Interaction of the transcription factor PsERF117 with PR10.18 regulates the rust resistance in poplar

Chaowei Xiong; Xinye Liu; Zhongdong Yu Industrial Crops and Products 2026. doi:10.1016/j.indcrop.2026.122769

Other claims from this paper (10)

Observation Thirteen defense-associated gene families were identified.
Observation Members of 17 pathogenesis-related gene families were identified.
Method / resource WGCNA identified networks involving ERF and WRKY transcription factors.
Mechanism PsERF117 binds the PsPR10.18 promoter GCC-box and activates expression.
Mechanism Reduced PR10.18 expression may impair RNase activity and decrease rust resistance.
Intervention effect PsERF117 knockout weakened the hypersensitive response in P. szechuanica.
Intervention effect PsERF117 knockout reduced reactive oxygen species production in P. szechuanica.
Mechanism PsERF117 upregulates other defense genes to enhance poplar resistance.
Association Rust infection induced PsERF117 transcription.
Mechanism PsERF117 promotes expression of DOX1, 4CL2, and WRKY83.
