In the past decade, advances in genome sequencing have allowed researchers to uncover
the history of hybridization in diverse groups of species, including our own. Although the …

Intrinsic postzygotic isolation typically appears as reduced viability or fertility of interspecific
hybrids caused by genetic incompatibilities between diverged parental genomes …

Although intrinsic postzygotic reproductive barriers can play a fundamental role in
speciation, their underlying evolutionary causes are widely debated. One hypothesis is that …

The evolution of predominant self‐fertilisation frequently coincides with the evolution of a
collection of phenotypes that comprise the 'selfing syndrome', in both plants and animals …

In plants, de novo DNA methylation is guided by 24-nt short interfering (si) RNAs in a
process called RNA-directed DNA methylation (RdDM). Primarily targeted at transposons …

Hybrid seed failure arising from wide crosses between plant species is a recurring obstacle
in plant breeding, impeding the transfer of desirable traits. This postzygotic reproductive …

MADS-box transcription factors (TFs) are ubiquitous in eukaryotic organisms and play major
roles during plant development. Nevertheless, their function in seed development remains …

Genomic conflicts may play a central role in the evolution of reproductive barriers. Theory
predicts that early-onset hybrid inviability may stem from conflict between parents for …

The endosperm, a transient seed tissue, plays a pivotal role in supporting embryo growth
and germination. This unique feature sets flowering plants apart from gymnosperms …

The endosperm is a developmental innovation of angiosperms that supports embryo growth
and germination. Aside from this essential reproductive function, the endosperm fuels …
