Plant growth promoting microorganisms mediated abiotic stress tolerance in crop plants: a critical appraisal

Under the constant strain of rising environmental changes it is now more important than ever to describe and understand plant microbe interactions in terms of abiotic stress resistance. Multi omics including transcriptomics, genomics, RNomics etc. like approaches bring together studies on plants interactions with microbes and plant growth regulators to provide multi layered data. Comprehensive understanding of plant microbe mediated mechanisms and hormone signaling networks for abiotic stress tolerance is necessary to translate their practical use for plant survival under extreme conditions. This will pave the way for climate smart agriculture research that will help in progress and manipulation of advantageous microbes and plant regulators as foundation of crop acclimation to changing climatic conditions thereby strengthening further sustainable agriculture. For crop development, it is crucial to understand the fine tuning and integration of many signals created by microbial interactions in plants. This study discusses plant responses to microbe mediated stress relief that have been documented so far. Analyzing the plant characteristics that were heterogeneously related to soil metabolites, minerals, and microorganisms utilizing omics techniques. This will aid in the further adoption of omics-based methodologies while taking into account the various tactics used by microorganisms. Present review provides indepth understanding of the interplay between Plant growth promoting microorganisms with crop plants to circumvent the undesirable impacts of environmental stress on crop cultivar and will help to implement omics based strategies to overcome abiotic stresses in plants.
