TL;DR: The results of these reviews can know how developmental and environmental factors qualitatively and quantitatively influence SMs of medicinal plants and how these can be integrated as tools to quality control, as well as on the improvement of clinical curative effects by altering their genomes, and/or growth conditions.

TL;DR: This review paper evaluates the physiological and biochemical responses of the plant to salinity along with phytohormone response and highlights omics approach to understand salt stress tolerance.

TL;DR: The results highlight that the increase in R/S ratio caused by the changes of sugar allocation, metabolism, and transport under drought stress contributes towards drought resistance of soybean.

TL;DR: The present research underlines the hazardous nature of nano PS, that for their ability to be internalized into crop plants, can enter into different trophic levels of the food chain.

TL;DR: Seed priming with silver nanoparticles could enhance salinity tolerance in crop plants by enhancing physiological and biochemical responses and might boost global crop production in salt-degraded lands.

TL;DR: Results suggest that combined application of Kn and EBL regulate growth and photosynthesis in tomato more effectively than their individual application through a probable regulatory crosstalk mechanism.

TL;DR: This updated review focuses on recent advances in the understanding of the mechanisms underlying plant responses to flooding stress, and summarizes the functions of the flooding response factors involved in energy metabolism and phytohormone biosynthesis/signaling cascades.

TL;DR: Pretreatment of plants with T4C induced unique changes in the drought tolerant EC-98 cultivar such as higher mRNA levels of proline biosynthetic and catabolic ProDH genes, even in the absence of water stress.

TL;DR: The negative effects of Cr toxicity could be overturned by Fe-lys application, significantly increasing plant growth, biomass, chlorophyll content, and gaseous exchange attributes by reducing oxidative stress (H2O2, MDA, EL) and enhancing antioxidant enzyme activities.

TL;DR: Results of greenhouse experiment against Sugarcane red rot indicated that inoculation of B. xiamenensis to sugarcane plants could suppress the disease symptoms and enhance plant growth, and the future application of native multi-stress tolerant bacteria as bio-control agents in combination with current heat, drought, salinity, and heavy metal tolerance strategy could contribute towards the global food security.

TL;DR: Among the NPs, nSiO2 showed higher amelioration effects and it can be used alone or in combination with other NPs to mitigate chilling stress in sugarcane.

TL;DR: No produced by SA up-regulated the activities of AsA-GSH cycle and antioxidant enzymes, so it could play a central function as a signal molecule in salt tolerance of pepper plants.

TL;DR: It is suggested that Pro is a key factor in Si-induced salt tolerance, and Si-increased Pro content may participate in the regulation of cytokinin metabolism under short-term of salt stress.

TL;DR: Results showed that mycorrhizal colonization enhanced apple drought tolerance by improving gas exchange capacity, increasing chlorophyll fluorescence parameters, creating a greater osmotic adjustmentcapacity, increasing scavenging of reactive oxygen species (ROS), and using MAPK signals for interactions between AMF and their apple plant hosts.

TL;DR: It is demonstrated that pretreatment of quinoa seeds with CaCl2, H2O2 and SNP at 5, 5 and 0.2 mM, respectively, concentration is needed to achieve rapid germination at high levels under optimal and salt-stress conditions.

TL;DR: VA significantly improves salinity tolerance and plant growth performance by involving the actions of plant antioxidant defense and glyoxalase systems.

TL;DR: The present review mainly focused on aquaporin functional activity during solute transport, plant development, abiotic stress response, and plant-microbe symbiosis.

TL;DR: It is suggested that Si could improve cucumber growth under nitrate stress by enhancing nitrogen assimilation and chlorophyll synthesis, and imply an application of Si fertilizer in solving secondary soil salinization in protected facilities.

TL;DR: First report of B. xiamenensis as phytoremediator and its inoculation on Sesbania plant was revealed, revealing improved plant growth and induced heavy metal stress tolerance in spiked soils.

TL;DR: Results indicate that the effects ofmelatonin application are associated with a boost in leaf antioxidant enzymes and abscisic acid, and support that the application of melatonin is a promising tool for mitigating salt stress in strawberry.

TL;DR: It is postulate that Ca in association with NO and H2S mitigates Cd-induced impairment and enhances the tolerance of the V. radiata plants against Cd stress.

TL;DR: It is postulate that NO-induced internal H2S conferred tolerance of tomato seedlings to Cr(VI) toxicity and maintained better photosynthesis process and plant growth.

TL;DR: Based on shoot dry weight, CCRI-69 and XLZ-30 were identified as N-efficient and N-inefficient genotypes, respectively, and these results were confirmed by their contrasting root systems, N metabolism, and NUEs.

TL;DR: Combined roles for H2S and GSH to strengthen membrane integrity against Cr stress in maize seedlings are indicated, associated with the attenuation of MG toxicity by enhancing S- lactoglutathione and D-lactate production.

TL;DR: Results reveal that Si could help in the modulation of Chl metabolism, redox hemostasis, and the regulation of nutrients (nitrogen, phosphorus, Si and potassium) uptake in the mustard plants that lead to the postponement of premature leaf senescence under salinity plus DS.

TL;DR: The two mechanisms induced by melatonin synergistically enhance drought resistance of rapeseed as indicated by enhanced gas exchange parameters under melatonin pretreatment, providing evidence for a physiological role of melatonin in improving drought resistance, especially in belowground parts.

TL;DR: Overall, two important mechanisms of drought tolerance in R. damascena are identified-osmotic and elastic adjustment-but they could not offer resistance to water stress beyond 25% FC.

TL;DR: In this paper, physiological analyses revealed that pretreatment with 100μM dopamine alleviated drought stress in apple seedlings. But, the underlying mechanism remains unknown, although dopamine is produced in plants and has been linked with response to abiotic stress.

TL;DR: In current study, inoculation of IAA, EPS and ACC-deaminase producing bacteria enhances plant growth and nutrient availability by minimizing metal-induced stressed conditions.
