Effect of Lipids on Violaxanthin and Diadinoxanthin De-Epoxidation
Violaxanthin (Vx) and diadinoxanthin (Ddx) de-epoxidation are light dependent steps in one of the most important photoprotecting processes called respectively violaxanthin and diadinoxanthin cycle. Violaxanthi...

The Oligomeric Antenna of the Diatom P. tricornutum — Localisation of Diadinoxanthin Cycle Pigments
In the present work a thorough examination of the oligomeric antenna of P. tricornutum was performed. Solubilisation of thylakoids with n-dodecyl β-d-maltoside in combination with gelfiltration and sucrose densit...

Evidence for a Fast, Xanthophyll Cycle Independent NPQ Mechanism in the Diatom C. meneghiniana
for the diatom Phaeodactylum tricornutum it was reported that non-photochemical quenching (NPQ) strictly depends on the de-epoxidation state of the xanthophyll cycle (XC) pigment pool. In our present study we sho...

In Mantoniella Squamata Deepoxidized Xanthophyll Cycle Pigments Show a Tighter Pigment Protein Coupling than the Respective Epoxidized Forms
The prasinophycean alga Mantoniella squamata uses in vivo an incomplete violaxanthin cycle with antheraxanthin accumulating during periods of strong illumination (1). Antheraxanthin enhances thermal dissipation o...

Multiple Short Term Effects of UV-B Radiation on the Diatom Phaeodactylum Tricornutum
Increases in UV-B irradiance lead to many specific damaging effects upon the plants including damage of the thylakoid membrane, partial inhibition of PS II, decrease of chloroplast ATPase activity, loss of enz...

Picosecond Time Resolved Analysis of the Fast and Slow Reversible Non-Photochemical Chlorophyll Fluorescence Quenching
Photosystem II, which is a potential target of adverse effects of supersaturating light, is strongly dependent on a mechanism, which allows to switch over between efficient photochemical energy conversion at l...
