Mapping the crocodile genome
Dr Lee Miles, from the University of Sydney, worked with a team of Australian and international researchers to study a population of saltwater crocodiles from the Darwin Crocodile Farm in the Northern Territory. He said, "This map will be a valuable resource for crocodilian researchers, facilitating the systematic genome scans necessary for identifying genes affecting complex traits of economic importance in the crocodile industry".
The researchers' map also provides a significant step towards the elucidation of the crocodilian genome, forming a scaffold for genome sequence assembly, and will be of intrinsic value to comparative mapping efforts aimed at understanding the molecular evolution of reptilian, as well as other amniote genomes. From an economic perspective, this new information should be able to assist in the breeding of farmed crocodiles with favourable growth rate, survival and skin quality by facilitating the systematic searches necessary to identify the genes that affect these traits.
