Karyotype Analysis of Four Vicia Species using In Situ Hybridization with Repetitive Sequences

Karyotype analysis in Vicia

The genus Vicia includes species that differ up to 7.5-fold in their nuclear DNA content. This makes Vicia a good model to study plant genome and karyotype evolution. Navr�tilov� et al. (pp. 921-926) examine karyotypes of four Vicia species with respect to localization of five families of tandem repeats. The results show considerable divergence even between closely related species.
