Compared with the wild type, the 4CL downregulated line showed significantly increased levels of p-hydroxycinnamic acids such as p-coumaric, ferulic, and sinapic acids. In contrast, the CAld5H upregulated line had increased content of p-coumaryl and 5-hydroxyconiferyl alcohols. In the 4CL downregulated line, it was likely that most hydroxycinnamic acids were glycosylated. These results strongly suggest that the downregulation of 4CL and upregulation of CAld5H disrupt the metabolic flow through the cinnamate/monolignol pathway and thus alter the amount and structure of its final product, lignin.}, number={1}, journal={JOURNAL OF WOOD SCIENCE}, author={Suzuki, Shiro and Sakakibara, Norikazu and Li, Laigeng and Umezawa, Toshiaki and Chiang, Vincent L.}, year={2010}, month={Feb}, pages={71–76} } @article{nakatsubo_li_hattori_lu_sakakibara_chiang_shimada_suzuki_umezawa_2008, title={Roles of 5-hydroxyconiferylaldehyde and caffeoyl CoA O-methyltransferases in monolignol biosynthesis in Carthamus tinctorius}, volume={41}, number={9-10}, journal={Cellulose Chemistry and Technology}, author={Nakatsubo, T. and Li, L. and Hattori, T. and Lu, S. and Sakakibara, N. and Chiang, V.
