Tropane alkaloids and toxicity of Convolvulus arvensis.
Horses in a few, localized northern Colorado pastures exhibited weight loss and colic. At post mortem, intestinal fibrosis and vascular sclerosis of the small intestine was identified. The pastures where the affected horses grazed were overrun by field bindweed (Convolvulus arvensis). Bindweed from the pasture was found to contain the tropane alkaloids tropine, pseudotropine, and tropinone and ...
متن کاملTransformation of Catalpa ovata by Agrobacterium rhizogenes and phenylethanoid glycosides production in transformed root cultures.
Transformed root cultures of Catalpa ovata were established following shoots infection with four agropine strains of Agrobacterium rhizogenes. Frequency of root formation was dependent on the bacterial strain and the presence of acetosyringone in the incubation medium. It is the first report concerning the possibility of transforming Catalpa ovata by A. rhizogenes. Both transformed and untransf...
متن کاملDraft Genome Sequence of Agrobacterium rhizogenes Strain NCPPB2659
This work reports the draft genome sequence of Agrobacterium rhizogenes strain NCPPB2659 (also known as strain K599). The assembled genome contains 5,277,347 bp, composed of one circular chromosome, the pRi2659 virulence plasmid, and 17 scaffolds pertaining to the linear chromosome. The wild-type strain causes hairy root disease in dicots and has been used to make transgenic hairy root cultures...

متن کاملSomatic Embryogenesis and Plantlet Regeneration from Hairy Roots Transformed by Agrobacterium rhizogenes in Panax quinquefolium L
Here, efficient plantlet regeneration via somatic embryogenesis from Panax quinquefolium hairy roots was reported. Callus development was optimal on MS medium containing 2,4-dichlorophenoxyacetic acid (1 mg l) and -naphthalene acetic acid (1 mg l). After a 4-week growth, calli were transferred onto MS medium with different combinations of plant growth regulators (PGRs). The highest embryogenesi...
