Understanding the Barriers to Interspecific Hybridization in Neurospora

Understanding the Barriers to Interspecific Hybridization in Neurospora. (May 2012) Sameer Rajendra Gajjar Department of Biochemistry and Biophysics Texas A&M University Research Advisor: Dr. Rodolfo Aramayo Department of Biology Crosses between two species of Neurospora are typically sterile and result in the production of non-viable or few viable ascospores. It is unclear what prevents succes...

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...

Interspecific hybridization increases transposition rates of Osvaldo.

Several authors have postulated that genetic divergence between populations could result in genomic incompatibilities that would cause an increase in transposition in their hybrids, producing secondary effects such as sterility and therefore starting a speciation process. It has been demonstrated that transposition largely depends on intraspecific hybridization for P, hobo, and I elements in Dr...
