How do duplicated receptor genes "find a home" in olfactory circuits? Great study by the Arguello lab shows the re-coding of olfactory channels across species. Neat combination of phylogenetic reconstruction, sc-transcriptomics and more. Check out the pre-print: www.biorxiv.org/content/10.6...
Odorant receptors ( Or s) are the interface between an animal’s nervous system and its olfactory environment. In insect genomes, the Or s are often the largest gene family, and their rapid duplication...
