甲醇对植物的作用及其生理机制

Roles of Methanol on Plants and Its Physiological Mechanisms

甲醇是植物生长发育和代谢过程中体内产生的最简单的一碳化合物之一,与植物的很多生理过程(如光合作用、C1-四氢叶酸和某些植物激素生物合成以及植物耐逆性等)密切相关。本文对近年来国内外有关植物中甲醇的产生与释放途径、体内代谢、外施甲醇对植物的效应及其生理机制等方面研究进行了综述,并提出存在的问题和今后研究方向。

The methanol, which is one of the simplest organic C1 compounds produced during the plant growth, development and metabolisms, is related to many plant physiological processes （such as photosyn- thesis,biological synthesis of C^-tetrahydrofolate and some phytohormones, and stress tolerance）. In this paper, the pathways for methanol production and emission, metabolisms, and the role of exogenous applying methanol on plants and its physiological mechanisms are summarized according to the existing references, and on that basis,the present occurred problems and future research focus are also discussed.
