Abstract
The Melipona gut microbes differ from other social bees, with the absence of crucial corbiculate core gut symbionts and the high occurrence of environmental strains. We studied the microbial diversity and composition of three Melipona species and their honey to understand which strains are obtained by horizontal transmission (HT) from the pollination environment; or represent symbionts co-evolved with Melipona by HT from the hive/food stores or vertical transmission (VT) via social interactions. Bees harbored higher microbial alpha diversity and a different and more species-specific bacterial composition than honey. Otherwise, the fungal communities of bee and honey samples are less dissimilar. As expected, the core symbionts Snodgrassella and Gilliamella were absent in bees that had a prevalence of Lactobacillus Firm-5, environmental Lactobacillaceae, Bifidobacteriaceae and Acetobacteraceae. Also, Pectinatus and Floricoccus have habitat preferences for bees, putatively representing novel symbionts from the environment that co-evolved via VT among generations. Fructilactobacillus found in bees possibly had HT to bees from honey stores. Metschnikowia yeasts, consistent in all bees and honey samples, might have HT to bees from food stores. Similarly, Saccharomycetales might have HT from honey or plants/flowers to bees. This work contributes to the understanding of Melipona symbionts and their modes of transmission.
期刊介绍:
FEMS Microbiology Ecology aims to ensure efficient publication of high-quality papers that are original and provide a significant contribution to the understanding of microbial ecology. The journal contains Research Articles and MiniReviews on fundamental aspects of the ecology of microorganisms in natural soil, aquatic and atmospheric habitats, including extreme environments, and in artificial or managed environments. Research papers on pure cultures and in the areas of plant pathology and medical, food or veterinary microbiology will be published where they provide valuable generic information on microbial ecology. Papers can deal with culturable and non-culturable forms of any type of microorganism: bacteria, archaea, filamentous fungi, yeasts, protozoa, cyanobacteria, algae or viruses. In addition, the journal will publish Perspectives, Current Opinion and Controversy Articles, Commentaries and Letters to the Editor on topical issues in microbial ecology.
