Evolution (Genissel's group)

Research Topics

A Genissel's group. We are a small group and we study evolution and adaptation of the fungal pathogen Zymoseptoria tritici. Our main research questions revolve around the understanding of host adaptation and adaptation to abiotic changes as well.

What molecular variants are involved in quantitative variation of virulence in the fungal populations? What are the consequences of rapid adaptation at the genome level? What is the role of phenotypic plasticity in fungal evolution under fluctuating selection?

We combine several approaches to address these questions: population genomics, evolutionary quantitative genetics, experimental evolution and bioinformatics. 

Training Opportunity (second year Master)

Mobile DNA are ubiquitous components of eukaryotic genomes. Besides the deleterious effect caused by TE activity, TEs may also play a part in phenotypic evolution and adaptation, for instance by modifying gene expression level due to mutation in cis-regulatory regions. We are recruiting a Master student to study the evolution of transposable elements  (TE) during experimental evolution under a fluctuating regime, in clonal populations of the fungus Zymoseptoria tritici. Genomic and transcriptomic data will be used to decipher the dynamic of TE evolution (insertion polymorphism, level of expression of TE). The Master student will be based in the team of Aurelie Hua-Van and Arnaud Le Rouzic at EGCE, Paris Saclay University, and will work closely with Anne Genissel (Bioger, Paris Saclay University). Please feel free to contact me for more information.
