Fig. 2From: Genome-wide expression profiles of Pyropia haitanensis in response to osmotic stress by using deep sequencing technologyExpression graphs of subclusters identified by the hierarchical cluster analysis. Ten subclusters represent expression signatures of 3,569 differentially expressed genes of Py. haitanensis using four different treatments. The x-axis represents the treatments. The y-axis represents the value of the relative expression level [log2 (ratio)]. The gray line represents the value of the relative expression level, the blue line represents the mean value of the relative expression level, and the red line is the referenceBack to article page
