Hormone genes and crown gall disease

Trends in Biochemical Sciences, 1987
Abstract The essential aspects of tumor induction by Agrobacterium tumefaciens are now understood; the bacteria transfer genes coding for enzymes of auxin and cytokinin biosynthesis into plant cells, and increased production of these hormones is responsible for continued, uncontrolled growth and for suppression of root and shoot differentiation ...

Efficacy of native antagonistic bacterial isolates in biological control of crown gall disease in Egypt

Annals of Agricultural Sciences, 2013
In vitro analyzing the antagonistic activity of seventy native bacterial isolates towards plant tumorigenic Agrobacterium tumefaciens resulted in a selection of eight potential biocontrol agents. These isolates were screened for their antagonistic effect

THE CROWN‐GALL DISEASE OF NURSERY STOCKS

Annals of Applied Biology, 1924
Summary.An account is given of the galls (“crown‐gall”) found on layered apple stocks and on seedling apple trees raised at the East Mailing Fruit Research Station.On the layered stocks the galls arise most frequently at the .base of the stocks, i.e.

Crown Gall Disease and Prospects for Genetic Manipulation of Plants

Science, 1982
Agrobacterium tumefaciens incites crown gall tumors when bacterial DNA integrates into plant nuclear DNA. Plant cells can express these integrated bacterial genes. Following insertion of desired genes into bacterial DNA using recombinant DNA techniques, this system permits introduction of these new genes into plant DNA.

Crown gall disease

Nature, 1979
Agrobacterium tumefaciens induces tumours in dicotyledonous plants by transferring part of a large bacterial plasmid to the eukaryotic cell. As well as disrupting control of cell division, the transferred DNA determines the synthesis in transformed tissue of novel amino acid compounds which serve as specific substrates for the bacterium.

Agrobacterium biology and crown gall disease

2006
The crown gall tumors produced in dicotyledonous plants by Agrobacterium tumefaciens results from the introduction of a segment of DNA (T-DNA), derived from its tumor-inducing (Ti) plasmid, into plant cells at the infected site. This disease can cause significant economic losses in perennial crops worldwide.

Crown Gall of Grapevine: Disease Management Considerations

1987
Crown gall can be a serious disease on grapevine often causing extensive losses. Infected vines show reduced shoot growth and portions of the vine apical to the galls often die. Although the majority of galling is usually present within 12 to 15 cm of the soil line, aerial galling may extend a meter or more up the trunks and into wood that is at least ...

Morphogenic determinants as Exemplified by the Crown-gall Disease

1976
The autonomous tumors (crown-gall) and organoid galls induced in many higher plants on infection with bacteria of the genus Agrobacterium provide unique experimental material with which to study self-sustaining changes in developmental and biosynthetic capacity.
