HFA-containing TAG synthesis pathways in Arabidopsis seeds. TAG synthesis is depicted by Kennedy pathways (green arrows) and PC-mediated pathways (red arrows). Arabidopsis genes are highlighted in yellow. Castor genes found to enhance HFA accumulation in Arabidopsis are highlighted in red. Numbers in circles are enzymatic steps targeted in this study. DAG(1) is de novo DAG. DAG(2) is initial rapid formation from PC-derived DAG [55]. DAG(3) is a bulk slowly turned over DAG pool. Dashed arrow indicates DAG(2) can be phase partitioned into DAG(3). FA numerical symbols: 18:1, oleic acid; 18:1OH, ricinoleic acid. Abbreviations: CoA, co-enzyme A; DAG, diacylglycerol; DGAT, diacylglycerol acyltransferase; FAE1, fatty acid elongase1; FAH12, oleate Δ12–hydroxylase; FAS, fatty acid synthesis; G3P, glycerol-3-phosphate; GPAT, glycerol-3-phosphate acyltransferase; LPA, lysophosphatidic acid; LPAT, lysophosphatidic acid acyltransferase; LPCAT, lysophosphatidylcholine acyltransferase; PA, phosphatidic acid; PAP, phosphatidic acid phosphatase; PC, phosphatidylcholine; PDAT, phospholipid:DAG acyltransferase; PDCT, PC:DAG cholinephosphotransferase; TAG, triacylglycerol
