Fluorescent Pseudomonas spp. from suppressive and conducive soils share genomic and functional traits relevant to Fusarium graminearum disease suppression.

ABSTRACT:

Background

Soils suppressive to fungal pathogens harbor microbiomes that can inhibit disease development despite the presence of virulent pathogens and susceptible hosts. Fluorescent Pseudomonas are often implicated in such suppressiveness, but their genomic determinants and distribution in suppressive vs. non-suppressive (i.e., conducive) soils remain unclear.

Results

We investigated the taxonomic and functional diversity of Pseudomonas populations from wheat rhizospheres in four agricultural soils with contrasting suppressiveness to Fusarium graminearum-induced seedling disease. rpoD-based metabarcoding and culture-dependent isolation revealed distinct Pseudomonas community structures linked to soil suppressiveness. However, major phylogenetic groups were shared across soi
