Despite the lack of updates, things have been happening!
After our discovery of extremely low genetic diversity in the Sb variant of the fire ant social chromosome, we asked what is going on with Gp-9? This is the original odorant binding protein that Ken Ross found - using starch gel electrophoresis - to be fully associated with single vs multiple-queen colonies.
The patterns described back then still hold, but surprisingly we find that nine additional Gp-9-like odorant binding protein genes are in the social chromosome region of suppressed recombination. The descriptions of all 23 fire ant Odorant Binding Proteins, their expression profiles, and the differences between social chromosome alleles are detailed in Evolution Letters:
In a different paper, we review findings from the most recent analyses of the 23 ant genomes and 38 ant transcriptomes.
Lab members had the opportunity to present at many occassions, including:
Finally, we congratulate Gino Brignoli & Abdoulie Kanteh for the high marks achieved for their MSc disserations, and Roddy Pracana for submitting his PhD:
