Identification and characterization of BAHD hydroxycinnamoyltransferases in the fern Neoblechnum brasiliense

Neoblechnum brasiliense, a leptosporangiate fern of the family Blechnaceae, is known to have a rich phenolic metabolism. Rosmarinic acid and blechnic acid B have been detected beside chlorogenic acid. As BAHD acyltransferases often are responsible for the formation of this kind of esters, for example, rosmarinic acid synthases or 4-coumaroyl-CoA:shikimic or quinic acid hydroxycinnamoyltransferases, nine coding sequences for BAHD acyltransferases were amplified from N. brasiliense and heterologou
