Other claims from this paper (11)
- Observation VdEGe1 of Verticillium dahliae was classified into glycoside hydrolase family 45 (GH45).
- Intervention effect Host-induced gene silencing of VdEGe1 significantly reduced Verticillium wilt symptoms, disease index and fungal biomass in infected cotton.
- Intervention effect The VdEGe1 knockout mutant of V. dahliae showed impaired colony expansion and hyphal growth.
- Intervention effect The VdEGe1 knockout mutant of V. dahliae showed impaired sporulation and spore germination.
- Intervention effect The VdEGe1 knockout mutant of V. dahliae had severely attenuated virulence.
- Observation VdEGe1 was confirmed to be a secreted protein.
- Intervention effect VdEGe1 did not trigger or suppress cell death in Nicotiana benthamiana.
- Observation Secretome analysis identified 311 differentially expressed secretory proteins.
- Observation Of the differentially expressed secretory proteins, 156 were down-regulated.
- Intervention effect The VdEGe1 deletion mutant showed significant down-regulation of mitochondrial-related proteins and several carbohydrate-active enzymes.
- Intervention effect The VdEGe1 deletion mutant had decreased intracellular ATP levels and slower growth on media with various carbon sources.
