Abstract

The results presented demonstrate that microbial pathogens of plants have the ability to secrete proteins which effectively inhibit an enzyme synthesized by the host; an enzyme whose substrate is a constituent of the cell wall of the pathogen. The system in which this was discovered is the anthracnose-causing fungal pathogen (Colletotrichum lindemuthianum) and its host, the French bean (Phaseolus vulgaris). An endo-beta-1, 3-glucanase present in the bean leaves is specifically inhibited by a protein secreted by C. lindemuthianum. The cell walls of C. lindemuthianum are shown to be composed largely of a 1, 3-glucan.

摘要

研究结果表明,植物病原菌具有分泌蛋白的能力,这种蛋白能有效地抑制由宿主合成的一种酶;而这种酶的底物是病原菌细胞壁的组成成分。人们在研究炭疽病真菌病原菌(菜豆壳球孢菌)及其宿主普通菜豆时发现了这个系统。菜豆叶片中的一种内切-β-1,3-葡聚糖酶可被菜豆壳球孢菌分泌的一种蛋白特异性抑制。菜豆壳球孢菌的细胞壁主要由 1,3-葡聚糖组成。
