Figure 1From: Antennal transcriptome profiles of anopheline mosquitoes reveal human host olfactory specialization in Anopheles gambiaeChemosensory gene repertoires of An. gambiae and An. quadriannulatus . The numbers of An. gambiae and An. quadriannulatus chemosensory genes annotated in this study (ovals). The estimated numbers of chemosensory genes in the most recent common ancestor (MRCA) of the two species (boxes). The numbers along vertical arrows indicate the estimated numbers of gene gain (+) and loss (-) events. The red and blue schematic arrows indicate the host preferences (red: anthropophagic, blue: zoophagic) of An. gambiae and An. quadriannulatus.Back to article page
