Evidence for multiple interspecific hybridization in Saccharomyces sensu stricto species.

Fluorescent amplified fragment length polymorphism analysis demonstrates a high level of gene exchange between Saccharomyces sensu stricto species, with some strains having undergone multiple interspecific hybridization events with subsequent changes in genome complexity. Two lager strains were shown to be hybrids between Saccharomyces cerevisiae and the alloploid species Saccharomyces pastoria...

Interspecific Hybridization in Pinus: a Summary Review

The pines and other groups of temperate forest trees often fail to conform to widely accepted principles of plant evolution that are based primarily on observations of herbaceous plants. For example, interpreters of plant evolution tend to equate the fertility or sterility of inter specific hybrids with the magnitude of the genetically controlled reproductive barriers limiting the production of...

Natural Interspecific Hybridization in Gunnera (Gunneraceae)

Natural interspecific hybridization between Gunnera bracteata and G. peltata (Gunneraceae) in the Juan Fernandez Islands, Chile, is analyzed morphologically and chemically. Parental types from isolated populations were compared with parents and intermediates occurring together in Quebrada Villagra on Masatierra. Two transects were made in that area, one in a relatively undisturbed site, and ano...

Hybridization and invasion: one of North America's most devastating invasive plants shows evidence for a history of interspecific hybridization

Hybridization has been hypothesized to influence invasion through the generation of novel phenotypes and/or increased levels of genetic variance. Based on morphology, hybrids between diffuse knapweed and spotted knapweed, two invasive plants in North America, are present in the invaded range. Some individuals within most diffuse knapweed sites in North America exhibit intermediate diffuse × spo...
