Testing of planting material for freedom from phytopathogenic bacteria is an important,
although not exclusive, method for control of bacterial diseases of plants. Ideally, pathogen …

The common use of Agrobacterium as a gene vector for plants has somewhat obscured the
fact that this bacterium remains an important plant pathogen. Pathogenic strains of the …

A simple PCR protocol was developed for identifying Agrobacterium as the causal agent of
the tumours produced by this bacterium in plant material. The sensitivity of this method was …

Agrocin-minus mutants of nontumorigenic Agrobacterium vitis strain F2/5 controlled grape
crown gall as well as the wild-type strain, indicating that agrocin is not a major factor in the …

A total of 851 bacterial isolates from the xylem sap of grapevines grown in Nova Scotia,
Canada, were purified and screened for in vitro antagonistic activity against a range of …

For almost 40 years, Australian researchers have been part of an international group of
scientists who have studied graft-transmitted disorders of the grapevine. The Australian wine …

Nach der Antreibphase wurde Kallusmaterial von Stecklingen der Sorten Albana,

Relative levels of crown gall susceptibility were determined in 43 Vitis genotypes by
inoculating with a diverse set of Agrobacterium vitis strains and measuring gall size and the …

Nontumorigenic Agrobacterium vitis strain F2/5 is able to prevent crown gall caused by
tumorigenic A. vitis on grape but not on other plant species such as tobacco. Mutations in a …

Populations of A. vitis were monitored within 1 year. Starting in the middle of May, the
population density of A. vitis was screened every week in all parts of 2-year-old Müller …
