Somatic 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...
متن کاملComposite Medicago truncatula plants harbouring Agrobacterium rhizogenes-transformed roots reveal normal mycorrhization by Glomus intraradices
Composite plants consisting of a wild-type shoot and a transgenic root are frequently used for functional genomics in legume research. Although transformation of roots using Agrobacterium rhizogenes leads to morphologically normal roots, the question arises as to whether such roots interact with arbuscular mycorrhizal (AM) fungi in the same way as wild-type roots. To address this question, root...
متن کاملIsolation and Characterization of Agrobacterium rhizogenes from the Root Nodules of Some Leguminous Plants
A total of 57 colonies of Agrobacterium species was isolated from the root nodules of five different leguminous plant namely Pisum sativum, Sesbania rostrata, Vigna mungo, V. radita and V. ungiculata by using yeast extract mannitol agar (YEMA). All the isolated colonies were belonged to Agrobacterium species. The isolated bacteria were characterized and identified as Agrobacterium rhizogenes ba...
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...
