Abstract
SAN-9789 (norflurazon) is a bleaching herbicide, and its effect on carotenoid biosynthesis is well known (Moreland 1980). As the carotenoid precursors phytoene and phytofluene are accumulated in SAN-9789 treated cells it is assumed, that the herbicide interfer with the desaturation steps of the biosynthesis (Bartels, Watson 1978). Carotenoids play an important part in photo-protection in the chloroplasts (Krinsky 1978), and the decreased carotenoid contents in SAN-9789 treated cells enhanches the possibility of the occurence of photodestructive reactions.
