Fig. 1From: The effect of Wolbachia on gene expression in Drosophila paulistorum and its implications for symbiont-induced host speciationPrincipal component analysis (a) and heatmap (b) of expression data of the OR semispecies. The PCA is based on all Drosophila genes in the analysis, while the heatmap shows only DE genes. F: female, M: male, WT: wild type, GFR: gut flora restored, abd: abdomenBack to article page
