Our research in plant and animal epigenetics has been driven by a strong interest in understanding and elucidating the molecular mechanisms of how plants and animals adapt to environmental signalling and how speciation barriers evolve in plants. We use a combination of next-generation sequencing, bioinformatics and synthetic biology to describe and elucidate the function of these components.

Epigenetics, broadly defined, refers to all genetic information not encoded in the DNA sequence, with the best-understood consequence of epigenetic modifications being the regulation of gene expression. Although gene transcription and protein synthesis is required for plant development, the full repertoire of epigenetic mechanisms underpinning biological adaptation and speciation barriers remain equivocal.

The majority of the genome is pervasively transcribed such that more than 90% of transcriptional activity is related to the production of various long non-coding RNAs (lncRNA), which possess no or limited protein-coding capacity. Expansion of these transcriptionally active non-coding sequences in plant and animal genomes appears to have occurred primarily in higher multicellular organisms. We have identified thousands of novel lncRNAs transcribed in plants.

Furthermore, we have demonstrated RNA modifications play an important role in extending the transcriptional space. Thus, both RNA modifications and lncRNAs represent attractive candidates for achieving context- and stimulus-specific epigenetic regulation of gene expression.

Fundamental Research-  We currently use a combination of molecular genetics, transcriptomics and bioinformatics (high-performance computing and synthetic biology) to answer our research questions on long non-coding RNAs and RNA modifications.

Honours, Masters, PhD and postdoctoral projects in genetics, epigenetics and bioinformatics are available.

Translational Research- We recently translated our wide-hybridisation technology to the Australian canola (Brassica napus) industry. In doing so we introduced disease resistance genes from either B. rapa or B. oleracea to synthesise B. napus (canola) with novel disease resistance. We are currently extending our translational canola research by connecting with international partners. Honours, Masters and PhD projects are available to develop the technology further in collaboration with industry partners. Are you a potential industry partner and want to connect? Don't hesitate to contact me.
