Over-expression of transcription factor ARK1 gene leads to down-regulation of lignin synthesis related genes in hybrid poplar '717'.

ABSTRACT: Improving wood growth rate and wood quality are worthy goals in forest genetics and breeding research. The ARK1 gene is one member of the ARBORKNOX family in all plants, which play an essential role in the process of plant growth and development, but the mechanism associated with its gene network regulation is poorly investigated. In order to generate over-expression transgenic hybrid poplar, the agrobacterium-mediated transformation was used to obtain transgenic hybrid poplar '717' plants to provide insight into the function of the ARK1 gene in poplar. Moreover, the morphology of transgenic plants was observed, and transcriptome analysis was performed to explore the ARK1 gene function. The results showed that there were significant differences in pitch, stem diameter, petiole length, leaf
