The western ringtail possum refers to a marsupial, a species of possum, Pseudocheirus occidentalis, found in a small area of Southwest Australia (including Perth where DNA Zoo Australia headquarters is located). Western ringtail possums are critically endangered  and could be wiped out in 20 years unless something is done to save the species .
In order to help with the species conservation, we, in collaboration with the Mallarino Lab at Princeton University, share a de novo genome assembly for the western ringtail possum, here. The sample for generating the necessary sequencing libraries (short insert-size DNA-Seq and Hi-C) was donated by the Australian Biological Tissue Collection at the South Australian Museum. Included in the share are the homology-based annotations for the species, courtesy MacManes Lab.
The western ringtail possum is a member of the Diprotodontia (meaning “two front teeth”) order, in the Phalangeriformes suborder (possums, gliders and cuscus). The other two suborders of Diprotodontia are: Vombatiformes (wombats and koalas) and Macropodiformes (kangaroos and wallabies).
DNA Zoo has generated chromosome-length genome assemblies in all three of the listed suborders: ground cuscus in Phalangeriformes, common wombat in Vombatiformes and tammar wallaby, western grey kangaroo, eastern grey kangaroo and red kangaroo in the Macropodiformes. See some whole-genome alignment plots below for an idea on how the chromosomes of different Diprotodontia species spanning the last 28MY of evolution relate to each other: a rather plastic karyotype despite the deceivingly similar chromosome count!
