Abstract
Methods for increasing levels of provitamin D3 and/or vitamin D3 in plants are described. Tomato plants were genetical modified resulting in decreased activity of 7-dehydrocholesterol reductase.
Claims13
A method of improving provitamin D3 levels in a plant, the method comprising reducing activity of 7-dehydrocholesterol reductase (7-DR) in the plant.
The method of any preceding claim further comprising exposing the plant or a part of the plant to UV-B radiation.
The method of any preceding claim wherein the plant carries a mutation which increases the penetration of UV-B light into fruit.
The method of any preceding claim further comprising processing the plant or a part of the plant to obtain 7-DHC and/or vitamin D3.
A genetically altered plant, part thereof or plant cell, wherein the plant, part thereof or plant cell has reduced activity of 7-dehydrocholesterol reductase.
