WRKY transcription factors are key regulators that activate and fine-tune stress responses, including defense responses against pathogens. We isolated a poplar (Populus tremulaxPopulus alba) cDNA sequence, PtWRKY23, that encodes the ortholog of Arabidopsis WRKY23 and present the functional analysis of WRKY23, with emphasis on its potential role in resistance to rust infection. To investigate the function of PtWRKY23, we examined PtWRKY23 expression after stress treatments by qRT-PCR and gener...Expand abstract
