Dual expression of plastidial GPAT1 and LPAT1 regulates triacylglycerol production and the fatty acid profile in Phaeodactylum tricornutum

Table 1 Specific growth rate, biomass and lipid productivity of overexpression lines (OE-1 and OE-2) and wild-type (WT)

Content	Strains
Content	WT	OE-1	OE-2
Specific growth rate (μ)^a	0.542 ± 0.069	0.772 ± 0.093**	0.785 ± 0.078**
Biomass (DCW, g L⁻¹)	1.284 ± 0.132	1.671 ± 0.151**	1.664 ± 0.177**
Total lipid productivity (mg day⁻¹ 10⁹ cells⁻¹)	1.023 ± 0.071	2.737 ± 0.195**	2.779 ± 0.209**
TAG productivity (mg day⁻¹ 10⁹ cells⁻¹)	0.689 ± 0.053	1.953 ± 0.142**	2.037 ± 0.139**

^aDetermined in the log phase. Specific growth rate and biomass were measured on day 4 while total lipid productivity and TAG productivity were determined on day 7. Each value represents the mean ± SD (n = 3). A significant difference between WT and OE lines is indicated at the p < 0.05 (*) or p < 0.01 (**) level
