Climate change and agriculture are intrinsically connected sudden changes in climatic conditions adversely impact global food production security. The climate change-linked abiotic stressors like drought high temperatures resulting crop failure. most severe stress significantly affect the stomatal closure, of reactive oxygen species, transpiration, photosynthesis or other physiological processes plant morphology, growth yield. Therefore, there is an exigent need for cost effective eco-friendly modern technologies to induce tolerance plants leading climate-adapted sustainable agricultural practices sustained production. Among many options being pursued this regard, use promoting microbes (PGPMs) approach promote resilience better productivity. These PGPMs confer resistance via various direct indirect mechanisms including antioxidants, enzymes, exopolysaccharides, modulation phytohormones level, osmotic adjustment by inducing accumulation sugars, along with increases nutrients, water uptake photosynthetic pigments. However, several technological ecological challenges limit their sometimes treatment beneficial fails produce desired results under field conditions. Thus, development synthetic microbial communities host mediated microbiome engineering transgenic capacity express traits may survival present review critically assesses research evidence on potentials genes as develop resilient increased Effective collaboration among scientific communities, policymakers regulatory agencies needed create strong frameworks that both regulate utilization agriculture.

Cereal plants form complex networks with their associated microbiome in the soil environment. A system including variations of numerous parameters properties and host traits shapes dynamics cereal microbiota under drought. These multifaceted interactions can greatly affect carbon nutrient cycling offer potential to increase plant growth fitness drought conditions. Despite growing recognition importance agroecosystem functioning, harnessing root remains a significant challenge due interacting synergistic effects between traits, properties, agricultural practices, drought-related features. better mechanistic understanding root-soil-microbiota associations could lead development novel strategies improve production In this review, we discuss for improving environment suggest roadmap benefits these drought-resilient cereals. methods include conservative trait-based approaches selection breeding genetic resources manipulation environments.
