Abstract
Global ecosystems are confronting formidable challenges stemming from climate change, environmental pollution, and intensive farming practices. Among these hurdles, recurrent and severe water-deficit stress stands out as a significant threat to plants in both natural habitats and managed agricultural settings. Roots, together with the intricate microenvironment of the rhizosphere, wield considerable influence over crop responses to water deficit, thereby shaping overall ecosystem health and resilience. In the realm of water scarcity challenges, crop root systems assume a central role in shaping the rhizosphere. Root exudates, encompassing organic acids, sugars, and phenolic compounds, emerge as pivotal influencers, sculpting microbial communities and serving as vital nutrient sources. The dynamic interplay among these components under drought stress profoundly alters the composition and structure of rhizosphere microbial communities. Additionally, the plant’s tailored responses contribute to the selective recruitment of beneficial microorganisms, facilitated by root-derived signals. This chapter delves into the intricate web of interactions within the rhizosphere, offering invaluable insights into how these responses resonate through plant-microbe relationships and impact ecosystem functioning in the challenging context of drought stress.
