Gut Microbial Community

Research into the microbial community within the human gastrointestinal tract (GIT) has developed from investigating micro-organisms that cause disease to trying to establish those that are important to maintain health. Thus we are now at a point where the bacterial community in healthy individuals has been well characterized, emphasizing the huge interindividual variation that exists. Molecular advances have also facilitated initial studies on establishing the composition of the viral and eukaryotic communities. In this article, we provide an overview of the current state of knowledge, illustrating the structure and function of the gut microbial community.

AbstractPlants alter chemical and physical properties of soil, and thereby influence rhizosphere microbial community structure. The structure of microbial communities may in turn affect plant performance. Yet, outside of simple systems with pairwise interacting partners, the plant genetic pathways that influence microbial community structure remain largely unknown, as are the performance feedbacks of microbial communities selected by the host plant genotype. We investigated the role of the plant circadian clock in shaping rhizosphere community structure and function. We performed 16S rRNA gene sequencing to characterize rhizosphere bacterial communities of Arabidopsis thaliana between day and night time points, and tested for differences in community structure between wild-type (Ws) vs. clock mutant (toc1-21, ztl-30) genotypes. We then characterized microbial community function, by growing wild-type plants in soils with an overstory history of Ws, toc1-21 or ztl-30 and measuring plant performance. We observed that rhizosphere community structure varied between day and night time points, and clock misfunction significantly altered rhizosphere communities. Finally, wild-type plants germinated earlier and were larger when inoculated with soils having an overstory history of wild-type in comparison to clock mutant genotypes. Our findings suggest the circadian clock of the plant host influences rhizosphere community structure and function.
