Physiological comparisons of transformed (crown gall) and nontransformed Vinca rosea L. cells.

Abstract

In vitro growth rates of transformed (crown gall) and nontransformed cultures ofVinca rosea L. were greater at 32°C than at 25°C. The growth of transformed cells was significantly inhibited by kanamycin, neomycin, and chloramphenicol but not by cycloheximide. Nontransformed cells were inhibited by all four antibiotics., The relative growth rates of transformed cultures induced by four different strains, ofAgrobacterium tumefaciens did not correspond to the relative rates of tumor weight increase observed in vivo nor with the relative weights of tumor tissue in, plants 8 weeks after inoculation with the corresponding bacterial strains.
