摘 要:

唾液蛋白是刺吸式口器介体昆虫唾液的重要成分,在昆虫取食过程中调控寄主植物的防御反应、自身取食的顺利进行和病毒的有效传播。本文围绕昆虫唾液蛋白与植物防御反应的“攻- 守”关系,阐述唾液蛋白作为激发子触发植物防御反应,以及作为效应子抑制植物防御反应的作用机制,论述了唾液激发子和效应子对介体昆虫取食和传播病毒的影响。介体昆虫唾液蛋白作为介导病毒传播的跨界信号,将成为制定病害调控策略的重要靶标。昆虫唾液蛋白的研究也将为开拓植物病毒病有效防控的新技术提供重要的理论基础。

Abstract:

Salivary proteins are important components of piercing-sucking insect saliva, and regulate the defense of plant hosts to promote feeding and effective transmission of plant viruses. Focusing on the “attack-defense” relationship between insect salivary proteins and plant defense responses, this review describes the mechanism of salivary proteins as elicitors triggering plant defenses and as effectors inhibiting plant defenses. The effects of salivary elicitors and effectors on insect feeding and virus transmission are also reviewed. Salivary proteins of insect vectors, serving as cross-kingdom signals mediating viral transmission, will be an important target for making strategy of disease management. The investigation on insect salivary proteins will also theoretically base for developing a new effective control technology of plant virus disease.
