Pigment production
|
Pigment production |
| Some cell cultures accumulate high
levels of pigments. An example is cultures of Lithospermum erythrorhizon, which produce a red pigment, shikonin, used in cosmetics. Other cell cultures produce anthocyanins,
red or blue flavonoids, |
Callus cultures of Oxalis reclinata are yellow in the light,
but when
they are transferred to the dark, they start producing red anthocyanin
pigments.
