RESEARCH SUMMARY

The work of our group focuses on two main research themes. On the one hand, we are interested in genes that participate in the N6 methylation of adenosine residues in the mRNA, using the plant Arabidopsis thaliana as a model organism. On the other, we are interested in developing applications for the analysis of next-generation sequencing data, at the interface between genetics and bioinformatics. 

RESEARCH LINES

 

Line 1: Genetic analysis of the mechanism of N6-methylation of adenosine residues

The reversible N6-methylation of adenosine residues is one of the many post-transcriptional modifications known to occur on messenger RNA (mRNA) molecules. N6-methyladenosine (m6A) has been detected in all studied eukaryotes. Despite this modification has been known for about 4 decades, we have seen a renewed interest on its study over the last few years. Some recent advances in this field are the identification of the multisubunit methyltransferase (“writer”) complex responsible for the methylation of adenosine residues, the identification of enzymes with m6A demethylase (“eraser”) activity, and the identification of the YTH domain, which is present in proteins that bind to mRNAs containing m6A (“readers”). Despite these advances, the functions of m6A at the cellular level and during plant development are still poorly understood. One of our goals is to identify targets and protein-protein interactions that are important for the post-transcriptional regulation of gene expression by m6A. 

Line 2: Application of bioinformatic tools to plant genetics

Massively parallel sequencing technologies are enabling the sequencing of numerous genomes and transcriptomes at an affordable price. One of our goals in this area focuses on the development of improved methods for the assembly of plant transcriptomes, particularly those of some cultivated plants. We are using the identified sequences to develop molecular markers and other tools for the study of some agriculturally important crop species.
