First Description of Crown Gall Disease on Ginseng [PDF]

The Plant Pathology Journal, 2008
In March of 2003, tumors (galls) were observed on ginseng seedling roots in ginseng seedbeds at Yeoju, Gyeonggi province, Korea. Symptoms were spherical or galls with about 0.5-1.0 cm in diameter formed on the upper through middle parts of the primary roots.

Use of Chitosan to Control Crown Gall Disease

Plant Pathology Journal, 2015
A B S T R A C T The antibacterial activity of chitosan solution against Agrobacterium tumifaciens was investigated in this study. The in vitro antibacterial effect of chitosan against A. tumifaciens was affected by chitosan concentrations, pH value, concentration of acetic acid used to dissolve chitosan and incubation time.

Expression of a crown gall biological control phenotype in an avirulent strain of Agrobacterium vitis by addition of the trifolitoxin production and resistance genes

BMC Biotechnology, 2002
Background Agrobacterium vitis is a causal agent of crown-gall disease. Trifolitoxin (TFX) is a peptide antibiotic active only against members of a specific group of α-proteobacteria that includes Agrobacterium and its close relatives. The ability of TFX

Canopy position and tree size structure the distribution of honeydew‐producing scale insects (Hemiptera: Coccoidea) in a temperate hardwood forest

Ecological Entomology, EarlyView.
Scale insect abundance peaked in the upper canopy of sugar maples. Parthenolecanium peaked on older internodes; Lepidosaphes on the current leader. Internodes longer than the previous carried more scales; wider ones fewer. Abstract Forest canopies are vertically stratified habitats in which microclimate and host tissue quality vary with height.
