Lutein is needed for efficient chlorophyll triplet quenching

Lutein is the most abundant xanthophyll in the photosynthetic apparatus of higher plants It binds to site L1 of all Lhc proteins whose occupancy is indispensable for protein folding and quenching chlorophyll triplets Thus the lack of a visible phenotype in mutants lacking lutein has been surprising We have re assessed the lut2 1 phenotypes through biochemical and spectroscopic methods …

The Functional Significance of Black Pigmented Leaves

Black pigmented leaves are common among horticultural cultivars yet are extremely rare across natural plant populations We hypothesised that black pigmentation would disadvantage a plant by reducing photosynthesis and therefore shoot productivity but that this trait might also confer protective benefits by shielding chloroplasts against photo oxidative stress CO2 assimilation chlorophyll …

Chloroplast ultrastructure in plants

The chloroplast organelle in mesophyll cells of higher plants represents a sunlight driven metabolic factory that eventually fuels life on our planet Knowledge of the ultrastructure and the dynamics of this unique organelle is essential to understanding its function in an …

nbsp 0183 32 However accessing a dark state such as a radical cation via the triplet state could play a role as demonstrated for the molecular dye R6G It is unlikely that this is a dominant mechanism for the complexes investigated in this study as this would require excitation of a Car triplet state which has a negligible probability under the utilized conditions …

Manipulation of Photoprotection to Improve Plant

Photoprotection is a rather broad term that can be used to cover mechanisms that prevent light energy from inducing damage via the generation of high levels of reactive oxygen species ROS Although ROS are important signaling molecules in plants they can have deleterious effects on photosynthesis and other leaf processes that ultimately will reduce growth and plant fitness …
