In the present study, five regions (Wonju, Jincheon, Taean, Suncheon, and Kimhae) of South Korea were chosen to isolate A. tumefaciens strains on roses and assess their opine metabolism (agrocinopine, nopaline, and octopine) genes based on PCR amplification. These isolated strains were confirmed as Agrobacterium using morphological, biochemical, and 16S rDNA analyses; and pathogenicity tests, including the growth characteristics of the white colony appearance on ammonium sulfate glucose minimal media, enzyme activities, 16S rDNA sequence alignment, and pathogenicity on tomato (Solanum lycopersicum). Carbon utilization, biofilm formation, tumorigenicity, and motility assays were performed to demarcate opine metabolism genes. -

According to the Convention on Biological Diversity, biotechnology means: “any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use.” Interpreted in this broad sense, the definition covers many of the tools and techniques that are commonplace today in agriculture and food production. If interpreted in a narrow sense to consider only the “new” DNA, molecular biology and reproductive technology, the definition covers a range of different technologies, including gene manipulation, gene transfer, DNA typing and cloning of mammals. -

THOMAS HAYMANt§, AND STEPHEN K. FARRANDt¶ Departments of tPlant Pathology and IMicrobiology, University of Illinois, Urbana, IL 61801 Communicated by Luis Sequeira, September 16, 1991 ABSTRACT The Ti plasmids of Agrobacterium tume- negative regulatory proteins that control sugar catabolic faciens are conjugal elements whose transfer is strongly re- operons in several unrelated bacteria (10). Our findings pressed.

( 1,3-Dicarboxypropyl)-L-Amino Acids in Crown-Gall Tumors Induced by Agrobacterium Tumefaciens Strains 181 and EU6

Physicochemical analysis of the compounds in this fraction showed that they are N2-(1,3-dicarboxypropyl)-L-amino acids derived from neutral and acidic amino acids. Asparagine and glutamine derivatives (asparaginopine and glutaminopine) are the main components. Synthesis of asparaginopine from asparagine, cu-ketoglutarate and NADPH, and degradation of asparaginopine to asparagine have also been demonstrated using enzyme prepared from Pinto bean strain 181 tumor.
