Quantification of cyclic electron flow around Photosystem I in spinach leaves during photosynthetic induction
The variation of the rate of cyclic electron transport around Photosystem I (PS I) during photosynthetic induction was investigated by illuminating dark-adapted spinach leaf discs with red + far-red actinic li...

Chapter
Carotenoids
Carotenoid pigments provide fruit and flowers with distinctive red, orange and yellow colors and a number of aromas, which make them commercially important in agriculture, food manufacturing and the cosmetic i...

A simple chlorophyll fluorescence parameter that correlates with the rate coefficient of photoinactivation of Photosystem II
A method of partitioning the energy in a mixed population of active and photoinactivated Photosystem II (PS II) complexes based on chlorophyll fluorescence measurements is presented. There are four energy flux...

Chapter
The Role of Carotenoids in Energy Quenching
Photoprotection remains one of the most challenging and complex areas for research in photosynthesis. Co** with a wide range of adverse environmental conditions, especially full sunlight, is central to plant...

Photoprotection in a zeaxanthin- and lutein-deficient double mutant of Arabidopsis
When light absorption by a plant exceeds its capacity for light utilization, photosynthetic light harvesting is rapidly downregulated by photoprotective thermal dissipation, which is measured as nonphotochemic...

Antisense inhibition of the beta-carotene hydroxylase enzyme in Arabidopsis and the implications for carotenoid accumulation, photoprotection and antenna assembly
The xanthophylls are oxygenated carotenoids and are important structural components of the photosynthetic apparatus. Xanthophylls contribute to the assembly and stability of light-harvesting complex apoprotein...

On the Respective Roles of the Various Xanthophylls During Seedling Development and High Light Stress in Arabidopsis
Six hundred different naturally occurring carotenoids have been identified to date and this diversity is reflected in the composition of the photosynthetic apparatus of different bacterial and algal classes. H...
