Genetic mapping methods provide a unique opportunity to study the interactions of
differentiated genes and genomes in a hybrid genetic background. After a brief discussion of …

Adaptive radiation is the evolution of diversity within a rapidly multiplying lineage. It can
cause a single ancestral species to differentiate into an impressively vast array of species …

The increasing number of invasive exotic plant species in many regions and the continuing
alteration of natural ecosystems by humans promote hybridization between previously …

Abstract Information concerning the area of origin, genetic diversity and possible acquisition
of germplasm through hybridization is fundamental to understanding the evolution, ecology …

Natural hybridization is a frequent phenomenon in plants. It can lead to the formation of new
species, facilitate introgression of plant traits, and affect the interactions between plants and …

Chez les plantes, les rétrotransposons sont largement inactifs lors du développement
normal mais peuvent être activés suite à des stress. Les rétrotransposons de type copia et …

Hybrid zones provide biologists with the opportunity to examine genetic and ecological
interactions between differentiated populations. Accurate identification of hybrid …

Abstract.—Experimental advanced‐generation backcross populations contain individuals
with genomic compositions similar to those resulting from interspecific hybridization in …

Although there are many studies of the evolution and ecology of hybrid zones, few extend
over long enough time periods to track evolutionary changes in the zones or assess the …

Parsimony analyses of morphology, restriction sites of the cpDNA, sequences from the
nuclear, ribosomal internal transcribed spacer (ITS), and the chloroplast gene rbcL were …
