基于酶活性对稻瘟病菌的抑制机制研究进展
摘要:稻瘟病菌是水稻最重要的传染性真菌病害,其生理小种的变异较快,抗病品种的培育较为困难,因此田间以农药防治为主。根据国内外对蒽醌类、大黄类化合物等抑菌物质抑菌性,对细胞壁、细胞膜、体内代谢、遗传物质转录等相关酶抑菌机理的研究作了概述。

Abstract:Magnaporthe oryzae is the most important infectious fungal disease of rice, its physiological races vary rapidly, and it is difficult to cultivate resistant varieties, so pesticide control is the main method in the field. According to the bacteriostatic effects of anthraquinones and rhubarb compounds at home and abroad, the bacteriostatic mechanisms of related enzymes such as cell wall, cell membrane, metabolism in vivo and transcription of genetic material were summarized.
Key words:Plant fungi; Magnaporthe oryzae; Anthraquinone compounds; Emodin compounds; Related enzymes; bacteriostatic
稻瘟病菌(Magnaporthe oryzae)是一种真菌,属半知菌类丛梗孢科梨孢属,是引起水稻稻瘟病的主要因素。稻瘟病菌以分生孢子和菌丝体在稻草和稻谷上越冬,主要通过其分生孢子借风雨传播附着在寄主上,吸取植株营养形成发芽管,接着特异性分化为具有黑色素的附着胞,进而产生侵染栓进行侵染。水稻是我国的主要粮食之一,水稻病虫害的防治也成为了一些地区面临的棘手难题。稻瘟病又名稻热病,是流行最广、危害最大的世界性真菌病害之一,主要危害寄主植物的地上部分,可引起大幅度减产,甚至绝收[[1]]。
