The effect of disruption of acyl-CoA thioesterase gene (ptTES1) on the acyl-CoA pool of P. tricornutum. Acyl-CoA profile (a) and total acyl-CoA concentrations (b) of Pt_WT and ptTES1 knockout line Tes-KO cultures grown in nitrogen-deprived F/2 medium for 72 h. Values are the average of three experiments (± SD). Asterisks indicate statistically significant differences from WT based on Student’s t test (*P < 0.05)
