Hub metabolites at the root–microbiome interface: unlocking plant drought resilience Drought is one of the most devastating environmental challenges, severely affecting agriculture, ecosystems, and global food security. Effective strategies to predict and mitigate drought are limited. The root–soil–microbiome interface is pivotal in mediating plant resilience to drought. Recent studies highlight dynamics between plant root exudates and microbial communities, influencing stress tolerance through chemical signaling under drought. By integrating plant molecular biology, root chemistry, and microbiome research, we discuss insights into how these mechanisms can be harnessed to enhance crop resilience. Here, we focus on the interplay between plants and their microbiomes with metabolites as a central point of interactions. We synthesize recent developments, identify critical knowledge gaps, and propose future directions to leverage plant–microbe interactions to improve plant drought tolerance. http://dlvr.it/TKtJ4k
