Decreased photochemical efficiency of Photosystem II following sunlight exposure of shade-grown leaves of avocado (Persea americana Mill.): because of, or in spite of, two kinetically distinct xanthophyll cycles?
This study resolved correlations between changes in xanthophyll pigments and photosynthetic properties in attached and detached shade-grown avocado (Persea americana) leaves upon sun exposure. Lutein epoxide (Lx) was deepoxidized to lutein (L), increasing the total pool by DL over 5 h, whereas violaxanthin (V) conversion to antheraxanthin (A) and zeaxanthin (Z) ceased after 1 h. During subsequent dark or shade recovery, de novo synthesis of L and Z continued, followed by epoxidation of A...[Show more]
