越来越多的证据表明，花和蜜蜂的微生物组之间存在很大的重叠，这表明花是微生物传播的中心。花卉传播是否是蜜蜂微生物组组装的主要驱动力，以及花卉来源的微生物的功能重要性是否塑造了蜜蜂觅食决策，这些都是尚未回答的有趣问题。我们认为，相互作用网络的属性，如嵌套性，连通性和模块性，以及专业化模式可以预测潜在的传播途径的微生物之间的主机。然而，植物和蜜蜂宿主的微生物过滤决定了实现的微生物生态位。在功能上，共享的花微生物可以通过提高营养质量、解毒和花粉分解来为蜜蜂提供益处。花卉微生物也可以改变花卉资源的吸引力。总之，这些机制可能会影响花-蜂相互作用网络的结构。
Growing evidence reveals strong overlap between microbiomes of flowers and bees, suggesting that flowers are hubs of microbial transmission. Whether floral transmission is the main driver of bee microbiome assembly, and whether functional importance of florally sourced microbes shapes bee foraging decisions are intriguing questions that remain unanswered. We suggest that interaction network properties, such as nestedness, connectedness, and modularity, as well as specialization patterns can predict potential transmission routes of microbes between hosts. Yet microbial filtering by plant and bee hosts determines realized microbial niches. Functionally, shared floral microbes can provide benefits for bees by enhancing nutritional quality, detoxification, and disintegration of pollen. Flower microbes can also alter the attractiveness of floral resources. Together, these mechanisms may affect the structure of the flower-bee interaction network.
