Transcriptional profile of enzymes potentially involved in hydroxy fatty acid (HFA) accumulation in R. communis. Expression levels of fatty acid hydroxylase (FAH) are compared with its close homolog, fatty acid desaturase (FAD2). The expressed sequence tag (EST) levels for enzymes potentially involved in removal of ricinoleate from phosphatidylcholine (PC) are compared between R. communis and B. napus. Asterisk indicates that EST levels for members of the same gene-family were summed. LPCAT, lysophosphatidylcholine acyltransferase; PLA2, phospholipase A2; PDCT/ROD1, phosphatidylcholine:diacylglycerol cholinephosphotransferase; DAG-CPT, diacylglycerol cholinephosphotransferase; PDAT, phospholipid/glycerol acyltransferase; PLC, phospholipase C; PLD, phospholipase D; FFA, free fatty acid; DAG, diacylglycerol; TAG, triacylglycerol; PA, phosphatidic acid.
