Meiotic recombination in plants

Christophe Lambing, Genetic and Epigenetic Inheritance in Plants Group, Department of Plant Sciences, University of Cambridge

The interest of studying "meiosis" has increased significantly over the past 5-10 years before it become apparent that it is not possible to extensively increase the yield of the widely used cultivars due to their limited genetic diversity (mostly because of the domestication process).

Therefore it is important to cross the current cultivar with a close relative species through sexual reproduction and allow both genome to recombine and reshuffle. However some genomic regions (principally the regions close to the centromeres) are epigenetically silence and thus their chromatin are more compact and less accessible to proteins. This results in low recombination rate on these regions. Unfortunately several loci with agricultural values are located close to the centromere and therefore it is difficult for the breeders to recombine these loci and introduce more genetic diversity. one focus in the lab is to understand what factors are involved in the silencing of regions close to the centromeres and whether it is possible to remodel the epigenetic landscape in a way that will allow recombination to happen on these silence regions. Among these factors silencing the genomes are DNA methylation, methylation of histone 3 at the residue lysine  9 and chromatin remodellers
