polymorphisms (SNPs) are identified, reflecting the geographic origin and morphology of the individuals.
Abstract: Yam bean (Pachyrhizus erosus Rich. Ex DC.) is an underutilized leguminous crop which has been used as a food source across central America and Asia. It is adapted to a range of environments and is closely related to major leguminous food crops, offering the potential to understand the genetic basis of environmental adaptation, and it may be used as a source of novel genes and alleles for the improvement of other legumes. Here, we assembled a draft genome of P. erosus of 460 Mbp in size containing 37,886 gene models. We used this assembly to compare three cultivars each of P. erosus and the closely related P. tuberosus and identified 10,187,899 candidate single nucleotide polymorphisms (SNPs). The SNP distribution reflects the geographic origin and morphology of the individuals.

Abstract: The current study focused on determining the potential geographical suitability of cassava and sweet potato, two major tropical root crops of India, using the species distribution model, MaxEnt and QGIS. The model showed excellent performance based on the AUC (area under the ROC curve) values (> 0.8) obtained during training and testing. District wise geographical suitability is analysed, and the results indicate an increase in the geographical suitability of cassava in the future with a percentage increase of 42, 41; 32, 43; and 33, 32 for 2030, 2050, and 2070, respectively, for the two representative concentration pathways (RCPs) 4.5 and 8.5. The same for sweet potato is 32, 25; 27, 31; and 23, 21, respectively. The geographical suitability of rice and potato is also tested in India in the future to compare the results of cassava and sweet potato. The percentage increase in rice suitability is 17, 15; 15, 17; and 13, 11 for 2030, 2050, and 2070, respectively, for the two RCPs about its current growing locations. The increase in geographical suitability of potato is 10, 11; 10, 9; and 10, 9%, respectively. The outcome of this study shares information about the highly suitable districts for cassava, sweet potato, rice, and potato across the Indian subcontinent in the future. It can assist the decision managers in diversifying crops to highly suitable areas to ensure food security.

TL;DR: In this paper, the authors discussed the application of all these approaches for the management of plant pathogens and discussed the potential of genome editing based on engineered nucleases like ZFNs, TALENs and CRISPR/Cas9 to precisely mutate the genomic sequence of interest can be exploited for specific targeting of the host/pathogenic genes associated with the biotic stress response.
Abstract: The ever-increasing demand for food production proportionate to exponential growth of global population evoked the need for applying innovative techniques for developing disease-resistant crop varieties, as the pest and pathogen attack causes considerable yield loss which in turn putts the agriculture sector and crop production in crisis. This is highly significant when the resistance conferred by conventional measures, like artificial hybridization, mutation breeding, marker-assisted selection, etc. appears to be inadequate in many cases, especially due to the evolution of new/more virulent strains/pathovars/isolates of pathogens and their unexpected host range expansion. Development of recombinant DNA technology, transgenic expression and RNA silencing strategies lead to a new era of transgenically engineered resistance in several crop species, many of which succeeded in field trials and got commercialized. Elucidation of genetic and molecular mechanisms underlying host-pathogen interactions, resistance, susceptibility and different levels of plant immune responses (PTI, ETI, HR, etc.) revealed the key genes in the host as well as pathogens that can be manipulated by transgenic approaches/techniques for conferring effective resistance. Reprogramming of phytohormonal regulatory pathways determining defence response and remodeling of molecular receptors/transcription factors involved in resistance or disease development can be brought about by transgenic methods to enhance the resistance in host plants. Targeting of conserved sequences or molecular components could provide broad-spectrum resistance in certain cases. Mining of R genes, transgenic expression of foreign R gene, etc. are other useful strategies. Potential of genome editing based on engineered nucleases like ZFNs, TALENs and CRISPR/Cas9 to precisely mutate the genomic sequence of interest can be exploited for specific targeting of the host/pathogenic genes associated with the biotic stress response. Application of all these approaches for the management of plant pathogens is discussed in this chapter.

