Hybridization of diverged taxa often result in lethality or sterility. We previously described natural variation for postzygotic incompatibility in the cross of diploid Arabidopsis thaliana to Arabidopsis arenosa. Hybrid seed death in this system has a complex genetic basis, involving many non-addit...
ORGANISM(S): Arabidopsis thaliana 
Seed development is dependent on a well-orchestrated interplay between different transcriptional programs operating in the embryo, the endosperm and the maternally derived seed coat. In angiosperms, the embryo and the endosperm are products of double fertilization during which the two pollen sperm c...
