Abstract: Interest in understanding hybrid seed failure (HSF) has mushroomed, both in terms of identifying underlying molecular processes and their evolutionary drivers. We review phenotypic and molecular advances with a focus on the 'effective ploidy' concept,… read more here.

Abstract: Hybrid seed lethality is a widespread type of reproductive barrier among angiosperm taxa1,2 that contributes to species divergence by preventing gene flow between natural populations3,4. Besides its ecological importance, it is an important obstacle to… read more here.
