日前,科学杂志Science以研究长文“Research Article”在线发表了南京农业大学王源超教授团队关于作物疫病发生机制的突破性成果,该成果揭示了病原菌攻击宿主的全新致病机制“诱饵模式”(DECOY),为改良作物的持久抗病性提供了重要的新方向。该研究发现疫霉菌在侵染植物早期向胞外分泌糖基水解酶XEG1攻击植物细胞壁,而植物则利用水解酶抑制子GIP1抑制其活性;在进化的过程中,病原菌又获得了XEG1的失活突变 Recently, science magazine Science published a breakthrough article about the mechanism of crop blight caused by Professor Wang Yuanchao from Nanjing Agricultural University on the article “Research Article”, which revealed a new pathogenic mechanism of pathogen attacking hosts. "(DECOY) provides an important new direction for improving the long-lasting disease resistance of crops. In the present study, Phytophthora infestans attack plant cell walls with extracellularly secreted glycosyl hydrolase XEG1, whereas plants use the hydrolase inhibitor GIP1 to inhibit its activity. In the process of evolution, the inactivation of XEG1 was also obtained
