Role of a histone demethylase during seed development
This project in epigenetics and plant reproductive biology will examine the role of a histone demethylase (H3K9me2) during seed development.
Our recent data demonstrated that it is essential for development as seeds abort before maturity. The project will involve using chromatin IP and RNA-seq to characterise the histones that and genes in the mutant seeds.
Study epigenetics and plant reproductive biology
Our overarching aim is to use the model plant Arabidopsis thaliana to understand the molecular basis of complex traits and translate these discoveries into crop plants like canola and cereals such as barley, wheat and rice.
We have discovered that Arabidopsis has a complex repertoire of non-coding RNAs that vastly exceeds the number of protein coding genes thereby supporting the RNA world hypothesis.
Research projects in our laboratory aim to elucidate the function of these non-coding RNAs during seed and plant development.
Our recent publications have demonstrated that many non-coding and coding RNAs have a hidden layer of chemical modifications thereby increasing the functional complexity of RNA.
