花蜜是一种含糖的水溶液，是植物提供给动物互惠互利者的回报。由于花蜜营养丰富，它们通常含有重要的微生物群落，这些微生物群落可能是致病的，良性的，甚至有时对植物健康有益。通过最近的进展，现在很清楚，这些微生物改变花蜜化学，这反过来又影响互利主义行为（例如传粉者访问）。为了抵抗不必要的微生物生长，花蜜通常含有抗微生物化合物，特别是蛋白质，专门的（次级）代谢物和金属的形式。这篇综述涵盖了我们目前对花蜜抗菌剂的了解，以及它们与微生物和昆虫访客的相互作用。
Nectar is a sugary, aqueous solution that plants offer as a reward to animal mutualists for visitation. Since nectars are so nutrient-rich, they often harbor significant microbial communities, which can be pathogenic, benign, or even sometimes beneficial to plant fitness. Through recent advances, it is now clear that these microbes alter nectar chemistry, which in turn influences mutualist behavior (e.g. pollinator visitation). To counteract unwanted microbial growth, nectars often contain antimicrobial compounds, especially in the form of proteins, specialized (secondary) metabolites, and metals. This review covers our current understanding of nectar antimicrobials, as well as their interplay with both microbes and insect visitors.
