Salicylic Acid Regulation of Rhizome Network Nutrient Uptake in Leguminosae Under Drought Stress

* *Salicylic Acid Regulation of Rhizome Network Nutrient Uptake in Leguminosae Under Drought Stress**

# # Abstract

Leguminosae, a diverse group of perennials, have evolved intricate rhizome networks to optimize nutrient uptake under varying environmental conditions. Salicylic acid (SA), a key phytohormone, plays a pivotal role in regulating rhizome network responses to drought stress. This study investigates the mechanisms underlying SA-mediated signaling in Leguminosae, with a focus on rhizome network nutrient uptake under drought stress. We employed quantitative real-time polymerase chain reaction (qRT-PCR) and precision agriculture with soil moisture sensors to examine SA-regulated gene expression, root exudate secretion, and nutrient uptake in legume species. Our results demonstrate that SA modulates rhizome network activity, enhancing nutrient uptake and promoting drought tolerance in Leguminosae. These findings have significant implications for perennial cropping with cover crops, improved soil health, and precision agriculture.

# # Key Findings
