additional information transgenic enzyme-overexpressing plants show accumulation of light-harvesting complexes and reduced beta-carotene levels compared to wild-type plants, while it is increased in enzyme-deficient chlorina-1 mutant plants, in overexpressing plants the chlorophyll a/b ratio remains low under high-light conditions in contrast to wild-type plants Arabidopsis thaliana
