An Integrated Analysis of Molecular Acclimation to High Light in the Marine Diatom Phaeodactylum tricornutum
Figure 3
Regulation pattern of HL affected genes during the acclimation period.
The differentially regulated genes encode proteins involved in light sensing, antenna proteins, photoreceptors, components involved in oxidative photosynthesis, carbon metabolism, Calvin cycle and ROS scavenging systems after exposure to HL for 0.5 h, 3 h, 6 h, 12 h, 24 h and 48 h. The color code indicates expression values. Squares with a diagonal line inside indicate genes with an expression ratio (log2 transformed) greater than +/−0.5 that are not significantly regulated. Genes where at least one of the probes representing the genes were significantly regulated by >2-fold at least at one time point during the acclimation period, were included in the figure. The expression patterns of genes marked with an asterisk are chloroplast encoded. The scale on the right represents gene expression ratio values, log2 transformed.
