ABSTRACT
Recurring climate change results in the generation of different abiotic stress factors, such as extreme temperatures, drought, flooding, UV radiation, salinity and heavy metal, around the world, which further become one of the bases for major losses to crop production. Microorganisms found in different environmental conditions exhibit enormous metabolic capabilities to cope with abiotic stresses. Microbes found in extreme habitats developed a different strategy to adapt to such condition through evolution. Several biomolecules found in microorganism are reported to be involved in providing stress tolerance. Proteomics is an excellent methodology to produce a better understanding of the regulation of biological systems by identifying several proteins as a signal of changes in physiological status due to stress or factors responsible for stress alleviation. Plant-associated microbial communities currently have received increased attention for enhancing crop productivity and providing stress tolerance to plants. Flooding stress imposes a number of challenges to normal plant functioning. Flooding affects soil nutrient availability and oxygen depletion.
