Role of endogenous selection and edaphic adaptation in shaping the fitness of tetraploid Arabidopsis hybrids in Wachau suture zone
Arabidopsis lyrata tetraploid hybrids in the Wachau suture zone have undergone genome duplication and colonized from calcareous habitat to a new siliceous habitat (potentially via adaptive introgression). The adjoining Arabidopsis arenosa populations are most likely the original source of siliceous alleles, which may have allowed A. lyrata escape their narrow ecological niche (calcareous bedrock) to colonize the siliceous bedrock. In these suture zones, the hybrids exhibit A. lyrata maternal background suggesting the presence of isolation asymmetryin fertility (or survivorship) of reciprocal hybrid crosses. It provides an opportunity to investigate the relative contributions of endogenous and exogenous selection in shaping the fitness of the hybrids in this suture zone.
