UV-B induced accumulation of tocopherol in Arabidopsis thaliana is not dependent on individual UV photoreceptors

Tocopherol is recognised in human nutrition as vitamin E, an important component of a healthy diet.

This paper reports on our research that shows that tocopherols are increased in the model plant Arabidopsis thaliana when exposed to increased levels of UV-B. Increased levels of tocopherols are shown to play a role in UV protection of the plant. However, the accumulation of tocopherols is independent of the photoreceptor activated.

Highlights

• The application of UV-B radiation results in dynamic changes in tocopherol accumulation of plants.
• UV-B exposure led to the accumulation of tocopherol in a photoreceptor-independent manner.
• The accumulation of tocopherol is an important part of plant UV protection.
