Structure and evolution of plant genomes

The main objective of our group is to increase our knowledge on the structure of plant genomes and study how these genomes evolve. After the sequencing of model plants such as Arabidopsis thaliana, with the development of NGS techniques is now possible to sequence and characterize the genomes of crop species. Our group has actively participated in the sequencing and annotation of the Arabidopsis thaliana and melon genomes and will concentrate in the next future in the study of crop genome evolution using resequencing data from crop varieties. This work should allow us to better understand how genome variability is generated and how this variability correlates with phenotypic variability in traits that have been selected by humans during crop domestication and breeding.

One of the major drivers of variability in plants are transposable elements. For this reason we have pay a special attention to these elements in the past, and we will continue to study them in the future.
