Fig. 3.
Cluster-wise (I–V) expression of differentially expressed (P ≤ 10−5) genes across samples. For each cluster gene expression patterns across all samples are shown. Gray lines depict expression levels of all genes, while the blue line indicates average gene expression of all genes in each cluster. Genes overexpressed in the foot were primarily grouped in cluster I. Cluster II and III are moderately and extremely differentially expressed mantle clusters, respectively. Similarly, genes overexpressed in the radula were split into one moderately overexpressed cluster IV and one extremely overexpressed cluster V.
