Overview

The main objective of our group is to increase our knowledge on the structure of plant genomes and study how these genomes evolve. Our group has actively participated in the sequencing and annotation of the Arabidopsis, Physcomitrella patens, melon and almond genomes and is working on 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 are studying the regulation of transposon activity as well as their impact on the generation of the genetic and epigenetic variability useful for plant adaptation and crop breeding.
