TL;DR: The results demonstrate that the active antioxidative defence mechanisms of 4x plants increase their tolerance to salinity compared to their corresponding 2x relatives, and the use of newly developed tetraploid rootstocks may be a strategy for enhancing crop production in saline conditions.

TL;DR: Results suggest that SbWRKY30 functions as a positive regulator in response to drought stress, and may serve as a promising candidate gene for molecular breeding to generate drought-tolerant crops.

TL;DR: The biochemical properties of Rubisco have underpinned the mechanistic mathematical models of photosynthetic CO2 fixation which link Rubisco kinetic properties to gas exchange of leaves and allowed assessments of global CO2 exchange and predictions of how Rubisco has and will shape the environmental responses of crop and global photosynthesis in future climates.

TL;DR: Novel results suggest that interaction of Ca2+/CaM and Mel is involved in overcoming salt-induced ionic, osmotic, and oxidative damages and Ca2- and Mel may act as long-distance signals for inducing systemic salt tolerance in D. kotschyi.

TL;DR: The alleviation effects of spraying phytohormones under drought stress increased the endogenous hormone contents, enhanced carbon metabolism enzyme activities, improved the photosynthetic fluorescence characteristics of leaves, and regulated the source-sink balance, all of which alleviated the yield reduction caused by drought stress.

TL;DR: Investigation of strategies that WB plants utilise in regard to the control of stomatal operation and ionic homeostasis to deal with salinity stress suggests that CB employ a stress-escaping strategy by reducing stomata density, to conserve water, when grown under salinity conditions.

TL;DR: A PCA and discriminant analysis were able to efficiently discriminate different species displaying spectra overlapping, and strong overlapping signatures of phenolics, carotenoids, chlorophylls, flavonoids and anthocyanins were observed.

TL;DR: The results suggest that melatonin could positively alter tea growth and quality by modulating the photosynthesis and biosynthesis of polyphenols, amino acids, and caffeine in tea leaves under SHT.

TL;DR: It is concluded that low-N stress increases shoot-to-root auxin transport which enhances root elongation via auxin-dependent acid growth and the Auxin-regulated TOR pathway in maize.

TL;DR: The results suggest that cell wall modifications due to environmental acclimations can play a significant role in leaf physiology by affecting distinctly photosynthesis and water relations in a manner that might depend on environmental conditions.

TL;DR: The effects of a newly discovered endophytic fungus, Talaromyces omanensis, on the drought tolerance of tomato is presented in this study, the first to report the beneficial effects of T. o manensis in alleviating drought stress in tomatoes.

TL;DR: The effect of IAA on the internal cell component of root water conductivity suggests that aquaporins are involved in the IAA-dependent inhibition of this water pathway.

TL;DR: The barley mutants with a BR deficiency or with BR signalling disturbances were characterised by an altered accumulation level of PM H+-ATPase, the aquaporin HvPIP1 transcript and protein (compared to the wild types), which may suggest the involvement of brassinosteroids in regulating PM H-atPase and aquaporIn HVPIP1 at the transcriptional and translational levels.

TL;DR: Results indicate that ABA can initiate anthocyanin biosynthesis, which ultimately improves the color and nutritional value of fig fruit, enhancing their attractiveness to consumers.

TL;DR: Fruit cracking was correlated with whether wax synthesis is coordinated with fruit enlargement and 'Popozao' has a stronger ability to synthesize very-long-chain alkanes and aldehydes, and Gene expression analysis indicated that KCS1, CER1, CYP86B1, and CYP 86A play crucial roles in wax formation on jujube fruit.

TL;DR: The study reveals that in Arabidopsis thaliana the mitochondrial/chloroplast C-to-U RNA editing rates are reduced under heat or cold stress, and proposes a potential role of editing sites in the heat response.

TL;DR: The clones showed differences in their phenological development, which conditioned some responses to elevated CO2 and temperature in terms of vegetative production and C partitioning into different organs, which adds new knowledge on the use of different grapevine clones, that can be useful to improve the viticultural efficiency in future climate change scenarios.

TL;DR: The data provide comprehensive insight into the whole-plant transcriptomic response in terms of metabolic processes and signaling transduction to a low-NH4+ signal, and identify the transcription factor OsJAZ9 and its involvement in the regulation of carbon/nitrogen metabolism as central to the response to low NH4+.

TL;DR: The results indicated that Bacillus amyloliquefaciens YTB1407 played a pivotal role in enhancing resistance to two fungi pathogens in sweet potato, through production of some antifungal metabolites to decrease infection in the early stage as well as induction of SA-dependent systemic resistance.

TL;DR: Results indicate that NO2-OA triggers NADPH oxidase activation revealing a new signaling role in plants, resembling plant defense responses.

TL;DR: It is found that the various polyamines differentially affected the metabolism of nitric oxide and reactive oxygen species during the processes of pollen germination in the grain and the lengthening pollen tube.

TL;DR: This work presents an approach for the estimation of the efficiency by three foliar pigment groups at capturing light, via the absorption coefficient derived from leaf reflectance spectra, which improves the understanding of the phenological, physiological and photosynthetic dynamics of plants over space and through time.

TL;DR: The antioxidant response of Scenedesmus sp.

TL;DR: Results indicate that soybean circRNAs might encode proteins and be involved in the regulation of LT responses, providing clues regarding the molecular LT-responsive mechanisms in soybean.

TL;DR: It is recommended that a PFD of 200 μmol m-2 s-1 with DLI at 11.9 is suitable for hydroponic sweetpotato (cv. Beniharuka) seedling production under a controlled environment, and white LEDs showed higher light energy use efficiency than white plus red LEDs.

TL;DR: The present study is the first to analyze the CaM/CML gene family in B. napus, which is useful for understanding the functions of the BnaCaM /CML in modulating plant responses to abiotic stress, especially freezing stress.

TL;DR: The peanut-P4 association could potentially model the beneficial Pseudomonas-driven multi-trophic rhizosphere benefits, emphasizing the plausible role of non-rhizobium PGPR in promoting N2 fixation.

TL;DR: Basic knowledge about phytoremediation through overexpression of MLP genes and for breeding cucurbits that accumulate less contaminants are provided.

TL;DR: Results suggested that TaHsfA2-1 is a new gene that improves thermotolerance in plants by mediating the expression of heat shock protein genes (Hsps) compared to wild type after heat stress.

TL;DR: It is concluded that a complex hormonal interplay, rather than ethylene alone, modulates postharvest ripening of avocados and that cold storage can effectively be employed as a technique to prevent avocado from a rapid ripening thanks to the cold stress tolerance mechanisms deployed by fruits through multiple hormonal regulation.
