Compartmental model of the lignin pathway in Brachypodium. The two compartments cross-talk through diffusion fluxes (red arrows). Enzymatic reactions are marked in blue. Green arrows represent monolignol transport into the cell wall. The yellow arrows are effluxes towards wall-bound p-coumaric acid and ferulic acid. The coefficient R in expressions like \(RD_{1}\) represents the ratio of volumes of the cytosol and ER compartments (\(R\, = \,{r \mathord{\left/ {\vphantom {r {\left( {1\, - \,r} \right)}}} \right. \kern-0pt} {\left( {1\, - \,r} \right)}}\), where \(r\) is the portion of cytosol volume and \(1\, - \,r\) is the portion of ER volume with respect to the total volume). R is a multiplier in the rates of diffusion fluxes associated with the ER that accounts for the difference in volumes
