摘要: 植物在整个生长、发育和响应环境胁迫过程中,涉及多种信号分子如钙(Ca2+)、活性氧(ROS)、硫化氢(H2S)和一氧化氮(NO)等的交互作用。近年来,H2S和NO都被认为是植物中重要的第二信使,参与种子的萌发、植物的生长与发育和对环境胁迫的响应和适应,并且在这些生理过程中,存在H2S和NO信号的交互作用。基于H2S和NO信号的最新研究进展,对H2S和NO信号在植物中的合成和分解代谢,以及它们在植物细胞中的动态平衡进行了讨论,并对植物中H2S和NO信号的交互作用,即二者的化学反应、作用于共同的靶分子、调节彼此代谢酶和其他信号途径等方面进行了归纳和总结。

Abstract: During the processes of plant growth,development,and response to environmental stress,which is involved in the crosstalk among signaling molecules,such as calcium(Ca2+),reactive oxygen species(ROS),hydrogen sulfide(H2S),and nitric oxide(NO). Recently,H2S and NO are considered to be important second messengers,which take part in multiple physiological processes,including seed germination,plant growth and development as well as response and adaptation to environmental stress. In these physiological processes,the interplay between H2S and NO can be found. In the light of current research advance on H2S and NO,this review discussed the anabolism and catabolism of H2S and NO in plants,as well as their homeostasis in plant cells. In addition,H2S interaction with NO in plants,by reacting each other,acting on common target molecules,regulating metabolic enzymes each other,and controlling other signaling pathways,was also summarized.
