Understanding the nature, the number and the strength of barriers to gene flow is a major goal in speciation genomics. Yet, few speciation genes have been reported to date in plants. Considering the costs of NGS are still coming down, it becomes possible to identify such speciation genes at the pan-genomic level even for non-model species. This presentation will review our latest advances regarding this research topic within the European white oak complex.
We first established a reference genome for oak (1.5Gb/2C) organized into pseudo-chromosomes and used a deep pool sequencing approach to characterize 4 sympatric and interfertile species (Quercus petraea, Q. robur, Q. pyrenaica, Q. pubescens). Even if these species exhibit different ecological requirements (e.g. soil pH or moisture), they are still connected by substantial levels of 'interspecific' gene flow (FST
