DOI: 10.1002/yea.3282
Abstract: Errors in meiosis can be important postzygotic barriers between different species. In Saccharomyces hybrids, chromosomal missegregation during meiosis I produces gametes with missing or extra chromosomes. Gametes with missing chromosomes are inviable, but we do… read more here.

DOI: 10.1093/biolinnean/blz135
Abstract: Animal gametes unite to form a zygote that develops into an adult with gonads that, in turn, produce gametes. Interruption of this germinal cycle by prezygotic or postzygotic reproductive barriers can result in two cycles,… read more here.

Rampant Misexpression in a Mimulus (Monkeyflower) Introgression Line Caused by Hybrid Sterility, Not Regulatory Divergence

DOI: 10.1093/molbev/msaa071
Abstract: Abstract Divergence in gene expression regulation is common between closely related species and may give rise to incompatibilities in their hybrid progeny. In this study, we investigated the relationship between regulatory evolution within species and… read more here.

Meiotic Recognition of Evolutionarily Diverged Homologs: Chromosomal Hybrid Sterility Revisited

DOI: 10.1093/molbev/msad083
Abstract: Abstract Hybrid sterility (HS) is an early postzygotic reproductive isolation mechanism observed in all sexually reproducing species. Infertility of hybrids prevents gene flow between incipient species and leads to speciation. While Drosophila studies have focused… read more here.

DOI: 10.3389/fpls.2022.908342
Abstract: Intraspecific hybrid sterility is a common form of postzygotic reproductive isolation in Asian cultivated rice, which is also the major obstacle to utilize the strong heterosis in the rice breeding program. Here, we review recent… read more here.

Introgression of a Complex Genomic Structural Variation Causes Hybrid Male Sterility in GJ Rice (Oryza sativa L.) Subspecies

DOI: 10.3390/ijms232112804
Abstract: Hybrids between different subspecies of rice Oryza sativa L. commonly show hybrid sterility. Here we show that a widely planted commercial japonica/GJ variety, DHX2, exhibited hybrid sterility when crossing with other GJ varieties. Using the… read more here.
