Geographic Range Dynamics Drove Ancient Hybridization in a Lineage of Angiosperms [PDF]
Abstract Factors explaining global distribution patterns have been central to biology since the 19th century, yet failure to combine dispersal-based biogeography with shifts in habitat suitability remains a present-day setback in understanding geographic distributions present and past, and time-extended trajectories ...

The emergence of new fungal pathogens through hybridization represents a serious challenge for agriculture. Hybridization between the wheat mildew (Blumeria graminis f. sp. tritici) and rye mildew (B. graminis f. sp.

Karyotypes of Danubian lineage brown trout and their hybrids
Cytogenetic analysis of brown trout, Salmo trutta, have been described for different populations and morphs; however, cytogenetic analysis of interspecific brown trout hybrids is unknown. Cultured kidney cells from four brown trout subspecies (Salmo trutta abanticus, S.t. caspius, S.t. fario and S.t. labrax) and their reciprocal hybrids were karyotyped

Population Genetics of a Polyploid: Is There Hybridization Between Lineages of Hyla versicolor? [PDF]
Several studies have demonstrated that polyploid species can form recurrently from their progenitors, but few studies have evaluated gene flow between the resultant polyploid lineages. Here we examine the possibility of hybridization between lineages of the tetraploid common gray treefrog (Hyla versicolor).

Isolation and identification of a novel rabies virus lineage in China with natural recombinant nucleoprotein gene. [PDF]
Rabies virus (RABV) causes severe neurological disease and death. As an important mechanism for generating genetic diversity in viruses, homologous recombination can lead to the emergence of novel virus strains with increased virulence and changed host ...

Interspecific hybrid lethality and sterility are a consequence of divergent evolution between species and serve to maintain the discrete identities of species.

Hybridization and the origin of new yeast lineages
ABSTRACTHybrids originate from the mating of two diverged organisms, resulting in novel lineages that have chimeric genomes. Hybrids may exhibit unique phenotypic traits that are not necessarily intermediate between those present in the progenitors. These unique traits may enable them to thrive in new environments.

Cis-by-Trans regulatory divergence causes the asymmetric lethal effects of an ancestral hybrid incompatibility gene. [PDF]
The Dobzhansky and Muller (D-M) model explains the evolution of hybrid incompatibility (HI) through the interaction between lineage-specific derived alleles at two or more loci. In agreement with the expectation that HI results from functional divergence,

Cryptic and extensive hybridization between ancient lineages of American crows [PDF]
Abstract Most species and therefore most hybrid zones have historically been defined using phenotypic characters. However, both speciation and hybridization can occur with negligible morphological differentiation.
