Fatty acid content of overexpression lines (OE1 and OE2) and wild-type (WT). a Total fatty acid (TFA) content in cells 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; b, d relative abundance of main fatty acids in sn-2 position of TAG in cells harvested on day 7; c relative abundance of total C16 and C18 fatty acids in sn-1/3 position of TAG in cells harvested on day 7; e relative abundance of main fatty acids in sn-1/3 position of TAG in cells harvested on day 7. C16 represents the sum of C16:0 and C16:1 while C18 represents the sum of C18:0, C18:1, C18:2 and C18:3. 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. Each value represents the mean ± SD (n = 3)
