Light requirement for shoot regeneration in horseradish hairy roots.
Hairy roots of horseradish (Armoracia rusticana) were induced by inoculation with Agrobacterium rhizogenes harboring Ri plasmid and cultured on phytohormone-free Murashige and Skoog medium after eliminating the bacteria. Hairy roots grew vigorously and sometimes formed yellowish calli under dark conditions. On the other hand, growth of hairy roots stopped after several weeks of culture with lig...
متن کاملEssential Oils from Hairy Root Cultures and Field Cultivated Roots of Valerian (Valeriana sisymbriifolium)
Background: Plant cell cultivations are considered as an alternative to agricultural processes for producing valuable phytochemicals (secondary metabolites). The use of plant cell cultures has overcome several inconveniences for the production of secondary metabolites. Objective: The essential oils isolated from roots of 24-month-old field grown valerian (Valeriana sisymbriifolium) and hairy r...
متن کاملPeroxidase Isoenzymes from Horseradish Roots
The reactivity of histidine in horseradish peroxidase isoenzymes Al and C was determined by titrating with diazonium-lH-tetrazole. No exposed histidine residue was detected in the native isoenzymes. Upon removal of the heme prosthetic group, however, all three histidine residues became titratable. Studies with p-chloromercuribenzoate and 14C-iodoacetamide indicated that the 6 half-cystine resid...
متن کاملPeroxidase Isozymes from Horseradish Roots
Seven peroxidase isozymes were isolated from horseradish roots and purified to homogeneity as ascertained by chromatography, ultracentrifugation, and polyacrylamide disk electrophoresis. Purification procedures included ammonium sulfate precipitation and column chromatography on carboxymethyl and diethylaminoethyl cellulose. Peroxidase activity in the seven isozymes accounted for 86% of the act...
