| 摘 要： | 植物病原卵菌是一类农业生产上为害巨大的病原物，其分泌大量的RXLR效应分子进入寄主植物细胞并干扰植物免疫系统，以协助病原菌成功侵染。尽管有一小部分RXLR效应分子会被植物识别成为无毒蛋白，但大部分RXLR效应分子则会逃避识别和抑制植物免疫。随着高通量测序和蛋白互作技术的广泛应用，大量RXLR效应分子干扰植物免疫的分子机制已经被揭示。本文综述了RXLR效应分子操纵植物免疫系统的分子策略，探讨了RXLR效应分子与植物免疫互作的研究方向和应用前景。

| Abstract: | Phytopathogenic oomycetes represent a class of destructive phytopathogens to agricultural production. Oomycetes secrete numerous RXLR effectors that enter plant cell and interfere with host immunity and thus facilitate successful infection. Though a few RXLR effectors are recognized by plants as the avirulence protein, most RXLR effectors can escape such recognition and suppress plant immunity. With the widespread application of high-throughput sequencing and protein-protein interaction technology, various molecular mechanisms by which RXLR effectors interferes plant immunity have been revealed. Here we summarize the strategies of RXLR effectors manipulating plant immunity, and discuss the research directions and application prospect of RXLR effectors interacting with plant immunity. |
