[Restriction variability of amplified chloroplast DNA fragments in genus Nicotiana].
Restriction analysis of amplificated chloroplast DNA fragments has allowed us to determine the source of cytoplasm for several natural diploids and amphidiploids of the genus Nicotiana. N. corymbosa or species of Trygonophyllae section donated cytoplasm to N. bigelovii and N. clevelandii, while N. arentsii inherited cytoplasm from N. undulata during the evolution of the genus. Plastomes of Repandae and Nudicaules species orginated from now extinct species of Trygonophyllae section.
