Cane toad genome and others

Does anyone know if this has been fully mapped out or how much has? on line searches for me yield more about mitochondrial DNA. Anyone know if xenopus is mapped out also?

I don't think there are any fully-sequenced amphibians or reptiles.

Aside from sequencing, there has undoubtedly been some mapping of Xenopus - by mapping, I mean location of genes on chromosomes, and sequences of individual genes.

For awhile there was a lot of buzz about sequencing X. tropicalis. A lot of developmental work occurs in Xenopus laevis, but genetically it's a mess because it is allotetraploid or pseudotetraploid (I'm not sure which is the correct word off hand, I've heard both). So, there isn't a strong push to sequence it, although it's well studied. Some people would like to switch to X.tropicalis which grows faster and has traditional diploid genome, which makes genetics much easier. Much of the developmental work is expected to translate well from laevis to tropicalis as well. I know that they were sequencing it. I don't know where it is at at this point. I found this website, which you may find helpful.

Was reading this story and I thought of this thread.

Scientists Report First Genome Sequence of Frog: Genome of Xenopus Tropicalis Will Advance Frog Genetics

ScienceDaily (Apr. 29, 2010) — A team of scientists led by the Department of Energy's Joint Genome Institute (JGI) and the University of California, Berkeley, is publishing the first genome sequence of an amphibian, the African clawed frog Xenopus tropicalis, filling in a major gap among the vertebrates sequenced to date....

There has been some recent study of the Chaunus [Rhinella] marinus group using genetics and studying all of the species and major populations included in the group. Probably not what you're looking for, but interesting from a systematic point of view. Available from the CNAH pdf library.
