| 英文摘要 | Secondary cell wall (SCW) formation is regulated by a multilevel transcriptional regulatory network, in which MYB transcription factors (TFs) play key roles. In woody plants, hundreds of MYB TFs have been identified, most of which have unknown functions in wood SCW biosynthesis. Here, we characterized the function of a Populus MYB gene, PtoMYB10. PtoMYB10 was found to encode an R2R3-MYB TF and exhibit dominant expression in xylem tissues. PtoMYB10 was determined to be located in the nucleus with the ability to activate transcription. Overexpression of PtoMYB10 in Populus resulted in a drastic increase in SCW thickening in xylem fiber cells as well as ectopic deposition of lignin in cortex cells. The expression of genes associated with lignin biosynthesis was induced in PtoMYB10 overexpressing plants, whereas repressed gene expression was found with the anthocyanin biosynthesis pathway. Lignin and anthocyanin are both produced from metabolites of the phe-nylpropanoid pathway. Accordingly, the anthocyanin content of Populus overexpressing PtoMYB10 decreased by more than 68%. These results indicate that PtoMYB10 can positively regulate xylary fiber SCW thickening, accompanied by the reprogramming of phenylpropanoid metabolism, which redirects metabolic flux from anthocyanin biosynthesis to monolignol biosynthesis. |
