The core gut microbiome of adult honeybee comprises a set of recurring bacterial phylotypes, accompanied by lineage-specific, variable, and less abundant environmental bacterial phylotypes. Several mutual interactions and functional services to the host, including the support provided for growth, hormonal signaling, and behavior, are attributed to the core and lineage-specific taxa. By contrast, the diversity and distribution of the minor environmental phylotypes and fungal members in the gut remain overlooked. In the present study, we hypothesized that the microbial components of forager honeybees (i.e., core bacteria, minor environmental phylotypes, and fungal members) are compartmentalized along the gut portions. The diversity and distribution of such three microbial components were investigated in the context of the physico-chemical conditions of different gut compartments. We observed that changes in the distribution and abundance of microbial components in the gut are consistently compartment-specific for all the three microbial components, indicating that the ecological and physiological interactions among the host and microbiome vary with changing physico-chemical and metabolic conditions of the gut.

成年蜜蜂肠道细菌和真菌微生物组的区室化



成年蜜蜂的核心肠道微生物组由一组重复出现的细菌系统型组成,伴随着谱系特异性的、可变的和较少丰富的环境细菌系统型。一些相互相互作用和对宿主的功能服务,包括为生长、激素信号和行为提供的支持,都归因于核心和谱系特定的分类群。相比之下,肠道中次要环境系统型和真菌成员的多样性和分布仍然被忽视。在本研究中,我们假设采集蜜蜂的微生物成分(即核心细菌、次要环境系统发育型和真菌成员)沿着肠道部分划分。在不同肠道区室的理化条件下研究了这三种微生物成分的多样性和分布。我们观察到,肠道中微生物成分的分布和丰度的变化对于所有三种微生物成分来说始终是区室特异性的,这表明宿主和微生物组之间的生态和生理相互作用随着肠道的物理化学和代谢条件的变化而变化。肠道。
