Beskrivning av projektet
The genetics of incipient speciation was investigated in outcrossing Arabidopsis species. Postmating reproductive barriers were studied between A. lyrata, A. arenosa and A. halleri. The strongest barriers were observed in hybrid seed development and in hybrid pollen fertility. Whereas hybrid seed barrier was only observed between species (except when A. lyrata as a pollen recipient, A. halleri as a pollen donor), hybrid pollen fertility barrier was observed already in the between population hybrids within A. lyrata. Genetics of pollen fertility was studied, with help of high throughput sequencing and genetic mapping, in within species (between population) crosses and in between species crosses.
