Conference with Jeffrey Bennetzen on 26 June - 26/06/2008
Jeffrey Bennetzen, professor at the University of Georgia (USA) will hold a conference on “Hyper and Very Hyper Evolution of Flowering Plant Genomes” on 26 June at 10 AM in the J. Alliot Amphitheater on the CIRAD Campus in Montellier. Bennetzen is currently spending a sabbatical year in the DAP research unit of the Foundation’s scientific network, with support from the Foundation.
Subject: Plant genomes are unusual in both their complexity and their variability. Genome sizes, repeat content and gene arrangement change dramatically within just a few million years, primarily through an accumulation of very many events at very small physical scales. Our lab has determined the nature and rates of most of these genome-altering phenomena, and have observed that all of this change could occur in the absence of selection, merely as an outcome of species-specific properties of transposon regulation, recombination and DNA repair. A few regions in plant genomes show exceptional rates of genomic change even against this generally turbulent background, suggestive of diversifying selection that acts on genome structure per se.
