Effects of suppressing EgcrtB on carotenoid content of E. gracilis cells. Cells were treated with (+) or without (−) EgcrtB-dsRNA and cultured for 7 days at 25 °C under continuous light at 55 μmol m−2 s−1. Non-electroporated cells (n) were used as the control. Levels of carotenoids per cell are expressed relative to total carotenoids in the non-electroporated cells. β, β-carotene; Neo, neoxanthin; Ddx, diadinoxanthin; Dtx, diatoxanthin. Error bars indicate ± SD of biological quadruplicates. Bars labeled with the same letter are not significantly different (Tukey’s multiple range test, P < 0.05)
