UNSW students have sequenced the chloroplast genome of the ancient Wollemi Pine a world first that could reveal how a "dinosaur" of the tree kingdom survived 200 million years of shifting continents and changing climates.
Using next-generation sequencing machines in the Ramaciotti Centre for Gene Function Analysis, the students have produced a draft sequence of the approximately 180,000 nucleotides of the DNA code of the Wollemi's chloroplast genome.
The Wollemi (Wollemia nobilis
) was known to science from fossil records but was thought to be extinct until 1994 when David Noble discovered it in a remote rainforest canyon in Wollemi National Park, 150 kilometres north-west of Sydney.
The research project exposed students to leading-edge technology that allowed them to obtain sequence data equivalent to the size of the human genome in just a few months. Exposure to this technology is rare in degree-level science programs, and was made possible by the outstanding sequencing research facilities at UNSW and an ongoing collaboration between researchers and the Royal Botanic Gardens Sydney.
