Associations of Plant Tumors with chemical compounds

  • The observed variation in the organization of T-DNA in octopine crown gall tissue did not appear to be a characteristic of the way the tissue was derived [19].
  • Genetic analysis of T-DNA transcripts in nopaline crown galls [5].
  • Transient expression of a T-DNA-encoded beta-glucuronidase gusA gene is efficient, but the ecotype is deficient in crown gall tumorigenesis, transformation to kanamycin resistance, and stable GUS expression [24].
  • The presence of pyronopaline in crown gall tumor tissue and the catabolism of it by the bacterium A. tumefaciens establish it as a new opine [25].
  • The Mr 18.000 protein represented a fusion product between chloramphenicol acetyltransferase (CAT) on pACYC184 and a part of lysopine dehydrogenase (LpDH), the enzyme synthesizing octopine and lysopine in plant tumor cells [26].
