Abstract

Nitro-oxidative stress in plants involves reactive oxygen and nitrogen species overproduction, which could trigger irreversible cellular damage. In this context, a novel signaling gaseous molecule, hydrogen sulfide (HS), has emerged, which appears to stimulate the antioxidant system and is capable of mediating effective mechanisms of response to these abiotic stresses.

摘要

植物中的氮氧化应激涉及活性氧和氮物种的过度产生，这可能会引发不可逆转的细胞损伤。在这种情况下，一种新型的信号气态分子——硫化氢 (HS) 已经出现，它似乎能刺激抗氧化系统，并能介导对这些非生物胁迫的有效响应机制。
