Characterization and expression analysis of the WRKY gene family in moso bamboo.

ABSTRACT: The WRKY family of transcription factors (TFs) is one of the ten largest families of TFs in higher plants and has been implicated in multiple biological processes. Here, we identified 121 WRKY TFs in moso bamboo, including five novel members that were not annotated in the Phyllostachys edulis genomic database. Estimation of the divergence time of paralogous gene pairs revealed an important role of the recent whole-genome duplication in the expansion of the WRKY family. Expression analysis based on quantitative reverse-transcription polymerase chain reaction (qRT-PCR) data revealed that a large number of PheWRKY genes varied significantly under cold or drought stress treatments, which could be defined as abiotic stress-responsive genes. The overexpression of PheWRKY72-2 in Arabidopsis resul
