Assembly V4.0: The A. mexicanum transcriptome has been deep sequenced (15,000,000 Roche 454 short sequence reads and 50K Sanger reads) and assembled. The resulting assembly V4.0 can now be BLAST searched here. Approximately 89.9% of the 14 million high quality sequences were assembled into contigs with a total length of 542 Mb.

Salamanders in Research


Salamanders have served as model organisms for more than a century. A majority of the earliest embryological and morphological analyses of vertebrate development were conducted using salamander embryos. Today, salamanders continue to be the best animal models for several areas of research and a new generation of researchers are adopting salamanders – and in particular the Mexican axolotl - as their primary animal model.  This webpage provides links to projects that are developing genomic and genetic resources to enhance the axolotl model.

Fun Facts

What determines whether an axolotl will grow up to be male or female?

Axolotls have genetic sex-determination - a locus on an axolotl chromosome determines whether an axolotl is male or female.

In salamanders, the sex determining mechanism is referred to as ZZ/ZW and the heterogametic sex is female.
