Extended compartmentalized lignin pathway model in B. distachyon. Conversion of p-coumaric acid to p-coumaroyl CoA by 4CL and diffusion flux D9 are necessary to explain label incorporation into H-lignin in experiments with labeled phenylalanine. Conversion of p-coumaric acid to caffeic acid by C3H and the diffusion flux D10 are necessary to explain label incorporation into ferulic acid in the same labeling experiments with phenylalanine. The metabolic channel in the ER compartment keeps some of the 13C-label from being diluted by the cytosol diffusion fluxes and permits preferential incorporation of phenylalanine and tyrosine in S- and G-lignin
