The Role of Certain Vitamins and Metallic Elements in the Nutrition of the Crown-Gall Organism.
The growth factors and minor metallic elements required for the best development of the crown-gall organism, Phytomona8 tumefaciens (Smith and Town.) Bergey et al., have been examined in contimuing studies on its nutrition. The importance of sources of nitrogen and carbon and certain physical chemical factors has been shown by several investigators (e.g., Sagen et al., 1934, Pinckard, 1935). Th...
متن کاملThe bases of crown gall tumorigenesis.
The nine decades since Smith and Townsend demonstrated that Agrobacterium tumefaciens causes plant tumors (95) have been marked by a series of surprises. Among the most important of these was the report in 1958 that these tumors could be excised and propagated in vitro without exogenous plant hormones (7). Equally important were a series of reports beginning about the same time that tumors rele...
متن کاملBiological Control of the Crown Gall Disease
A combination of the crown gall biocontrol strain K-84 and another antagonist JH-l was better than K-84 alone in controlling some Agrobacterium strains. Strain K-84 surprisingly controlled some resistant Agrobacterium strains when heavy concentrations of K-84 were used. Strain K-84 could control sensitive strains of Agrobacterium up to 48 hr. after wounds were inoculated with the pathogen at te...

UEDA, SEINOSUKE (Kyushu University, Fukuoka, Japan), AND HARUYOSHI KONO. Polysaccharide produced by the genus Pullularia. II. Trans-a-glucosidation by acetone cells of Pullularia. Appl. Microbiol. 13:882-885. 1965.-Acetone cells of Pullularia sp. were incubated with maltose, and the saccharides produced were fractionated on a charcoal column. The fractions were subjected to paper-chromatographi...
متن کاملBiological Control of the Crown Gall Diseases
Six different strains of crown gall bacteria were tested to determine whether the commonly used biocontrol strain, K-84, would present them from infecting the paradox hybrid. Previous research showed that K-84 was highly effective in preventing crown gall infections of English root stock. There was considerable variability among the six strains in ability to cause disease. One of the strains di...