TL;DR: F8.IIPR has the potential as a promising biopesticide for controlling the three lepidopteran insects tested and PCR amplification of vip3A gene confirmed its presence in five Bt isolates.
Abstract: Rhizobacterial diversity is an indicator of soil health and in turn it is influenced by the host crops, edaphic factors and weather. The present investigation reports the diversity of endospore forming, gram positive rhizobacteria (Bacillus megaterium, B. thuringiensis, B. cereus and Lysinibacillus spp.) inhabiting 11 different agricultural crops in the IGP of India. Twelve Bacillus thuringensis (Bt) isolates were identified by screening 62 g positive bacterial isolates from 63 rhizosperic soil samples collected from 6 districts of IGP. The highest Bt index was recorded from Bhopal (0.25) followed by Fatehpur (0.17), Kanpur dehat (0.10), Jalaun (0.08) and Hamirpur (0.06). The bacterial isolates were characterized based on the 16SrRNA gene and phylogenetically grouped into 3 clades. The spore crystal mixture of 12 Bt isolates were subjected to insect bioassay and it revealed, F8.IIPR has highest toxicity against Spilosoma obliqua Walker (100%), Olepa ricini Fabricius (91.67%) and Helicoverpa armigera Hubner (100%) larva. Survival analysis (ST50) showed that the S. obliqua is highly susceptible than O. ricini and H. armigera to F8.IIPR. Crystal staining and protein profiling showed the presence of cry 1 (135 kDa) and cry 2 (65 kDa) genes in 5 Bt isolates. PCR amplification of vip3A gene confirmed its presence in five Bt isolates. To conclude F8.IIPR and Ak2.IIPR has the potential as a promising biopesticide for controlling the three lepidopteran insects tested.
TL;DR: In this paper, the authors investigated the uptake pattern and partitioning of nutrients in the total biomass of healthy and root (wilt) diseased palms grown in humid tropical Entisol of Kerala.
Abstract: Nutrient uptake in the biomass of healthy and root (wilt) disease affected coconut palms are different. Root (wilt) is a predominant phytoplasmal disease affecting coconut (Cocos nucifera L.) palms and to sustain the palm health and productivity, better nutrient management practices are required. The objective of this research was to understand the uptake pattern and the partitioning of nutrients in the total biomass of healthy and root (wilt) diseased palms grown in humid tropical Entisol of Kerala. 5 coconut palms each were selected from diseased palms viz., Early (DE), Middle (DM) and Advanced (DA) category along with the control, which is Apparently Healthy palm (AH), without any diseases. The total biomass component with respect to each part viz., leaf (L), petiole (P), spadix (S), spathe (Sp), stem (St), leaf sheath fiber (LSF), husk (H) and nuts (copra:C + shell (Sh)) (N) were estimated. Nutrient uptake by the entire biomass uptake is classified as 1. Recyclable portion (L, P, S, Sp, H, LSF and Sh) 2. Removable portion (C) 3. Reserve biomass (St) and then computed the nutrient partitioning by standard analytical procedures. For all nutrients except Mg, reserve biomass had the greatest nutrient uptake followed by recyclable biomass and removable biomass components. Among the nutrients, potassium recorded the highest total uptake. In AH palm, the total uptake of potassium was 1075 g per palm, whereas it was 407.3 g per palm in the diseased palms. The total uptake of nutrients which showed a significant relation with disease index followed the order K > N > Ca > S > P > Mg in apparently healthy palms and N > K > Ca > S > P > Mg in diseased palms. The percentage reduction in total uptake of N, P, K, Ca, Mg, S and B by diseased palms in comparison with healthy palms was 36.5, 37.6, 57.5, 44.1 23.3, 43.7 and 48.9. The results of the study indicated that the pattern of nutrient uptake in the different biomass components of apparently healthy and root (wilt) disease affected palms are significantly different. This can instigate the formulation of appropriate nutrient management strategies in coconut with emphasis on its residue recycling potential.
TL;DR: In this article, the authors conducted a study to identify the climate resilience of two widely used varieties of cassava in one of the major cassava growing areas in Kerala, India.
Abstract: The present study was conducted to identify the climate resilience of two widely used varieties of cassava in one of the major cassava growing areas in Kerala, India. The future projections for 2030, 2050, and 2070 were derived using the Long Ashton Research Station-Weather Generator (LARS-WG) with integrated global climate models (GCMs). The projections for the representative concentration pathway-4.5 (RCP-4.5) were tested in the crop model, World Food Studies (WOFOST) to assess the resilience of cassava varieties. The future projections in the study region indicated an increase of up to 2.1 and 2.3 °C for maximum and minimum temperatures respectively, followed by solar dimming. The crop yield predictions based on the outputs from the GCMs indicated that the yield of the long duration cassava var. H-226 increased during 2030 from 8.6 to 12% and that of short duration var. Sree Vijaya increased from 3.6 to 5.5%. With the 2050 scenario, the yield increased from 3.3 to 6.7% for var. H-226 and −4.3 to 1.9% for var. Sree Vijaya, respectively. Whereas, during 2070 was a decrease in the yield for vars H-226 and Sree Vijaya ranging from −9 to 3.8% and −10 to −5.2% respectively. The results indicated that var. H-226 is more resilient to the changing climate than var. Sree Vijaya. As an outcome of this study, the var. H-226 can be considered as climate-resilient, and this information can assist the decision makers in selecting an appropriate crop variety to ensure food security.

