Hybrid lethality is a type of reproductive isolation barrier observed in two developmental
stages, hybrid embryos (hybrid seeds) and hybrid seedlings. Hybrid lethality has been …

Reproductive isolation poses a major obstacle to wide hybridization and introgression
breeding of plants. Hybrid inviability in the postzygotic isolation barrier inevitably reduces …

Dwindling fossil fuel reserves and poor environmental credentials of chemical synthesis
means, new renewable sources for the production and manufacture of valuable chemicals …

Hybrid lethality, meaning the death of F1 hybrid seedlings, has been observed in many plant
species, including Nicotiana. Previously, we have revealed that hybrids of the selected …

Key message Identification and inactivation of hybrid lethality genes can be used to expand
the available gene pool for improvement of a cultivated crop species. Abstract Hybrid …

Hybrid lethality, a type of postzygotic reproductive isolation, is an obstacle to wide
hybridization breeding. Here, we report the hybrid lethality that was observed in crosses …

Wild tobacco species in the Nicotiana section Suaveolentes are promising genetic
resources to introduce their disease resistance to cultivated tobacco, Nicotiana tabacum …

Background Many species of Nicotiana section Suaveolentes produce inviable F1 hybrids
after crossing with Nicotiana tabacum (genome constitution SSTT), a phenomenon that is …

Background A linkage map consisting of 24 linkage groups has been constructed using
simple sequence repeat (SSR) markers in Nicotiana tabacum. However, chromosomal …

Reproductive isolation is a mechanism that separates species. It is considered to play a
crucial role in the evolution of animals and plants. Reproductive isolation is divided into two …
