Summary Ester‐linked p‐coumarate (pCA) is a hallmark feature of the secondary cell walls in commelinid monocot plants. It has been shown that pCA groups arise during lignin polymerisation from the participation of monolignol conjugates assembled by p‐coumaroyl‐CoA:monolignol transferase (PMT) enzyme...
