Interspecific hybridization is a primary cause of extensive morphological and chromosomal
variation and plays an important role in plant species diversification. However, the role of …

The rhizoma peanut (Arachis glabrata Benth., section Rhizomatosae) is a tetraploid
perennial legume. Although several A. glabrata cultivars have been developed as forage …

Oplegnathus fasciatus and O. punctatus (Teleostei: Centrarchiformes: Oplegnathidae), are
commercially important rocky reef fishes, endemic to East Asia. Both species present an …

Abstract Backgrounds and Aims The genus Stylosanthes includes nitrogen-fixing and
drought-tolerant species of considerable economic importance for perennial pasture, green …

Background Rubus is a large and taxonomically complex genus exhibiting agamospermy,
polyploidy and frequent hybridization. The objective of this work was to elucidate rDNA …

Premise The origin of allopolyploids is believed to shape their evolutionary potential,
ecology, and geographical ranges. Morphologically distinct apomictic types sharing the …

Background Interspecific hybridisation resulting in polyploidy is one of the major driving
forces in plant evolution. Here, we present data from the molecular cytogenetic analysis of …

Polyploidy is the main mechanism for chromosome number variation in Cynodon.
Taxonomic boundaries are difficult to define and, although phylogenetic studies indicate that …

Interspecific hybridization and genome duplication to form allopolyploids are major
evolutionary events in angiosperms. In the parasitic genus Cuscuta (Convolvulaceae) …

Background The oat× maize addition (OMA) lines are used for mapping of the maize
genome, the studies of centromere-specific histone (CENH3), gene expression, meiotic …
