Elucidating the downstream pathways triggered by H₂S signaling in <i>Arabidopsis thaliana</i> under drought stress via transcriptome analysis.

ABSTRACT: Hydrogen sulfide (H₂S) is a crucial signaling molecule in plants. Recent studies have shown that H₂S plays an equally important role as nitric oxide (NO) and hydrogen peroxide (H₂O₂) in plant signaling. Previous studies have demonstrated the involvement of H₂S in regulating drought and other stressful environmental conditions, but the exact downstream molecular mechanisms activated by the H₂S signaling molecule remain unclear. In this study, we conducted a comprehensive genome-wide transcriptomic analysis of both wild type (WT) and double mutant (lcd/des1). Arabidopsis thaliana plants were exposed to 40% polyethylene glycol (PEG) to induce drought stress and 20 µM sodium hydrosulfide (NaHS). The resulting trans
