Analysis of triacylglycerols from P. tricornutum wild type and the Tes-KO mutant grown in nitrogen-replete F/2 media for 8 days. Change of the molecular species composition of TAG (a), fatty acid distribution in TAG (b), the distribution of fatty acids at sn-2 (c) and sn-1 + 3 positions (d) of TAG in P. tricornutum strains. Data are the means of three experimental replicates with SD. Asterisks indicate statistically significant differences from WT based on Student’s t test (*P < 0.05, **P < 0.01). TAG triacylglycerol
