Forward genetics in Caenorhabditis elegans identified five kola genes whose mutations nearly completely abolish gut colonization by the commensal Lelliottia jeotgali.
- Why it matters: Gut commensal adherence depends on host genetic components, but the specific host factors required for microbiome colonization in vivo remain unclear.
- What they did: Using transgenic L. jeotgali expressing tdTomato, the authors screened C. elegans mutants and selected those with complete loss of colonization, identifying kola-1-5 and gly-5.
- The result: The screen yields uncharacterized kola-1-5 predicted to encode secreted or membrane-bound proteins and implicates gly-5 in O-linked glycosylation, enabling mapping of host adherence pathways.
