Decoding Secrets of the Platypus Genome (Now That's a Lot of Secrets)

An advance paper in Genome Biology, co-authored by Frank Grutzner (profiled last year in GT's "Tomorrow's PIs" special edition), looks at the evolution of the mammalian major histocompatibility complex using the genomes of monotremes, which include the duck-billed platypus. Their work found homology between chicken microchromosomes and the smallest monotreme chromosomes, as well as that the monotreme sex chromosome system is still evolving: segments of the monotreme MHC that are now on separate chromosomes, they concluded, must once have been on the same gene. If you can't wait for the finished paper, a provisional PDF can be found here.
