Biography

Professor of Epitranscriptomics

Rupert's main research interest is the study of messenger RNA (mRNA) methylation in plants and other eukaryotes. His group studies the enzymes involved in the synthesis of N6 methyladenosine, the mRNAs that are targeted for methylation, the consequences of this methylation and the proteins that recognise the modified nucleotide.

He also has a long standing interest in synthetic biology approaches to crop improvement with research areas including the manipulation of plant-microbe interactions through "quorum sensing", chloroplast transformation systems and the production of taxanes in heterologous plant systems.

Expertise Summary

Detection and quantification of modified nucleotides in mRNA.

Manipulation of metabolic pathways for the production of novel products in transgenic plants.

Teaching Summary

Rupert convenes unergraduate and post graduate modules in" Molecular Pharming" and Plant "Cell Signalling" .

In addition he contributes lectures to "Plant Science", "Plant Biotechnology", "Resource Capture", "Sex Flowers and Biotechnology", "Genetics".

Current Research

My Group studies the role of post-transcriptional adenosine methylation in mRNA. N6-methyladenosine (m6A) is a ubiquitous modification present in the messenger RNA of many eukaryotes and nuclear-replicating viruses. Unlike cap methylation, it can be found throughout the message and has been detected in coding, non-coding and intron sequences. However, despite its widespread occurrence, its function has remained a mystery since its discovery over 30 years ago. This modification is common in most eukaryotes and in plants it appears to be essential. Adenosines in the sequence context GAC or AAC can become methylated, but the average frequency of methylated adenosine is only once per 500 nucleotides. However, not all mRNAs contain the modification, indicating that additional features must be required for specificity. We have recently shown that m6A levels in Arabidopsis mRNA vary between different plant tissues. In addition, MTA, the Arabidopsis homologue of the human mRNA methylase, is required for embryo development and interacts in vitro and in vivo with AtFIP37, a plant homologue of the Drosophila protein female lethal 2 D and of human WILMS' TUMOUR 1-ASSOCIATING PROTEIN.

Previously I held a BBSRC Sir David Philips Research Fellowship which supported my research concerning the role of "quorum sensing" during interactions between plants and various gram negative bacteria. Some work in this area continues within the Group.
