During the past year the UCSC team added 35 vertebrate assemblies to the Genome Browser (Table 1), including the premier releases of 20 species. In line with our focus on primates and other vertebrates, the group of newly introduced species features 4 primates (baboon, mouse lemur, squirrel monkey and tarsier), 12 additional mammals (alpaca, dolphin, ferret, hedgehog, kangaroo rat, manatee, megabat, rock hyrax, shrew, sloth, southern white rhinoceros and tree shrew) and 4 additional vertebrates (American alligator, Atlantic cod, budgerigar and coelacanth). Several of the new assemblies were added to support the generation of the 60-species Conservation track released in 2012 on the GRCm38/mm10 mouse assembly, and many of these were originally sequenced and assembled for the Mammalian Genome Project (11). We plan to release a preliminary Browser with a minimal annotation set on the new GRCh38/hg38 human assembly in late 2013 or early 2014. Beginning with this new release, the numeric portion of the UCSC human assembly version name will match the Genome Reference Consortium version number to reduce confusion.
