- Abstract
To study biosynthetic abilities of Lithospermum officinale, callus formation from young leaves and stems of the plant was induced on Linsmaier-Skoog medium supplemented with 2,4-D (10−6 M) and kinetin (10−5 M). Maintaining the calli on this medium resulted in polyphenolic compounds production. Their transfer onto White medium containing IAA (10−7 M) and kinetin (10−5 M) resulted in the production of a red naphthoquinonic pigment named shikalkin. Shikalkin production from callus cultures was suppressed on the White medium containing NAA instead of IAA. This observation indicates that both shikalkin and polyphenolic acids biosynthetic pathways exist in the L. officinale callus cells and a regulatory system counterbalances the ratio of shikalkin to polyphenolic acids.
