Plant viruses pose serious threats to stable crop yield. The majority of them are transmitted by insects, which cause secondary damage to the plant host from the herbivore-vector's infestation. What is worse, a successful plant virus evolves multiple strategies to manipulate host defenses to promote the population of the insect vector and thereby furthers the disease pandemic. Jasmonate (JA) and its derivatives (JAs) are lipid-based phytohormones with similar structures to animal prostaglandins, conferring plant defenses against various biotic and abiotic challenges, especially pathogens and herbivores. For survival, plant viruses and herbivores have evolved strategies to convergently target JA signaling. Here, we review the roles of JA signaling in the tripartite interactions among plant, virus, and insect vectors, with a focus on the molecular and biochemical mechanisms that drive vector-borne plant viral diseases. This knowledge is essential for the further design and development of effective strategies to protect viral damages, thereby increasing crop yield and food security.

植物病毒及其昆虫载体对茉莉酸酯信号的操纵。

植物病毒严重威胁稳定的农作物产量。它们中的大多数是由昆虫传播的，这些昆虫由于食草动物媒介的侵扰而对植物宿主造成了继发性损害。更糟糕的是，成功的植物病毒会进化出多种策略来操纵宿主防御系统，从而促进昆虫媒介的种群，从而进一步加剧疾病大流行。茉莉酸（JA）及其衍生物（JAs）是基于脂质的植物激素，其结构与动物前列腺素相似，赋予植物防御各种生物和非生物挑战的能力，尤其是病原体和食草动物。为了生存，植物病毒和草食动物已经进化出策略来收敛地靶向JA信号。在这里，我们回顾了JA信号在植物，病毒和昆虫载体之间的三方相互作用中的作用，重点研究了媒介载体植物病毒疾病的分子和生化机制。这些知识对于进一步设计和开发保护病毒损害的有效策略至关重要，从而可以提高作物产量和粮食安全。
