Perturbation of 4CL activity significantly impacts the lignin content of diverse plant species. InPopulus trichocarpa, two well-studied xylem-specific Ptr4CLs (Ptr4CL3 and Ptr4CL5) catalyze the CoA ligation of 4-coumaric acid to 4-coumaroyl-CoA and caffeic acid to caffeoyl-CoA. Subsequently, two 4-hydroxycinnamoyl-CoA:shikimic acid hydroxycinnamoyl transferases (PtrHCT1 and PtrHCT6) mediate the conversion of 4-coumaroyl-CoA to caffeoyl-CoA. Here, we show that the CoA ligation of 4-coumaric and caffeic acids is modulated by Ptr4CL/PtrHCT protein complexes. Downregulation ofPtrHCTsreduced Ptr4CL activities in the stem-differentiating xylem (SDX) of transgenicP. trichocarpa. The Ptr4CL/PtrHCT interactions were then validatedin vivousing biomolecular fluorescence complementation (BiFC) and protein pull-down assays inP. trichocarpaSDX extracts. Enzyme activity assays using recombinant proteins of Ptr4CL and PtrHCT showed elevated CoA ligation activity for Ptr4CL when supplemented with PtrHCT. Numerical analyses based on an evolutionary computation of the CoA ligation activity estimated the stoichiometry of the protein complex to consist of one Ptr4CL and two PtrHCTs, which was experimentally confirmed by chemical cross-linking using SDX plant protein extracts and recombinant proteins. Based on these results, we propose that Ptr4CL/PtrHCT complexes modulate the metabolic flux of CoA ligation for monolignol biosynthesis during wood formation inP. trichocarpa.}, journal={FRONTIERS IN PLANT SCIENCE}, author={Lin, Chien-Yuan and Sun, Yi and Song, Jina and Chen, Hsi-Chuan and Shi, Rui and Yang, Chenmin and Liu, Jie and Tunlaya-Anukit, Sermsawat and Liu, Baoguang and Loziuk, Philip L. and et al.}, year={2021}, month={Oct} }
