Fig. 7From: The Cyprinodon variegatus genome reveals gene expression changes underlying differences in skull morphology among closely related speciesExpression of genes commonly used as molecular markers of osteoblast and osteoclast cells indicate that genes functioning in osteoblast differentiation are typically not differentially expressed among species of pupfish, while a number of osteoclast expressed genes tend to be overexpressed in the scale-biter and underexpressed in the durophage. Gene expression values were measured as log2 transformed RPKM similar to Fig. 6. Letters indicate significant differential expression (FDR ≤ 0.1) in pairwise comparisons at each stage. Letters are omitted from stages where no pairwise comparisons are significantBack to article page
