14 February 2024 News Release <\/p>\n
Researchers at CSIRO, Australias national science agency, have sequenced the first genome of the Night Parrot, one of the worlds rarest and most elusive birds. <\/p>\n
The development will answer questions about population genetics and biology that could boost conservation hopes for the recently rediscovered species. <\/p>\n
The genome will enable us to explore the genetic basis of why the Night Parrot is nocturnal, a very unusual feature in parrots. Well investigate faculties like navigation, smell, beak shape and its less-than-optimal night vision, Dr Leo Joseph, Director of CSIROs Australian National Wildlife Collection said. <\/p>\n
Researchers will also be able to run statistical analyses on the genome of this individual to estimate past population sizes of Night Parrot populations in Australia. <\/p>\n
Now, we have the capability to compare this annotated genome with other, closely related parrots, shedding light on the reasons behind its scarcity and limited distribution compared to many of its relatives. <\/p>\n
CSIRO researchers sequenced the Night Parrot genome its genetic blueprint using tissue obtained from Dr Kenny Travouillon, Acting Curator of Ornithology at the Western Australian Museum, after Traditional Owners in the Pilbara found the deceased specimen and delivered it to the Museum Boola Bardip. <\/p>\n
The specimen, which is the best-preserved on display in the world, is now open to public viewing at the WA Museum Boola Bardip. <\/p>\n
Dr Gunjan Pandey, who led the Night Parrot genomics project, said access to high-throughput DNA sequencing technology under CSIROs Applied Genomics Initiative is accelerating genomics research in Australia. <\/p>\n
We can now generate very high-quality genomes from really tiny tissue samples even as small as an ants head or a single mosquito, Dr Pandey said. <\/p>\n
This level of quality and detail just wasnt possible even five years ago. <\/p>\n
The genetic data can be used to ensure conservation programs maximise diversity, so the species is resilient and has the best chance of long-term survival. <\/p>\n
Once more widespread in arid Australia, the Night Parrot declined due to environmental changes such as predation by cats and foxes. <\/p>\n
It is now known only from localised parts of southwest Queensland and Western Australia. <\/p>\n
A couple of dozen scientific specimens were collected during the nineteenth century and one in 1912. Then a specimen was found in 1990 in southwest Queensland, Dr Joseph said. <\/p>\n
Live birds were reported from the same area in 2013, and a live parrot was finally caught and tagged in 2015. <\/p>\n
While the Night Parrot genome is an exciting scientific resource to understand more about this bird, protecting the species from cats, foxes, fire and habitat loss is also crucial for their conservation. <\/p>\n
The Night Parrot genome will open up numerous opportunities for further research to help conserve this species, Dr Pandey said. <\/p>\n
This will empower scientists to develop a plan for saving the Night Parrot, which is the ultimate goal of sequencing the genome and making it publicly available. <\/p>\n
Note to editors <\/p>\n
The National Center for Biotechnology Information (NCBI) at the National Library of Medicine (NLM) annotated the genome sequence of the Night Parrot (Pezoporus occidentalis). The locations of individual genes were found using NCBIs Eukaryotic Annotation Pipeline (EGAP). The annotated genome is now available online as part of the NCBI Reference Sequence (RefSeq) Database through NCBI Datasets. <\/p>\n
CSIRO together with the Threatened Species Initiative, supported by Bioplatforms Australia, will continue genetic studies to understand more about the Night Parrot and other closely related birds such as the Eastern Ground Parrot. <\/p>\n
CSIROs Applied Genomics Initiative (AGI) uses high throughput sequencing technology to deliver reference genomes and large-scale diversity datasets for new insights and applied outcomes. <\/p>\n
The genome was sequenced using Oxford Nanopore technology at the Biomolecular Resource Facility (BRF) at the Australian National University (ANU). BRF is a service node of Bioplatforms Australia which is made possible through investment funding provided by the Commonwealth Government National Collaborative Research Infrastructure Strategy (NCRIS). The AGI has successfully assembled over 100 genomes across diverse life forms in recent years, and many of these annotated genomes are accessible to the publicvia GenBank . <\/p>\n
