Title

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.

Genome-wide analysis of R2R3-MYB transcription factors in poplar and functional validation of PagMYB147 in defense against Melampsora magnusiana

Bin Wang; Chaowei Xiong; Zijia Peng; et al. Planta 2024. doi:10.1007/s00425-024-04458-3

Other claims from this paper (10)

Intervention effect Silencing of PagMYB147 exacerbated the severity of Mmag infection.
Mechanism The silencing effect likely reflects decreased ROS production and PAL enzyme activity.
Intervention effect Overexpression of PagMYB147 improved resistance to Mmag.
Intervention effect Overexpressing PagMYB147 gave ROS accumulation and PAL enzyme activity opposite to silencing.
Observation 191 putative R2R3-MYB genes were identified in the Populus trichocarpa genome.
Observation Twelve tandem duplication events were detected in poplar R2R3-MYB genes.
Observation 148 segmental duplication events were detected, with the latter likely the main contributor to the expansion of poplar R2R3-MYB genes.
Observation A phylogenetic analysis grouped poplar and Arabidopsis R2R3-MYBs into 33 subgroups.
Observation Multiple R2R3-MYB genes responded to Melampsora magnusiana (Mmag) in RNA-Seq data.
Observation The PagMYB147 encoded product was primarily localized to the cell nucleus.
