Fig. 3: Specificity of gene expression at the level of tissues and cells.
From: Evolution of chemosensory tissues and cells across ecologically diverse Drosophilids

A Single cell atlases from D. melanogaster antenna legs and proboscis. Colors highlight the same cell types of interest across tissues. B Density plots for differentially and non-differentially expressed genes (leftmost panel) relative to expression specificity for tissues (top) and cell types (bottom). Colored circles with lines above the density plots indicate the expression specificity values of three genes (Or56a, sosie and rho) chosen to illustrate the varying relationships between expression specificity at the level of tissues and cells. Expression of the three genes has been mapped onto the D. melanogaster cell atlases (right three panels). C Density plots for old and young genes relative to expression specificity for tissues (top left) and cell types (bottom left). The middle left density plot shows the distribution of expression specificity values for genes grouped by duplication levels (2 = paralog group size of 2, 3–4 = paralog group size of 3–4, >4 = paralog group size greater than 4). Colored circles with lines above the density plots indicate the expression specificity values of five genes (Or43b, Qsox4 and Gr36c/Gr98d/Gr10b) chosen to illustrate varying relationships between expression specificity at the level of tissues and cells (see text). Expression of the five genes has been mapped onto the D. melanogaster cell atlases (right three panels). Location of source data for this figure can be found in “Source_data.xlsx”.
