Abstract：
The intricate relationships between plants and insects are essential for understanding ecological dynamics. Among these interactions, HIPVs serve as a pivotal defense mechanism. Our findings reveal the highly conserved nature of the GOX gene within the Lepidoptera order, highly expressed in the salivary glands of S. frugiperda, and its role in mediating maize\'s defense responses. Notably, salivary GOX activity expression significantly decreases subsequent gene knockout. The presence of GOX in the saliva of S. frugiperda significantly modulates the emission of HIPVs during maize consumption. This research delineates that GOX selectively inhibits the emission of certain green leaf volatiles (GLVs) while concurrently enhancing the release of terpene volatiles. This study unveils a novel mechanism whereby S. frugiperda utilizes GOX proteins in OS to modulate volatile emissions from maize, offering fresh perspectives on the adaptive evolution of phytophagous insects and their interactions with their preferred host plants.
摘要：
植物和昆虫之间复杂的关系对于理解生态动态至关重要。在这些互动中，HIPV是一种关键的防御机制。我们的发现揭示了鳞翅目中GOX基因的高度保守性，在S.frugiperda的唾液腺中高度表达，及其在介导玉米防御反应中的作用。值得注意的是,唾液GOX活性表达显著降低后续基因敲除.在玉米食用过程中,水果链球菌唾液中GOX的存在显著调节HIPV的排放。这项研究描述了GOX选择性地抑制某些绿叶挥发物（GLV）的排放，同时增强了萜烯挥发物的释放。这项研究揭示了一种新机制，S.frugiperda利用OS中的GOX蛋白来调节玉米的挥发性物质排放，为植食性昆虫的适应性进化及其与首选寄主植物的相互作用提供了新的观点。
