Fig. 2From: Physiochemical and molecular responses of the diatom Phaeodactylum tricornutum to illumination transitionsPigment profiles of P. tricornutum during the two-stage treatment. A Heatmap shows the log2(fold change) values of β-carotene, fucoxanthin, diatoxanthin (Dtx), diadinoxanthin (Ddx), pool of Dtx and Ddx (Dtx + Ddx), and ratio of Dtx/(Dtx + Ddx). B β-carotene, fucoxanthin, diatoxanthin (Dtx), diadinoxanthin (Ddx), pool of Dtx and Ddx (Dtx + Ddx), and ratio of Dtx/(Dtx + Ddx) of day 3 cultures for CT, HL, HLC and HLR. The significant difference is designated by * (p < 0.05) or ** (p < 0.01) under Student’s t-testBack to article page
