Introduction

Genomics is  currently undergoing a revolution brought about by the advent of  high-throughput parallel sequencing and powerful cytogenetic techniques such as fluorescent in-situ hybridization (FISH) and comparative genomic  hybridization (CGH). This has opened new opportunities to study non-model organisms, such as reptiles and amphibians, in ways that were  previously restricted to human and mouse.

Of special interest to our lab is the comparative genomics of sex determination in reptiles.  Sex determination has been a topic of speculation and rigorous inquiry  since the time of Aristotle, and remains a hot topic today because of  its intrinsic interest as a fundamental biological process, and because greater understanding brings benefit for human health. Our team at the University of Canberra is using frontier DNA technologies to probe  the astonishingly diverse mechanisms of sex determination in reptiles.

As  part of this research, we have collaborated with the Beijing Genome  Institute (BGI, Shenzhen) to generate an annotated genome for the  Australian central bearded dragon Pogona vitticeps. The annotated genome is complete, published in GigaScience, and a dense physical mapping of the genome is now also available through BMC Genomics. The resource includes a BAC library available commercially from Amplicon Express and a series of transcriptomes from a range of tissues.
