Plant diseases caused by pathogens and pests lead to crop losses, posing a threat to global food security. The secretory pathway is an integral component of plant defense. The exocyst complex regulates the final step of the secretory pathway and is thus essential for secretory defense. In the last decades, several subunits of the exocyst complex have been reported to be involved in plant defense, especially Exo70s. This comprehensive review focuses on the functions of the exocyst Exo70s in plant immunity, particularly in recognizing pathogen and pest signatures. We discussed Exo70's interactions with immune receptors and other immune-related proteins, its symbiotic relationships with microbes, and its role in non-host resistance. Finally, we discussed the future engineering breeding of crops with resistance to pathogens and pests based on our current understanding of Exo70s.
由病原体和害虫引起的植物病害会导致作物损失，对全球粮食安全构成威胁。分泌途径是植物防御的一个重要组成部分。外泌体复合体调节分泌途径的最后一步，因此对于分泌防御至关重要。在过去几十年中，据报道外泌体复合体的几个亚基参与植物防御，尤其是Exo70s。这篇综述重点关注外泌体Exo70s在植物免疫中的功能，特别是在识别病原体和害虫特征方面。我们讨论了Exo70与免疫受体和其他免疫相关蛋白的相互作用、它与微生物的共生关系以及它在非寄主抗性中的作用。最后，基于我们目前对Exo70s的理解，讨论了未来抗病原体和害虫作物的工程育种。
