Induction of Pseudoactinorhizae by the Plant Pathogen Agrobacterium rhizogenes [PDF]
Plant Physiology, 1992 Infection of Elaeagnus angustifolia cotyledonary wounds by Agrobacterium rhizogenes strain NCPPB 2659 resulted in the formation of pseudoactinorhizae on roots differentiated from callus. These pseudoactinorhizal root nodules were anatomically indistinguishable from the actinorhizae induced by the plant's microsymbiont Frankia.

Differentiation of Phytopathogenic Agrobacterium spp. [PDF]
Pesticidi i Fitomedicina, 2011 Due to the difficulties in differentiation of phytopathogenic Agrobacterium spp. and lack of a standardized protocol, we carried out selection and evaluation of suitable methods based on the bacterial physiological, genetic and pathogenic properties ...

First Report of Crown Gall Caused by Agrobacterium rhizogenes on Korean Raspberry (Rubus crataegifolius) in Korea [PDF]
Research in Plant DiseaseIn July 2022, the occurrence of crown gall was observed on Korean raspberry (Rubus crataegifolius) plants in a field in Gijang-gun, Busan, Korea. The galls appeared irregular in structure and varied in color from milky white to dark brown.

Agrobacterium rhizogenes mutants that fail to bind to plant cells [PDF]
Journal of Bacteriology, 1990 Transposon insertion mutants of Agrobacterium rhizogenes were screened to obtain mutant bacteria that failed to bind to carrot suspension culture cells. A light microscope binding assay was used. The bacterial isolates that were reduced in binding to carrot cells were all avirulent on Bryophyllum diagremontiana leaves and on carrot root disks.

Natural Agrobacterium Transformants: Recent Results and Some Theoretical Considerations
Frontiers in Plant Science, 2017 Agrobacterium rhizogenes causes hairy root growth on a large number of plant species. It does so by transferring specific DNA fragments (T-DNA) from its root-inducing plasmid (pRi) into plant cells. Expression of T-DNA genes leads to abnormal root growth

Cultivar Specificity of Jujube using Agrobacterium rhizogenes [PDF]
HortScience, 1996 Jujube (Ziziphus jujuba), is valued for its fruit, its ornamental quality, and for its use in reforestation. Jujube is considered to be very difficult to root. Five strains of Agrobacterium rhizogenes were tested on eight cultivars of jujube for the induction of roots. Strains of A. rhizogenes used were A4, TR105, AR WT, MT232, and 50.

Genetic manipulation in potato withAgrobacterium rhizogenes
Potato Research, 1986 Infection withAgrobacterium rhizogenes of wounded stems of potato cultivars grown in vitro caused localized prolific root formation (hairy-roots). The cells of these roots contained newly introduced DNA, not detected in normal potato, that was derived fromA. rhizogenes.

Genetic Transformation of Sugar Beet by Agrobacterium Rhizogenes [PDF]
Biotechnology & Biotechnological Equipment, 1995 ABSTRACTThe petioles of four in vitro propagated sugarbeet lines were inoculated with Agrobcterium rhizogenes strains. Hairy roots with different frequency were obtained. Root clones resistant to Km were propagated and included in the regeneration experiment.
