Research interests

My research in the BASE team

2 pathways for crossover formation

2 pathways for crossover formation

Starting from linkage mapping for plant breeding applications, my research now mostly focuses on crossover number and distribution. In particular, I have been developing with mathematical models to simulate crossover interference. These models take into account the two different pathways of crossover formation which have been discovered in several organisms. Using these modeling approaches, we have unveiled the existence of these two distinct pathways of crossover formation in Maize, and investigated quantitative properties of crossover formation mechanisms in different species. In particular, we have demonstrated in Tomato that crossovers produced by two different pathways still can interfere with each other out to distances of about 6 microns.

Fluorescent markers FACS-based method for high-throughput measurement of recombination rate and crossover interference in the budding yeast

FACS recombination phenotyping (simple case of 2 markers)

More recently, with my PhD student Xavier Raffoux, we have developed experimental approaches using the budding yeast as a model species to investigate the genetics underlying quantitative variability of recombination rate and landscape along chromosomes.
First, we have developed a method to measure recombination rate and crossover interference at high-throughput by using fluorescent markers. We have developed 8 tester strains spanning entirely chromosomes VI and XI, and parly chromosome I. In each tester, 3 linked fluorescent markers have been inserted at about 30cM from each other, thus delimiting 2 consecutive intervals from which crossover interference can be measured with a very high accurracy (Ref)   .
Then we have applied this method to characterize the intra-specific diversity of recombination rate and interference in the species S. cerevisiae. In the different intervals analyzed, recombination showed up to 9-fold variation across strains but global recombination landscapes along chromosomes varied less. We also measured recombination rates in one region in 10 different crosses involving five parental strains. Our overall results indicate that recombination rate is increasingly positively correlated with sequence similarity between homologs. We also estimated that cis and trans effects explained respectively 38% and 17% of the variance of recombination rate (Ref)   .
Our main research interest now is about evolutionary aspects of meiotic recombination. Using our FACS-based method, we will implement experimental evolution under recurrent selection for modified increased or dereased rate, and use the evolved populations to investigate the role of recombination in adaptation to stress.

My research in the ACEP group

The ACEP group is an internal platform of services in the fields of genetic map construction and analyses of DNA polymorphism and gene expression. We provide DNA analysis service and keep a technological witch in molecular marker technologies. I also develop software tools for automated genetic mapping with large numbers of markers, and I have constructed high-density genetic maps in several plant species.

Current Projects

  1. Experimental evolution under recurrent selection for meiotic recombination rate
  2. Automatic construction of high-resolution linkage maps from data sets with high numbers of markers.
  3. Quantifying across successive generations how linkage slows down genetic progress and how to best use new technologies that enhance recombination rates.
