Natural variation in mouth-form transcriptomics. (A–D) Volcano plots of differentially expressed genes between pooled St- and Eu-biased strains of P. pacificus at four developmental time points. Significant genes (adjusted P-values < 0.05) upregulated in St are colored blue, and those upregulated in Eu are colored red. Gold points represent components of the mouth-form GRN, and significant mouth-form genes are labeled in gold on the plot. (E–N) Mean expression of normalized counts from DESeq2 for mouth-form genes in pooled St- and Eu-biased strains. (*) Time points with significant expression differences (adjusted P-value < 0.05).
