Biodiversity of NPQ

Reimund Goss, +1 more
- 01 Jan 2015 - 
TL;DR: The present day knowledge about NPQ in higher plants and different algal groups is summarized with a special focus on the molecular mechanisms that lead to the structural rearrangements of the antenna complexes and enhanced heat dissipation.
Journal ArticleDOI

Molecular dynamics of the diatom thylakoid membrane under different light conditions

Bernard Lepetit, +3 more
- 01 Mar 2012 - 
TL;DR: A working hypothesis of the domain formation of the diatom thylakoid membrane is presented to highlight the most prominent differences of heterokonticThylakoids in comparison to vascular plants and green algae during the acclimation to low and high light conditions.
Journal ArticleDOI

Evidence for the Existence of One Antenna-Associated, Lipid-Dissolved and Two Protein-Bound Pools of Diadinoxanthin Cycle Pigments in Diatoms

Bernard Lepetit, +4 more
- 01 Dec 2010 - 
TL;DR: The characterization of intact cells, thylakoid membranes, and pigment protein complexes by absorption and low-temperature fluorescence spectroscopy showed that the FCPs contain certain amounts of protein-bound diadinoxanthin cycle pigments, which are not significantly different in high-light andLow light cultures.
Journal ArticleDOI

Ultrafast fluorescence study on the location and mechanism of non-photochemical quenching in diatoms.

Yuliya Miloslavina, +6 more
- 01 Oct 2009 - 
TL;DR: Intact cells of the diatoms Cyclotella meneghiniana and Phaeodactylum tricornutum, which show different NPQ induction kinetics under high light illumination, were investigated by picosecond time-resolved fluorescence under dark and NPQ-inducing high light conditions and revealed that there are two independent sites responsible for NPQ.
Journal ArticleDOI

High light acclimation in the secondary plastids containing diatom Phaeodactylum tricornutum is triggered by the redox state of the plastoquinone pool

Bernard Lepetit, +7 more
- 01 Feb 2013 - 
TL;DR: The results emphasize strong evidence for the existence of a plastid-to-nucleus retrograde signaling mechanism in an organism with plastids that derived from secondary endosymbiosis and underline the central role of the redox state of the PQ pool in the light acclimation of diatoms.
