The tammar wallaby genome and transcriptome

The tammar wallaby (Macropus eugenii) is a kangaroo species native to islands lying near the coasts of Western and South Australia, as well as to small pockets of the mainland. The tammar is considered to be a model marsupial organism, and its value lies chiefly in the study of mammalian evolution, development and immunity. In a collection of articles published by BioMed Central, including a lead article in Genome Biology, the Australian-led, international Tammar Wallaby Genome Sequencing Consortium present the tammar wallaby genome and transcriptome sequences. These landmark datasets constitute the first kangaroo genome sequence and are enriched by a number of exciting biological findings that have only been made possible by the novel availability of sequencing data.
