Nopaline was inspected in the crown gall and showed that the transformation was successfull. L6 line, can secret red naphthoquinone pigments that are shikonin derivatives on phytohormone free 6,7-V medium, was selected from other lines on different basic phytohormone free media(MS, 6,7-V, WP, B5).The content of shikonin in the crown gall was 1 18%(dry tissue).The study showed that crown gall tissue culture of L.erythrorhizon was a new method to produce shikonin.展开更多
