摘要:

植食性昆虫的口腔分泌物是昆虫取食时沉积在植物组织上的有机和无机溶质以及酶等复杂的混合物。昆虫口腔分泌物中特定成分已被证明在分子水平上具有调控植物-昆虫相互作用的重要功能。在这篇综述中,我们搜集了关于昆虫口腔分泌物的生物化学研究,并对目前已知的组分进行总结。其次,我们不仅概括了昆虫口腔分泌物已知组分的功能研究,还重点关注了这些组分在植物中特定的分子靶标。最后,我们强调了在昆虫生理学背景下研究昆虫口腔分泌物组分的重要性,这可能有助于揭示一些多功能分子化合物的潜在进化轨迹。

Abstract:

The oral secretions of insect herbivores are complex mixtures of organic and inorganic solutes and enzymes that are deposited onto plant tissues during the feeding process.  Some specific components of insect oral secretions have been shown to confer important functions in mediating plant–insect interactions at the molecular level.  In this review, we examined the biochemical studies of insect oral secretions to summarize the current knowledge of their compositions.  We then moved beyond the functional studies of components of oral secretions, and focused on the literature that pinpointed specific molecular targets of these compounds.  Finally, we highlighted the investigations of oral secretion components in the context of insect physiology, which shed light on the potential evolutionary trajectory of these multi-functional molecules.
