Hybridisation within the wheat (Triticum aestivum)-Elytrigia intermedia-E. repens species complex a probable case of crop - wild relative gene flow (GA206/05/0778)

in agro- and natural ecosystems. Because we know that gene flow can occur but we don't know how the genes can influence natural ecosystems, it is necessary to evaluate the possibility of gene flow before ...

Why are species separated? Barriers to gene flow between species of the Triturus cristatus superspecies (GA206/01/0695)

What are the mechanisms causing reproductive isolation? There is a long-term debate on contribution of evolutionary factors preventing gene flow between diverging populations. Here, we present an unique model of speciation involving...

Spontaneous hybridisation of cultivated and wild taxa, gene introgression as agricultural value or threat? (7AMB13AR002)

The gene introgression from cultivated to crop wild relative species and vice versa is a subject of disputes for their usabilitly in genetics and breeding and/or for their threat of uncontrolled gene flow to the nature. The...

Evolutionary dynamics of the polyploid Aster amellus at the contact zone (GPP506/10/P188)

The project aims to understand the processes determining the evolution of polyploid through the study of the mechanisms responsible for the establishment and maintenance of various cytotypes and their coexistence in the contact zone through the study...

Genomic dissection of barriers to gene flow in hybridising fire-bellied toads (GA16-26714S)

The process of speciation involves the accumulation of genetic factors that reduce gene flow between differentiated populations and can be envisaged at the genomic level as the gradual spread of chromosomal regions that are barred f...

Genome duplication as an imperfect barrier in speciation? Evolutionary drivers and consequences of inter-ploidy introgression in natural populations (GA20-22783S)
