TAG content and composition in yeast cultures in response to expression of LiDGATs and feeding with exogenous FAs. a Levels of TAG extracted from yeast expressing empty vector (EV), LiDGAT1, LiDGAT2.1, LiDGAT2.2 and LiDGAT2.3 shown as fatty acids esterified to TAG over total fatty acids (TFA). The cultures were grown in absence (black box) or presence of exogenous 18:2 (light grey bars), 18:3n-6 (white bars) or 20:4 (dark grey bars). b-e FA profiles of TAG extracted from H1246 transformants showed on (a). For all experiments values represent mean ± SD (n = 3). Raw data for TAG content and FA composition are given in Additional file 12
