Article history: Received on: 05/11/2012 Revised on: 29/11/2012 Accepted on: 18/12/2012 Available online: 28/02/2013 Anisodus acutangulus hairy roots were grown in N6 medium which was optimal for growth and alkaloid production. The cell biomass and alkaloid yield reached 2.7 g l and 3.9 mg l (dry weight) respectively in sucrose medium, higher than those obtained in other carbon source media. 90...
Hyoscyamus albus hairy roots with/without an exogenous gene (11 clones) were established by inoculation of Agrobacterium rhizogenes. All clones cultured under iron-deficient condition secreted riboflavin from the root tips into the culture medium and the productivity depended on the number and size of root tips among the clones. A decline of pH was observed before riboflavin production and root...
Phenylethanoids are a group of natural water-soluble compounds with high biological value, which could potentially be commercially produced by hairy root cultures. Thus, we have examined the capacity of transformed root cultures of Devil's claw (Harpagophytum procumbens) to accumulate four phenylethanoid glycosides -beta-OH-verbascoside, verbascoside, leucosceptoside A, and martynoside--in shak...
Momordica charantia (Cucurbitaceae) is an important vegetable and also medicinal crop which produces the bioactive compounds for various biological activities with potential uses in human health. The present investigation relates to elicitors of jasmonic acid (JA) and salicylic acid (SA) to enhance biomass accumulation and phenolic compound production in hairy root cultures of M. charantia. Hai...
Agrobacterium rhizogenes ATCC 15834 wild type strain was transformed with the binary vector pBI121 using the heat shock method. The transformed Agrobacterium was then tested for virulence through tobacco leaf explant transformation. Compared to the non-transformed Agrobacterium, the transformed Agrobacterium showed reduced virulence, producing signifi cantly lower number of hairy roots in tobac...
A lignan, lariciresinol, is an important efficacious compound for the antiviral effect of Isatis indigotica, a widely used herb for the treatment of colds, fever, and influenza. Although some rate-limiting steps of the lariciresinol biosynthetic pathway are well known, the specific roles of gene family members in I. indigotica in regulating lariciresinol production are poorly understood. In the...
