Abstract excerpt
In angiosperms, interspecific crosses often display hybrid incompatibilities that are manifested as under-proliferation or over-proliferation of endosperm. Recent analyses using crosses between Arabidopsis thaliana and its related species with different ploidy levels have shown that interspecific hybridization causes delayed developmental transition and increased mitotic activity in the endosperm. In this study,...
