Recent studies have demonstrated that hydrogen sulfide (H2S) produced through the activity of l‐cysteine desulfhydrase (DES1) is an important gaseous signaling molecule in plants that could participate in abscisic acid (ABA)‐induced stomatal closure. However, the coupling of the DES1/H2S signaling p...
