【摘要】 丝裂原活化蛋白激酶(MAPK)级联信号通路是真核生物中广泛存在的信号转导途径。非生物胁迫是植物面临的首要挑战，随着极端气候的频发和环境污染问题的加剧，开展植物MAPK级联信号通路在非生物胁迫下的机理研究迫在眉睫。对近年模式植物拟南芥，主要农作物水稻、玉米和小麦等，以及重要园艺作物中MAPK信号通路响应干旱、盐胁迫、极端温度及营养匮乏等方面的研究进行了总结归纳，并对其进一步的研究工作进行了展望。结果表明，MAPK作用于植物响应非生物胁迫信号转导，并在植物抗逆过程中扮演重要角色。研究MAPK作用机制将对阐明植物抗逆分子网络，培育抗性品种和提高作物产量等方面具有重要意义。更多还原

【Abstract】 Mitogen-activated protein kinase(MAPK) cascade signaling pathway is a widespread signal transduction pathway in eukaryotes. Abiotic stress is the primary challenge of plants. With the frequent occurrence of extreme climate and the aggravation of environmental pollution, it is extremely urgent to study the mechanism of MAPK cascade signaling pathway in plants under abiotic stress. In this paper, the response of MAPK signaling pathway to drought, salt stress, extreme temperature and nutrient deficiency in model plant arabidopsis, major crops(rice, maize and wheat) and important horticultural crops in recent years were summarized. The future researches of MAPK signaling pathway were prospected. The results show that MAPK signal transduction plays an important role in plant response and resistance to abiotic stress. The studies of the mechanism of MAPK will be of great significance to elucidate the molecular network of plant stress resistance, cultivate resistant varieties and improve crop yield.更多还原
