Abstract: | These studies report the development of an efficient technique for large-scale cultivation of fast-growing hairy root culture systems for production of bioactive isoflavones. Trifolium pratense L. is an important source of pharmaceutically important isoflavones with immense health care applications. Trifolium pratense was transformed using different strains of Agrobacterium rhizogenes for hairy root induction and establishment of hairy root rhizoclones. Selected fast-growing rhizoclones of T. pratense were evaluated for their growth and isoflavone production. This study is the first report of stable production of isoflavones through successive culture passages from transformed hairy-root rhizoclones of T. pratense. One of the fast-growing hairy-root rhizoclones 2364A displayed significantly higher accumulation of all four pharmaceutically important isoflavones, 8.56 mg (gdw)?1 of daidzein, 2.45 mg (gdw)?1 of genistein, 15.23 mg (gdw)?1 of formononetin, and 1.10 mg (gdw)?1 of biochanin A, compared to other rhizoclones. |
