Can Parietin Transfer Energy Radiatively to Photosynthetic Pigments?

Photosynthetic Pigments in Diatoms

Photosynthetic pigments are bioactive compounds of great importance for the food, cosmetic, and pharmaceutical industries. They are not only responsible for capturing solar energy to carry out photosynthesis, but also play a role in photoprotective processes and display antioxidant activity, all of which contribute to effective biomass and oxygen production. Diatoms are organisms of a distinct ...

Energy Transfer and Photosynthetic Light Harvesting

Quantum Coherence Accelerating Photosynthetic Energy Transfer

We show how long-lasting coherence enhances energy transfer rate in a photosynthetic complex based on an analysis of data collected using a newly developed twocolor electronic coherence photon echo technique and theoretical simulations.

Deregulated chlorophyll b synthesis reduces the energy transfer rate between photosynthetic pigments and induces photodamage in Arabidopsis thaliana.

Chl b is one of the major light-harvesting pigments in land plants. The synthesis of Chl b is strictly regulated in response to light conditions in order to control the antenna size of photosystems. Regulation of Chl b also affects its distribution as it occurs preferentially in the peripheral antenna complexes. However, it has not been experimentally shown how plants respond to environmental c...
