Koalas have been observed to sniff leaves before tasting them 41, and their acute discrimination has been correlated with the complexity and concentration of plant secondary metabolites 42. While koalas are a national symbol of Australia’s unique wildlife, they can only be found in the wild on the southeast and eastern sides of Australia, along the coastlines of Queensland, New South Wales, South Australia and Victoria.

At a continental scale, we show biogeographic barriers to gene flow associated with the Brisbane Valley and Clarence River, as identified by mtDNA studies 68, 72, and find a barrier associated with the Hunter Valley, which was not previously known in koalas (Fig. As in other mammalian genomes, short interspersed nuclear elements (SINEs) and long interspersed nuclear elements (LINEs) are the most numerous elements (35. Preliminary case/control association tests for five koalas involved in a chlamydia vaccination trial showed that the MHCII DMA and DMB genes, as well as the CD8-a gene, may be involved in differential immune responses to chlamydia vaccine (Supplementary Table 21 and Supplementary Note). We reveal that the koala’s ability to detoxify eucalypt foliage may be due to expansions within a cytochrome P450 gene family, and its ability to smell, taste and moderate ingestion of plant secondary metabolites may be due to expansions in the vomeronasal and taste receptors.We analyzed populations of recent koala samples using 1,200 SNPs derived from targeted capture libraries mapped to the koala genome ( Supplementary Note).

We sequenced the koala genome, producing a complete and contiguous marsupial reference genome, including centromeres. This is consistent with fossil evidence of rapid declines in multiple Australian species, including the extinct megafauna, 40,000–50,000 years ago 66 and 30,000–40,000 years ago 67.Consequences of the interaction between nutrients and plant secondary metabolites on herbivore selectivity: benefits or detriments for plants?

Germline mutation rates and the long-term phenotypic effects of mutation accumulation in wild-type laboratory mice and mutator mice.About 30 × of 150 bp paired-end Illumina X Ten short reads from Bilbo was used as an input for this polishing process, which was run on a compute cluster provided by Intersect Australia Limited.

It is likely that most of these 73 loci are endogenous, consistent with our observation of integration breakpoint sequences that are shared with one or both of the other koala genomes reported (Supplementary Tables 23 and 24).
