Fig. 2From: Organism-environment interactions and differential gene expression patterns among open-coastal and estuarine populations of Porphyra umbilicalis Kützing (Rhodophyta) in the Northwest AtlanticHeat map showing expression levels of a select number of contigs within the RNA-seq libraries annotated as GO:0055114, oxidation-reduction process. The gray dotted center line represents mean expression. Yellow to white shades represent expression above the mean; orange to red shades represent expression below the mean. A heat map showing the expression levels of all contigs annotated as GO:0055114 is provided as Additional file 1Back to article page
