Abstract

Carotenoid composition in leaves of normal, lycopenic and ζ-carotenic mutants of Zea mays were investigated. In lycopenic leaves, in addition to lycopene, phytoene, phytofluene, δ- and γ-carotene, trace amounts of α- and β-carotene and antheraxanthin were identified. Low light promoted accumulation of α- and β-carotene; high light brought about an increase in antheraxanthin content. In the leaves of the ζ-carotenic mutant, phytoene, phytofluene and ζ-carotene were synthesized. Illumination of low intensity stimulated carotenoid synthesis to a slight extent. Relative amounts of carotenoid components were essentially the same as in etiolated material, except for a small increase in cis-ζ-carotene. Under high intensity illumination, carotenoids were rapidly destroyed.
