Gene Details:
- Gene ID: GWHPAAYT014255
- Gene Symbol: PbbZIP4
- Gene Name:
- Genome:
- Species: Pyrus betulifolia
Functional Descriptions:
- Transcription factor PbbZIP4 is targeted for proteasome-mediated degradation by the ubiquitin ligase PbATL18 to influence pear’s resistance to Colletotrichum fructicola by regulating the expression of PbNPR3.
- Found that an E3 ubiquitin ligase, PbATL18, interacts with and ubiquitinates the transcription factor PbbZIP4, and this process is enhanced by C. fructicola infection.
- Silencing PbATL18 and PbbZIP4 in Pyrus betulaefolia seedlings resulted in opposite effects, with PbbZIP4 silencing enhancing resistance to C. fructicola infection and PbATL18 silencing increasing sensitivity to C. fructicola infection.
- PbbZIP4 was ubiquitinated by PbATL18 and degraded by the 26S proteasome, which decreased the expression of PbNPR3 and promoted SA signal transduction, thereby enhancing plant C. fructicola resistance.
