Abstract excerpt
The phytohormone abscisic acid (ABA) plays pivotal roles in triggering stomatal closure and facilitating adaptation of plants to drought stress. Hydrogen sulfide (H2S), a small signaling gas molecule, is involved in ABA-dependent stomatal closure. However, how H2S regulates ABA signaling remains largely unclear. Here, we show that ABA induces the production of H2S catalyzed by L-CYSTEINE DESULFHYDRASE1 (DES1) in...
