Effects of light intensity on crtE and crtB expression levels in E. gracilis. a Time-course of cell concentration of E. gracilis grown under continuous light at 27, 55, 460, and 920 μmol m−2 s−1 at 25 °C. b Cells of the alga cultured under the indicated light-stress treatments for 7 days. c and d Expression levels of EgcrtE (c) and EgcrtB (d) in the algal cells treated with the 7-day light-stress treatments. Data are the mean ± SE (n = 3). Data are representative of at least two individual experiments with similar results. Bars labeled with the same letter are not significantly different (Tukey’s multiple range test, P < 0.05). n.s., not significant; *P < 0.05, t-test
