Laccases were proposed for lignin biosynthesis and for phenolic production. However, currently there are no reports of laccase functions on the monolignol polymerization in trees. We have identified 20 xylem-expressed laccases among the 79 laccase gene models in the P. trichcarpa genome. To study which laccases are involved in wood formation, we produced transgenics overexpressing Ptr-miR397a, which is predicted to target laccases. Our preliminary qRT-PCR showed gene expression reductions of selected six laccase genes, indicating successful functioning of Ptr-miR397a in the transgenic plants. We propose to characterize the transgenic plants for transcriptome and sugar composition analysis, including lignin content, lignin S/G ratio, and phenolic content. Correlation of the transcriptome and sugar composition changes will enable us to identify the laccases responsible for wood formation.
