Lutein, Anthocyanin and Xanthophyll Cycle Components in Wheat (Triticum aestium) Flag Leaves Under high Light and high Temperature Conditions

Santosh Kumari

Abstract :

Non photochemical quenching (NPQ) decreased in wheat flag leaf under high light and at a temperature 5°C higher than normal growth conditions. The accumulation of the xanthophyll cycle carotenoids and zeaxanthin particularly indicated pH dependent energy dissipation (qE) a major component of NPQ. Neoxanthin and zeaxanthin served important functions as an antioxidant in the lipid phase of the memane and are likely to act as key components in the memory of the chloroplast with respect to preceding photo–oxidative stress in next generation even under low light and normal temperature conditions.
