The rising threat of climate change has forced the scientific community to think seriously on key research areas, especially within agricultural biology. Climate change impacts numerous abiotic stress factors that exert an influence on productivity and nutrient uptake in crops, including high/ low temperature, salinity, drought and flood. Combating the consequences of climate change is extremely important and critical in meeting the feeding requirements of the world’s burgeoning population. Plant growth promoting rhizobacteria (PGPR) are an important group of beneficial soil bacteria involved in an array of activities of ecological significance. They promote plant growth by alleviating abiotic stress tolerance, support the nutrition uptake of plants and increase crop productivity through various mechanisms. especially through altering plant hormones or metabolites.
Beneficial soil microbes such as plant growth promoting rhizobacteria plays a key role in mitigating abiotic stresses and improves agricultural sustainability. The soil microenvironment around plant roots harbors diverse microorganisms (such as Pseudomonas, Bacillus etc.) that accelerate plant growth by acquiring nutrients through nitrogen fixation, micronutrient uptake, influencing plant hormone pathways, phosphate and zinc solubilization, siderophore release and hydrogen cyanide production, or by inducing plant systemic resistance through production of secondary metabolites and stress responsive enzymes. Several studies have reported the role of rhizobacteria in production of stress responsive enzymes and metabolites to mitigate abiotic stress. However, there are limited genomic, proteomic and metabolomic studies exploring the mechanisms of how rhizobacteria alleviate abiotic stresses for plants.
In the last two decades, many studies have characterized key metabolic pathways involved in producing metabolites associated with abiotic stress tolerance. However, there is still much to be understood about the diversity of metabolites and their mechanisms, as well as their biosynthetic pathways.
The proposed Research Topic will focused on recent advances in agricultural microbiology where beneficial plant growth promoting rhizobacteria can aid in reducing the negative effects of abiotic factors that exert stress in crop plants. This especially includes the use of genomic, proteomic and metabolomic approaches to understand the mechanisms involved in the mitigation of abiotic stresses in crop plants by rhizobacteria.
