ROOMIE1 in Lotus japonicus controls rhizosphere microbiome composition, with natural haplotypes showing standing variation locally and disruption reproducibly shifting community makeup.
- Why it matters: Plant genetic loci shaping root-associated microbes are not well understood, especially how their population-genomic patterns differ from climate-linked selection.
- What they did: The study inoculated 155 L. japonicus accessions with a synthetic community of 107 bacterial isolates, mapped 355 microbiome-associated QTL, then functionally tested ROOMIE1 via mutations and natural alleles in synthetic communities and native soil.
- The result: Microbiome-associated loci showed heterogeneous signatures, including strong regional differentiation and low differentiation with multiple haplotypes; ROOMIE1 disruption altered rhizosphere composition in both settings and its haplotypes were linked to microbiome differences among closely related accessions.
