Title: A highly conserved effector in Fusarium oxysporum is required for full virulence on Arabidopsis Thatcher LF, Gardiner DM, Kazan K, Manners JM Ref: Mol Plant Microbe Interact, 25:180, 2012 : PubMed
Secreted-in-xylem (SIX) proteins of the vascular wilt pathogen Fusarium oxysporum f. sp. lycopersici are secreted during infection of tomato and function in virulence or avirulence. F. oxysporum formae speciales have specific host ranges but the roles of SIX proteins in diverse hosts are unknown. We identified homologs of F. oxysporum f. sp. lycopersici SIX1, SIX4, SIX8, and SIX9 in the genome of Arabidopsis infecting isolate Fo5176. A SIX4 homolog (termed Fo5176-SIX4) differed from that of F. oxysporum f. sp. lycopersici (Fol-SIX4) by only two amino acids, and its expression was induced during infection of Arabidopsis. Transgenic Arabidopsis plants constitutively expressing Fo5176-SIX4 had increased disease symptoms with Fo5176. Conversely, Fo5176-SIX4 gene knock-out mutants (Deltasix4) had significantly reduced virulence on Arabidopsis, and this was associated with reduced fungal biomass and host jasmonate-mediated gene expression, the latter known to be essential for host symptom development. Full virulence was restored by complementation of Deltasix4 mutants with either Fo5176-SIX4 or Fol-SIX4. Thus, Fo5176-SIX4 contributes quantitatively to virulence on Arabidopsis whereas, in tomato, Fol-SIX4 acts in host specificity as both an avirulence protein and a suppressor of other race-specific resistances. The strong sequence conservation for SIX4 in F. oxysporum f. sp. lycopersici and Fo5176 suggests a recent common origin.
Fusarium species are among the most important phytopathogenic and toxigenic fungi. To understand the molecular underpinnings of pathogenicity in the genus Fusarium, we compared the genomes of three phenotypically diverse species: Fusarium graminearum, Fusarium verticillioides and Fusarium oxysporum f. sp. lycopersici. Our analysis revealed lineage-specific (LS) genomic regions in F. oxysporum that include four entire chromosomes and account for more than one-quarter of the genome. LS regions are rich in transposons and genes with distinct evolutionary profiles but related to pathogenicity, indicative of horizontal acquisition. Experimentally, we demonstrate the transfer of two LS chromosomes between strains of F. oxysporum, converting a non-pathogenic strain into a pathogen. Transfer of LS chromosomes between otherwise genetically isolated strains explains the polyphyletic origin of host specificity and the emergence of new pathogenic lineages in F. oxysporum. These findings put the evolution of fungal pathogenicity into a new perspective.
