Involved in the synthesis of aromatics of the suberin polymer. Specifically affects the accumulation of the ferulate constituent of suberin in roots and seeds, but has no effect on the content of p-coumarate or sinapate. (E)-feruloyl-CoA + 16-hydroxyhexadecanoate = 16-feruloyloxyhexadecanoate + CoA 16-hydroxypalmitic acid is the main acyl acceptor. Optimum pH is 7.5. Optimum temperature is 10 degrees Celsius. A number of isoforms are produced. According to EST sequences. Expressed in roots, seedlings, leaves, stems, flowers and siliques. Detected at the protein level in roots and in seed coats. Detected in seed coats in the inner layer of the outer integument at the beginning of the desiccation stage. Also expressed at the chalazal region as desiccation proceeds. Elimination of suberin-associated ester-linked ferulate. Altered permeability and sensitivity of seeds and roots to salt stress. Belongs to the plant acyltransferase family.
