Transformation of several species of higher plants by agrobacterium rhizogenes: Sexual transmission of the transformed genotype and phenotype
The T-DNA of the Ri plasmid from Agrobacterium rhizogenes is compatible with the regeneration of whole plants from genetically transformed roots and is transmitted through meiosis to the progeny ofExpand

Nucleotide sequence analysis of TL-DNA of Agrobacterium rhizogenes agropine type plasmid. Identification of open reading frames.
We have determined the nucleotide sequence of the Ri TL-DNA region from an Agrobacterium rhizogenes agropine-type plasmid using subcloned regions from the essentially identical Ri TL-DNAs fromExpand

Agrobacterium rhizogenes inserts T-DNA into the genomes of the host plant root cells
Agrobacterium rhizogenes, which induces hairy root disease of dicotyledonous plants1, is closely related to Agrobacterium tumefaciens, the causative agent of crown gall disease1–3. Virulence in bothExpand

Homology-dependent DNA Transfer from Plants to a Soil Bacterium Under Laboratory Conditions: Implications in Evolution and Horizontal Gene Transfer
DNA transfer was demonstrated from six species of donor plants to the soil bacterium, Acinetobacter spp. BD413, using neomycin phosphotransferase (nptII) as a marker for homologous recombination.Expand

Genetic transformation of Tylophora indica with Agrobacterium rhizogenes A4: growth and tylophorine productivity in different transformed root clones
We have developed an efficient transformation system for Tylophora indica, an important medicinal plant in India, using Agrobacterium rhizogenes strains LBA9402 and A4 to infect excised leaf and stemExpand

Betaine use by rhizosphere bacteria: genes essential for trigonelline, stachydrine, and carnitine catabolism in Rhizobium meliloti are located on pSym in the symbiotic region.
Rhizobium meliloti is known to use betaines synthesized by its host, Medicago sativa, as osmoprotectants and sources of energy. It is shown in the present report that the symbiotic megaplasmid (pSym)Expand

Common evolutionary origin of the central portions of the Ri TL-DNA of Agrobacterium rhizogenes and the Ti T-DNAs of Agrobacterium tumefaciens
Analysis of published sequences for Ri TL-DNA (root-inducing left-hand transferred DNA) of Agrobacterium rhizogenes revealed several unsuspected structural features. First, Ri TL-DNA genes areExpand

Changes in morphological phenotypes and withanolide composition of Ri-transformed roots of Withania somnifera
Developmental variability was introduced into Withania somnifera using genetic transformation by Agrobacterium rhizogenes, with the aim of changing withasteroid production. Inoculation of W.Expand

Survival of plant seeds, their UV screens, and nptII DNA for 18 months outside the International Space Station.
The plausibility that life was imported to Earth from elsewhere can be tested by subjecting life-forms to space travel. Ultraviolet light is the major liability in short-term exposures (Horneck etExpand