TL;DR: In this article, a study was conducted to optimize various parameters for efficient Agrobacterium-mediated genetic transformation using embryogenic calli with vectors having gus reporter gene, and the putative transformants were characterized for the integration of the gus gene using PCR and nucleic acid spot hybridization.
Abstract: Elephant foot yam (Amorphophallus paeoniifolius (Dennst.) Nicolson), is an important edible tropical tuber crop, belonging to the family Araceae. Corms produced by this plant is very big and they are rich in starch, protein, mineral, vitamins, and dietary fiber but has acridity problem. This crop is susceptible to virus and phytoplasma diseases which affects crop growth and corm yield. Even though this crop has high commercial value, the problems like susceptibility to viral diseases, acridity problems, and lack of genetic diversity made hindrance in their exploitation. These issues can be resolved only by improving the characters through genetic transformation. To achieve genetic transformation in this important crop, a study was conducted to optimize various parameters for efficient Agrobacterium-mediated genetic transformation using embryogenic calli with vectors having gus reporter gene. Calli were developed using petiole and leaves of in vitro plantlets of elephant foot yam cultivar Gajendra and experiments were conducted to evaluate the sensitivity of calli to different doses of antibiotics viz. geneticin, hygromycin, ticarcillin. It was observed that complete death and discoloration of the calli were obtained with 25 mgl−1 geneticin and 10 mgl−1 hygromycin. The lowest lethal concentration of ticarcillin against Agrobacterium growth was found to be 500 mgl−1 which did not affect calli growth. Optimized parameters for efficient transformation in elephant foot yam include 100 μM acetosyringone concentration with 2 days of co-cultivation at temperature 22 °C using LBA4404 strain. The putative transformants were characterized for the integration of the gus gene using PCR and nucleic acid spot hybridization. The optimized protocol is simple and reproducible and may be adapted for other cultivars also.
TL;DR: In this article, the impact of climate change on the yield of rice and potato is also carried out using the same crop model to understand the advantages of root and tuber crops over the yield variations of Rice and potato.
Abstract: The current study focused on the impact of climate change on tropical root and tuber crops of India over some of the major growing areas using the crop model, WOFOST. As part of this study, the impact of climate change on the yield of rice and potato is also carried out using the same crop model to understand the advantages of root and tuber crops over the yield variations of rice and potato. The LARS weather generator is used to derive future climate for 2030, 2050, and 2070 for the two representative concentration pathways (RCPs)-4.5 and 8.5. The future climate projections in the study locations indicate an increment in minimum and maximum temperatures up to a value of 3.4 and 3.8 oC respectively. The rainfall also indicates a drastic fluctuation from -721 to 448 mm in the future. The results reveal that the predicted crop yield varies from one location to another depending on the future climate. Cassava (-13 to 12%, -17 to 8%), sweet potato (-32 to 14%, -38 to 13%), greater yam (-11 to 8, -14 to 6), elephant foot yam (-10 to 6, -12 to 4), and taro (-16 to 19, -28 to 18) can be considered as future crops based on their predicted yield variations and economics compared to that of rice (-26 to 15%, -50 to 18%) and potato (-37 to 7%, -59 to 8.5%) for both the RCPs. Among other crops, sweet potato has the same crop duration as rice and potato and can be recommended to increase food access. These crops can be recommended for enhancing the availability of food based on their superiority in dry matter production.
TL;DR: The findings of this study strongly suggest that varieties suitable for processing can be identified among the germplasm based on evaluation of processing traits.

TL;DR: In this article, the suitability of sweet potato flour for development of gluten free spaghetti with reduced starch digestibility and to enhance protein content by fortification of whey protein concentrate (WPC) and chickpea flour (CPF) at the rate of 5, 10, and 15% respectively along with control.
Abstract: The aim of present investigation was justifying the suitability of sweet potato flour for development of gluten free spaghetti with reduced starch digestibility and to enhance protein content by fortification of whey protein concentrate (WPC) and chickpea flour (CPF) at the rate of 5%, 10%, and 15% respectively along with control. The effect of fortification in spaghetti was assessed for its glycemic index, physical, nutritional, and sensory properties. The data revealed that increase in the level of fortification of WPC and CPF resulted with increase in optimum cooking time, weight and volume without affecting cooking loss as compared to control sample. The percent increase in protein content of spaghetti fortified with WPC and CPF found as 192.20% and 150.08% respectively in comparison with control. However, spaghetti fortified with 15% CPF and 15% WPC showed lowest starch digestibility with reduced glycemic index to 59.43 and 58.73 respectively. The spaghetti fortified with 10% WPC and 10% CPF was found overall acceptable by panelists. Moreover, the fortification of spaghetti with WPC and CPF could significantly increase the protein content along with overall acceptability and functional characteristics.

TL;DR: In this article, a study was carried out to test the SIMCAS (growth simulation model for cassava) model over major cassava-growing regions in India with different agro-climatic conditions to understand the wider acceptability of this model.
Abstract: A study was carried out to test the SIMCAS (growth simulation model for cassava) model over major cassava-growing regions in India with different agro-climatic conditions to understand the wider acceptability of this model. The study locations included the major growing areas of cassava in India, viz. Thiruvananthapuram, Salem, Navsari, Ratnagiri, and West Godavari. Two varieties, H-226 (long-duration) and Sree Vijaya (short-duration), were used to validate this model. The crop growth parameters for calibrating the model were derived by conducting field experiments at the five locations under the All India Coordinated Research Project on Tuber Crops. The model verification score and agreement index during yield simulation in the case of H-226 and Sree Vijaya were ranged from 0.69 to 0.99 and from 0.52 to 0.59, respectively. The values of normalized objective function (0.10–0.26) and normalized root mean square error (excellent to fair simulations) also showed the reliability of the model simulations with the field observations. Based on the model performance, this study recommended the wider applicability of SIMCAS for simulating cassava yield irrespective of the agro-climatic conditions.
