Evolutionarily diverged regulation of X-chromosomal genes as a primal event in mouse reproductive isolation. [PDF]

PLoS Genetics, 2014
Improper gene regulation is implicated in reproductive isolation, but its genetic and molecular bases are unknown. We previously reported that a mouse inter-subspecific X chromosome substitution strain shows reproductive isolation characterized by male ...

Genetic Variability of the Mating Recognition Gene in Populations of Brachionus plicatilis

Diversity, 2022
The development of reproductive barriers promotes within-species divergence and is a requisite for speciation to occur. Mate recognition in the rotifer B. plicatilis is mediated through a surface glycoprotein called Mating Recognition Protein (MRP). Here

A Novel Combination of Genes Causing Temperature-Sensitive Hybrid Weakness in Rice

Frontiers in Plant Science, 2022
Reproductive isolation is an obstacle for plant breeding when a distant cross is demanded. It can be divided into two main types based on different growth stages: prezygotic isolation and postzygotic isolation.

Asymmetric reproductive isolation between two sympatric annual killifish with extremely short lifespans. [PDF]

PLoS ONE, 2011
BACKGROUND: Interspecific reproductive isolation is typically achieved by a combination of intrinsic and extrinsic barriers. Behavioural isolating barriers between sympatric, closely related species are often of primary importance and frequently aided by

The contribution of multiple barriers to reproduction between edaphically divergent lineages in the Amazonian tree Protium subserratum (Burseraceae)

Ecology and Evolution, 2020
Disentangling the strength and importance of barriers to reproduction that arise between diverging lineages is central to our understanding of species origin and maintenance. To date, the vast majority of studies investigating the importance of different

Prepollination barriers prevent gene flow between co-occurring bat-pollinated bromeliads in a montane forest [PDF]

PeerJ
Background Reproductive isolation mechanisms in flowering plants are fundamental to preserving species’ evolutionary independence and to enabling the local coexistence of closely related species.

The past, present, and future of ecogeographic isolation between closely related Aquilegia plants

Ecology and Evolution, 2023
Quantifying the strength of the ecogeographic barrier is an important aspect of plant speciation research, and serves as a practical step to understanding the evolutionary trajectory of plants under climate change.

Conspecific olfactory preferences and interspecific divergence in odor cues in a chickadee hybrid zone

Ecology and Evolution, 2019
Understanding how mating cues promote reproductive isolation upon secondary contact is important in describing the speciation process in animals. Divergent chemical cues have been shown to act in reproductive isolation across many animal taxa.

First evidence for postzygotic reproductive isolation between two populations of Eurasian perch (Perca fluviatilis L.) within Lake Constance

Frontiers in Zoology, 2008
Background The evolution of reproductive traits, such as hybrid incompatibility (postzygotic isolation) and species recognition (prezygotic isolation), have shown their key role in speciation.

Prospects of utilization of inter-subspecific heterosis between indica and japonica rice

Journal of Integrative Agriculture, 2020
The Asian cultivated rice (Oryza sativa L.) grown worldwide is divided into two subspecies, indica and japonica. It is well known that the heterosis of inter-subspecies is usually stronger than that of intra-subspecies.
