Research Abstract |
The author characterized a newly identified transcription factor gene from poplargenome. The gene is preferentially expressed in a secondary developing xylem in poplar. Fusing the transcription factor with a VP16 transcriptional activation domain and with a SRDX transcriptional repression domain changed the transcriptional activity. The overexpression of the chimeric transcription factors changed leaf morphology. In addition, the overexpression significantly up-regulated lignocellulose biosynthetic genes, and caused significant change of cell wall components in the transgenic aspen leaves.
