Article Synopsis
  • - Hybrid seed inviability (HSI) plays a crucial role in reproductive isolation, impacting speciation by varying in strength among diploid species and potentially influencing ploidy-variable species as well.
  • - The study examined HSI variation within a diploid-autotetraploid species using data from 12 population pairs across three different contact zones, focusing on the effects of crossing direction, ploidy differences, and spatial arrangement on reproductive barriers.
  • - Results revealed significant parent-of-origin effects on endosperm development and hybrid performance, indicating that these variations contribute to interploidy reproductive isolation and the overall fitness of the species, highlighting HSI as a key factor regardless of evolutionary history.
