UvWSC1(1-113) from Ustilaginoidea virens triggers OsCPK13-dependent cell death and broad-spectrum resistance in rice, linked to SOBIR1-OsCPK13 signaling.
- Why it matters: Pathogens secrete many uncharacterized proteins, but which secreted factors both promote infection and activate host immunity is unclear.
- What they did: The study tested UvWSC1 and its minimal epitope UvWSC1(1-113) for immunogenicity in multiple plant species, then used rice genetics to assess roles of OsCPK13 and SOBIR1.
- The result: UvWSC1 knockout or overexpression attenuated fungal pathogenicity, and heterologous expression in rice conferred broad-spectrum resistance while activating basal immunity via OsCPK13 and SOBIR1, with UvWSC1(1-113) enhancing OsCPK13–OsSOBIR1 interaction.
