Isolation and characterization of intergeneric somatic hybrids in the Apocynaceae family
Protoplasts were isolated from callus cultures of Rauwolfia serpentina Benth., Rhazya stricta Decaisne, and Catharanthus roseus (L.) G. Don, or from leaves of Vinca minor L. Protoplast isolation, culture, and fusion techniques as well as hybrid screening systems were developed for these species, and hybrids were obtained. Hybrid combinations were Rauwolfia + Vinca, Rauwolfia + Catharanthus, Rauwolfia + Rhazya, and Catharanthus + Vinca. For hybrid isolation, the physiological complementation method was utilized. Analyses of the material obtained included a cytogenetic study of the chromosomes, a study of multiple molecular forms of transferases and esterases, and the blot hybridization of re…
Somatic Hybridization in the Family Apocynaceae (Catharanthus, Rauwolfia, Rhazya, and Vinca Species)
The Apocynaceae family includes about 2000 species belonging to approximately 200 genera (Takhtadjan 1981). The majority of species originate in the tropics, only a few of them are common to Europe (Vinca minor, V. herhaceae, V. major, genus Trachomitum).
