Abstract
Fagopyrum tataricum Gaertn (tartary buckwheat) is an excellent medicinal and nutrient-rich crop. It has a high content of rutin and other phenolic compounds. An experiment was conducted to investigate in vitro production of phenolic compounds from hairy root culture of tartary buckwheat. Hairy root growth was promoted by increasing culture time in MS medium. The highest hairy root growth reached up to 11.2 g/l dry weight at 18 d after placement. Transformation was confirmed by PCR using rol genes, rol A (304 bp), B (797 bp), C (550 bp), and D (1035 bp) genes which is transferred into hairy roots from the Ri-plasmid in Agrobacterium rhizogenes and is responsible for the induction of hairy root from plant species. Rutin, quercetin, (−) epicatechin, (−) catechin hydrate, gallic acid, ferulic acid, chlorogenic acid, and caffeic acid were identified both in hairy and wild type roots of tartary buckwheat. The main compound found in the both types of root was epicatechin followed by rutin. The concentration of phenolic compounds in the hairy roots of tartary buckwheat was several-fold higher compared with wild type roots of same species. Our results indicate that hairy root culture of F. tataricum is a valuable alternative approach for the production of phenolic compounds.
