Overexpression of an AP2/ERF family gene,BpERF13,in birch enhances cold tolerance through upregulating CBF genes and mitigating reactive oxygen species

The AP2/ERF(APETALA2/ethylene-responsive factor)family of transcription factors(TF)is involved in regulating biotic and abiotic stress responses in plants.To explore the role of AP2/ERFs in cold tolerance in woody plants,BpERF13 was cloned and characterized in Betula platyphylla(white birch),a species primarily found in Asia in temperate and boreal climates.Based on phylogenetic analysis,BpERF13 is a member of the IXb subfamily of ERFs.Using qRT-PCR,we found…查看全部>>
