From: Cloning of a novel endogenous promoter for foreign gene expression in Phaeodactylum tricornutum
Cell growth (filled triangle) and relative eGFP fluorescence (filled square) of P. tricornutum transformed with the construct containing fcpA (A), CIP1 (B), GLNA-501 (C), and GLNA-997 promoter (D); statistical analysis on the eGFP expression level of each promoter at Day 6 (E) and Day 11 (F). Each transformed P. tricornutum was seeded with the concentration of 105 cell/mL at the day 0 and cultivated. Cell density and eGFP expression were evaluated daily. The values were expressed as mean ± SD of three independent experiments. Statistical analysis was performed using ANOVA followed by the Tukey’s test for multiple comparison at p < 0.05. a, b, c, and d indicate statistically significant differences on eGFP expression level of fcpA, CIP1, GLNA-501, and GLNA-997-driven constructs at Day 6 and Day 11
