RT Journal Article SR Electronic T1 Individual variation of natural D. melanogaster associated bacterial communities JF bioRxiv FD Cold Spring Harbor Laboratory SP 126912 DO 10.1101/126912 A1 Yun Wang A1 Fabian Staubach YR 2017 UL http://biorxiv.org/content/early/2017/04/12/126912.abstract AB D. melanogaster has become an important model organism to study host-microbe interaction. However, we still know little about the natural microbial communities that are associated with D. melanogaster. Especially, information on inter-individual variation is still lacking because most studies so far have used pooled material from several flies. Here, we collected bacterial 16S rRNA gene community profiles from a set of 32 individuals from a single population and compare the variation to that of samples collected from different substrates and locations. While community differences were on average larger between samples collected from different substrates, there was still a surprising amount of variation of microbial communities between individual flies. The samples clustered into two groups suggesting that there are yet unknown factors that affect the composition of natural fly associated microbial communities and need research.Importance D. melanogaster is an important model organism in evolutionary biology and also for the study of host-microbe interaction. In order to connect these to aspects of D. melanogaster biology, it is crucial to better understand the natural D. melanogaster microbiota because only the natural microbiota can affect the evolution of the host. We present, to our knowledge, the first data set that captures inter-individual variation of D. melanogaster associated bacterial communities. Clustering of communities into two larger groups suggests that there are important drivers of these communities that we do not understand yet suggesting in return that more research on the natural microbiota of D. melanogaster is needed.
