Hydrogen sulfide regulates energy production to delay leaf senescence induced by drought stress in Arabidopsis (Front Plant Sci)
Premature leaf senescence can occur due to a mutation of a L-cysteine desulfhydrase1 (DES1) gene that encodes an enzyme that produces hydrogen sulfide (H2S), a “gasotransmitter” with functions in plants as well as mammals. Jin et al. explored the physiological functions of H2S in Arabidopsis. In addition to accelerated leaf senescsence and higher drought stress-sensitivity, des1 […]
