Other claims from this paper (5)
- Observation Closely related Pseudomonas fluorescens strains promoted Arabidopsis growth.
- Observation Some closely related Pseudomonas fluorescens strains caused disease in Arabidopsis.
- Association Genomic islands correlated with outcomes for plant health.
- Mechanism An island with lipopeptide biosynthesis and quorum sensing genes was required for pathogenesis.
- Observation Loci associated with pathogenic and commensal lifestyles were convergently gained and lost across lineages through homologous recombination.
