Abstract
Besides the chlorophylls carotenoids also play an important role in the photosynthetic process. The two main functions of carotenoids in plants are light-harvesting and protection against harmful effects of excess light energy (Larkum and Barrett, 1983; Siefermann-Harms, 1985). Other functions as components of the electron transport chain and structural elements of the photosynthetic apparatus are discussed (Mathis, 1987; Senger and Strassberger, 1978). The carotenogenic pathway comprises the formation of C-40 tetraterpenoids starting from mevalonate. Later steps involve dehydrogenase, isomerase and cyclase activities leading to the cyclic carotenes and oxidation-reactions which yield the various xanthophylls.
