The paper shows that selfing Draba species lack endosperm-based hybrid barriers and exhibit maternal bias in genomic imprinting, suggesting reduced parental conflict and adaptive maternal expression.

The paper identifies a genetic locus and environmental factors that influence endosperm cellularization in Arabidopsis hybrids, affecting seed viability and hybridization barriers.

This study identifies spatial and temporal regulation of parent-of-origin allelic expression in endosperm domains using FANS and RNASeq.
