Structures of UV-B Induced Sunscreen Pigments of the Scots Pine (Pinus sylvestris L.)

摘要

Owing to increased global UV-B radiation, a consequence of ozone destruction in the stratosphere, living beings need effective protection mechanisms for survival. Most experiments investigating the effect of UV-B radiation have been carried out on cultivated plants, whilst only a few have been performed on trees. Here we report on the structture of sunscreen pigments formed in Scots pine seedlings (Pinus sylvestris L.) specifically as a reaction to UV-B irradiation.
