Transfer of the Agrobacterium tumefaciens TI Plasmid to Avirulent Agrobacteria and to Rhizobium ex planta
Abstract
Summary: A mutant of A. tumefaciens strain B6S3, carrying the R factor RP4, was able to transfer its TI plasmid to various avirulent Agrobacterium strains and to a strain of Rhizobium. Strains carrying the TI(B6S3) plasmid were selected by their ability to utilize octopine. The isolates were able to induce tumours and exclude phage AP1. The tumours induced on Kalanchoë daigremontiana were rough and contained octopine. It was concluded that octopine utilization, phage exclusion, induction of rough tumours and synthesis of octopine in the tumours are determined by the TI(B6S3) plasmid. Tumorigenicity was determined this plasmid both in Agro-bacteria and in Rhizobium, suggesting that all the genes necessary for tumour induction are plasmid-borne.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
