Ti plasmid coded protein in Agrobacterium tumefaciens

Creator:: Engelgau, Michael Maurice
Abstract:: Agrobacterium tumefaciens is a plant pathogenic bacteria which incites crown gall tumors. Although virulence has been associated with a 97-156 Mdalton "tumor-inducing" (Ti) plasmid, few potential plasmid gene products have been identified. The objective of this study was to identify plasmid-coded gene products through a comparison of protein fingerprints of...

Molecular factors that influence host range and virulence of A. tumefaciens

Creator:: Castle, Linda A.
Abstract:: Agrobacterium tumefaciens is a common soil bacterium that causes crown gall disease on many dicotyledonous plant species. It has been exploited for use in genetic engineering because it is able to promote transfer of any DNA segment to plant chromosomes. Many molecular factors in both the plant and bacterium contribute...

Transmission of plant pathogenic bacteria and a bacteriophage of Agrobacterium tumefaciens (Smith and Townsend) Conn by a saprozoic nematode, Diplogaster lheriteiri Maupas

Creator:: Chantanao, Aroon
Abstract:: A saprozoic nematode, Diplogaster lheriteiri Maupas 1919, was studied to determine its relationship to the plant pathogenic bacteria, Agrobacterium tumefaciens (Smith and Townsend) Conn., Erwinia amylovora (Burrill) Winslow et al., Erwinia carotovora (Jones) Holland, Pseudomonas phaseolicola (Burk. ) Dows., Xanthomonas campestris (Pam. ) Dows. and to a phage of A....

Host range, serological and electron microscope studies of phages of Agrobacterium tumefaciens (Smith and Townsend) Conn

Creator:: Buangsuwon, Pairoj
Abstract:: Phages of crown gall bacteria were among the first to be isolated and certain properties of these phages have been studied by a number of investigators. However, several important characteristics have not been studied in detail. The present investigation was made in order to determine the major sources of phages...

Transformation of alfalfa using Agrobacterium tumefaciens

Creator:: Gelford, Inga L.
Abstract:: Agrobacterium tumefaciens, the causative agent of crown gall disease, does not readily infect commercial varieties of alfalfa (Medicago sativa). Cloned virulence genes from the megaplasmid pTiBo542 have been shown to enhance Agrobacterium host range and infectivity on dicotyledonous plants. To obtain a gene transfer system for commercial alfalfa cultivars, an...

Functional domains of Agrobacterium tumefaciens single-stranded DNA binding protein VirE2

Creator:: Dombek, Priscilla Emily
Abstract:: Agrobacterium tumefaciens is a gram-negative soil bacterium that causes crown gall tumors on dicotyledenous plants. The transferred DNA (T-DNA) portion of the A. tumefaciens tumor-inducing (Ti) plasmid enters infected plant cells and integrates into plant nuclear DNA. The T-DNA is accompanied into plant cells by the VirD2 endonuclease covalently attached...

A survey of Agrobacterium strains associated with Georgia pecan trees and an immunological study of the bacterium

Creator:: Bouzar, Hacène
Abstract:: Crown gall was found in numerous pecan orchards in Georgia. In some instances, 60% of the trees were diseased. Galled trees were less vigorous than noninfected trees. Among the pathogenic Agrobacterium strains isolated from 18 galled trees from six counties, biovar 1 strains predominated and most were sensitive to agrocin...

Silencing of Agrobacterium tumefaciens T-DNA oncogenes by cosuppression

Creator:: Lee, Hyewon
Abstract:: We have developed crown-gall resistant transgenic plants capable of suppressing Agrobacterium tumefaciens T-DNA oncogenes. Crown gall tumors result from overproduction of auxin and cytokinin in plant cells transformed by A. tumefaciens. High phytohormone levels result from expression of two auxin biosynthetic genes, tryptophan monooxygenase (iaaM) and indole acetamide hydrolase (iaaH),...

Silencing the Agrobacterium tumefaciens oncogenes

Creator:: Pitrak, Jennifer
Abstract:: Crown gall disease is an agricultural problem caused by the soil-borne bacterium, Agrobacterium tumefaciens. A. tumefaciens oncogenes cause transformed plant cells to overproduce the hormones, auxin and cytokinin. High hormone levels cause unorganized plant cell growth resulting in a gall. Control of crown gall disease is difficult because after plant...
