Characterization of a Hypovirus-Regulated Septin Cdc11 Ortholog, CpSep1, from the Chestnut Blight Fungus Cryphonectria parasitica.
Molecular Plant-microbe Interactions : MPMI 2018 August 23
We identified a protein spot showing down-regulation in the presence of Cryphonectria hypovirus 1 (CHV1) and tannic acid supplementation as a septin subunit with the highest homology to the Aspergillus nidulans aspA gene, an ortholog of the Saccharomyces cerevisiae Cdc11 gene. To analyze the functional role of this septin component (CpSep1), we constructed its null mutant and obtained a total of eight CpSep1-null mutants from 137 transformants. All CpSep1-null mutants showed retarded growth with fewer aerial mycelia and intense pigmentation on PDAmb plates. When the marginal hyphae were examined, hyper-branching was observed in contrast to the wild type. The inhibition of colonial growth was partially recovered when the CpSep1-null mutants were cultured in the presence of the osmostabilizing sorbitol. Conidia production of the CpSep1-null mutants was significantly increased by at least 10-fold more. Interestingly, the conidial morphology of the CpSep1-null mutants changed to circular in contrast to the typical rod-shaped spores of the wild type, indicating a role of septin in the spore morphology of C. parasitica. However, no differences in the germination process were observed. Virulence assays using excised chestnut bark, stromal formation on chestnut stems, and apple inoculation indicated that the CpSep1 gene is important in pathogenicity.
