Total lipid content of overexpression lines (OE1 and OE2) and wild-type (WT) under normal condition (Normal) and cells subjected to 48 h of N (-N) or P (-P) deprivation. Cells were harvested on day 7 and subsequently placed into nutrient-replete and depleted media for 48 h of culture, respectively. a Total lipid content per liter of algal culture; b total lipid content per 109 algal cells; c total lipid content per mg dry weight; d, triacylglycerol (TAG) content per liter of algal culture; e TAG content per 109 algal cells; f TAG content per mg dry weight. A significant difference between WT and OE lines is indicated at the p < 0.05 (*) or p < 0.01 (**) level. Each value represents the mean ± SD (n = 3)
