“…Instead, we found that BIP3 was induced by salt stress (Fig. 4C); BIP3's involvement in the unfolding protein response caused by salinity was recently discussed (Henriquez-Valencia et al, 2015;Guan et al, 2018).…”

Environmental stresses such as drought, heat, and salinity limit plant development and agricultural productivity. While individual stresses have been studied extensively, much less is known about the molecular interaction of responses to multiple stresses. To address this problem, we investigated molecular responses of Arabidopsis to single, double, and triple combinations of salt, osmotic, and heat stresses. A metabolite profiling analysis indicated the production of specific compatible solutes depending on the nature of the stress applied. We found that in combination with other stresses, heat has a dominant effect on global gene expression and metabolite level patterns. Treatments that include heat stress lead to strongly reduced transcription of genes coding for abundant photosynthetic proteins and proteins regulating the cell life cycle, while genes involved in protein degradation are up-regulated. Under combined stress conditions, the plants shifted their metabolism to a survival state characterized by low productivity. Our work provides molecular evidence for the dangers for plant productivity and future world food security posed by heat waves resulting from global warming. We highlight candidate genes, many of which are functionally uncharacterized, for engineering plant abiotic stress tolerance.

“…Cell wall/membrane/envelope biogenesis in microbes may enhance drought and salt stress tolerance by regulating H + -ATPase of the plasma membrane, and these can enhance plant growth and drought tolerance as plant growth-promoting bacteria [38,39]. Some chaperones, such as heat shock proteins, are known as drought tolerance enhancers for plants [40,41]. Thus the vigorous microbial metabolism and basic biological processes in the drought-treated samples may enhance peanut stress tolerance.…”

Background: Peanut (Arachis hypogaea L.), an important oilseed and food legume, is widely cultivated in the semi-arid tropics. Drought is the major stress in this region which limits productivity. Microbial communities in the rhizosphere are of special importance to stress tolerance. However, relatively little is known about the relationship between drought and microbial communities in peanuts. Method: In this study, deep sequencing of the V3-V4 region of the 16S rRNA gene was performed to characterize the microbial community structure of drought-treated and untreated peanuts. Results: Taxonomic analysis showed that Actinobacteria, Proteobacteria, Saccharibacteria, Chloroflexi, Acidobacteria and Cyanobacteria were the dominant phyla in the peanut rhizosphere. Comparisons of microbial community structure of peanuts revealed that the relative abundance of Actinobacteria and Acidobacteria dramatically increased in the seedling and podding stages in drought-treated soil, while that of Cyanobacteria and Gemmatimonadetes increased in the flowering stage in drought-treated rhizospheres. Metagenomic profiling indicated that sequences related to metabolism, signaling transduction, defense mechanism and basic vital activity were enriched in the drought-treated rhizosphere, which may have implications for plant survival and drought tolerance. Conclusion: This microbial communities study will form the foundation for future improvement of drought tolerance of peanuts via modification of the soil microbes.

“…Many scientists have paid great attention to investigate the mechanisms of plant salt-tolerance and salt-adaption using genomic and proteomic technologies (Shah et al 2018;Wu et al 2016). Arabidopsis thaliana is an ideal material to investigate the salt-responsive molecules (Guan et al 2018;Zhang et al 2018;Huang et al 2018). But previous research only provided limited information.…”

Salt stress negatively affects plant growth and crop productivity. As an ideal model pathway of salt tolerance in glycophyte. To better understand the molecular mechanisms of salt-response in glycophyte, 466 of 15,768 Arabidopsis thaliana proteins with the GO term of biological with known genetic background, Arabidopsis thaliana has been widely applied to disclose the process 'response to salt stress' were retrieved from UniPort and analyzed by bioinformatics tools of PANTHER, DAVID, KEGG, Cytoscape and STRING. Our results not only indicated the involvement of salt-responsive proteins in various pathways and interaction networks, but also demonstrated the more complicated cross-tolerances to both abiotic stresses (osmosis, water deprivation, abscisic acid, cold, heat, light and wounding) and biotic stresses (bacterium and fungus) and multiple subcellular locations of these salt-responsive proteins. Furthermore, protein activities of superoxide dismutase (SOD) and peroxidase (POD) in Arabidopsis thaliana were determined under salt, cold and osmotic stresses, which validated the hypothesis of cross-tolerance to multiple stresses. Our work will greatly improve the current knowledge of salt tolerance mechanism in glycophytes and provide potential salt-responsive candidates for promoting plant growth and increasing crop output.
