Parallel evolution of alternate morphotypes of Chryseobacterium gleum during experimental evolution with Caenorhabditis elegans.
Microbial evolution within polymicrobial communities is a complex process. Here, we report within-species diversification within multispecies microbial communities during experimental evolution with the nematode Caenorhabditis elegans. We describe morphological diversity in the target species Chryseobacterium gleum, which developed a novel colony morphotype in a small number of replicate communities. Alternate morphotypes coexisted with original morphotypes in communities, as well as in single-species experiments using evolved isolates. We found that the original and alternate morphotypes differed in motility and in spatial expansion in the presence of C. elegans. This study provides insight into the emergence and maintenance of intraspecies diversity in the context of microbial communities.
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.
- Application of ecological theory to microbial ecology
- Interactions and signalling between microorganisms and with plants and animals
- Interactions between microorganisms and their physicochemical enviornment
- Microbial aspects of biogeochemical cycles and processes
- Microbial community ecology
- Phylogenetic and functional diversity of microbial communities
- Evolutionary biology of microorganisms
