Expression of G-protein coupled receptors and kinases. (A) Relative expression of members of GPCR families defined in a previous study  across A. queenslandica developmental stages (red, high; blue, low). Stage enrichment of genes was estimated using Fisher’s exact test (p-values shown). (B) Gene contig with a cluster of 13 rhodopsin family GPCR genes (gene organization is indicated at the bottom). Reads mapping to the plus (black) and minus (blue) strands of this genomic locus in the four developmental stages are shown (reads normalized to 10 million, maximum peak height shown is 10 reads). A non-GPCR gene in the cluster is shown in gray. (C) Average normalized read counts for members of kinase classes defined in a previous study .
