The global population (presently 8.1 billion) is expanding exponentially at a rate of 1.59% every year, and it expected to reach 9 billion people by 2050. This rapid growth, coupled with significant development, presents major concern for feeding the population, as food production only predicted increase 70% Microbial technology branch biotechnology that advances ecological agriculture combining microorganisms emerging techniques. A key driver abiotic stress, which negatively impacts agricultural productivity an irreversible level threatens sustainable agriculture, climate challenge. Saline, drought, severe heat, other stresses induced change adversely affect morphological, physiological, biochemical, metabolic features plants. ultimately inhibits plant productivity. However, excessive use improper application agrochemicals are detrimental preservation environment natural resources, impeding development agriculture.

The rhizosphere is the region around plant roots where maximum microbial activities occur. In rhizosphere, microorganisms' beneficial and harmful affect growth development. mutualistic rhizospheric bacteria which improve health are known as growth-promoting rhizobacteria (PGPR). They very important due to their ability help in diverse ways. PGPR such Pseudomonas, Bacillus, Azospirillum, Azotobacter, Arthrobacter, Achromobacter, Micrococcus, Enterobacter, Rhizobium, Agrobacterium, Pantoea Serratia now well known. Rhizomicrobiome plays critical roles nutrient acquisition assimilation, improved soil texture, secreting modulating extracellular molecules hormones, secondary metabolites, antibiotics various signal compounds, all leading enhancement of microbes compounds they secrete constitute valuable biostimulants play pivotal stress responses. this review, we highlight diversity cutting-edge findings focusing on role a We also discussed resisting adverse effects arising from abiotic (drought, salinity, heat, heavy metals) stresses.

Increased food production to cater the need of growing population is one major global challenges. Currently, agro-productivity under threat due shrinking arable land, increased anthropogenic activities and changes in climate leading frequent flash floods, prolonged droughts sudden fluctuation temperature. Further, warm climatic conditions increase disease pest incidences, ultimately reducing crop yield. Hence, collaborated efforts are required adopt environmentally safe sustainable agro practices boost growth productivity. Biostimulants appear as a promising means improve plants even stressful conditions. Among various categories biostimulants, microbial biostimulants composed microorganisms such plant growth-promoting rhizobacteria (PGPR) and/or microbes which stimulate nutrient uptake, produce secondary metabolites, siderophores, hormones organic acids, participate nitrogen fixation, imparts stress tolerance, enhance quality yield when applied plants.

Bioaugmented grapevines exposed presented significantly enhanced photoprotection capability higher thermo-stability, exhibiting lower dissipation energy flux than non-inoculated plants. Additionally, rhizobacterial tested improved light-harvesting capabilities increasing reaction centre availability preserving photosynthetic efficiency. Rhizobacteria inoculation expressed osmoprotectant promotion, revealed osmolyte concentration while maintaining leaf turgidity. Improved antioxidant mechanisms membrane stability resulted lowered lipid peroxidation product formation when compared Although found differ their effectiveness, these findings demonstrate that bioaugmentation induced significant tolerance mitigation.
