摘      要：The key transcription factor gene PdP apE RF109 was cloned from Populus davidiana×*** ***(Pdpap),and after overexpression of P dP ap ERF109 in transformants,the gene functions in the resistance response to Fusarium oxysporum *** with the wild Pdpap,after inoculation with ***,the physiological and biochemical characteristics,including relative fresh weight,peroxidase activity,and the percentage of electrolyte leakage showed that,after overexpression of the PdPapERF109 gene,the transformants grew well and displayed significant resistance to *** *** comparing the reactive oxygen species scavenging capacity of Pdpap plants after pathogen infection,the P dPapERF109-overexpressing plants had significantly better reactive oxygen species scavenging ability than the wild *** analysis of plant morphology and various physiological and biochemical parameters showed that the overexpression of the P dpapERF109 gene significantly improved the resistance of Pdpap plants to *** root ***,increasing the expression of the homologous ERF109 gene can be an effective strategy to increase disease resistance in hybrid poplars.
