TLDR
All photosynthetic organisms need to regulate light harvesting for photoprotection, and three types of flexible non-photochemical quenching mechanisms have been characterized in oxygenic photosynthesis, algae, and plants: OCP-, LHCSR-, and PSBS-dependent NPQ.About:

Natural strategies for photosynthetic light harvesting
TL;DR: The available knowledge can be used for optimizing light harvesting in both natural and artificial photosynthesis to improve light-driven production processes and explain the main design principles used in nature.
Journal ArticleDOI
Nonphotochemical Chlorophyll Fluorescence Quenching: Mechanism and Effectiveness in Protecting Plants from Photodamage
TL;DR: A novel, emerging technology for assessing the photoprotective “power” of NPQ is described and it is concluded that the minimum requirements for NPQ in vivo are ΔpH, LHCII complexes, and the PsbS protein.
Journal ArticleDOI
Systems and photosystems: cellular limits of autotrophic productivity in cyanobacteria.
TL;DR: The present model describes autotrophic growth in terms of the allocation protein resources among core functional groups including the photosynthetic electron transport chain, light-harvesting antennae, and the ribosome groups to predict adaptation to osmotic stress and lower maximal growth rates.

Physiological Functions of Cyclic Electron Transport Around Photosystem I in Sustaining Photosynthesis and Plant Growth.
Wataru Yamori,Toshiharu Shikanai +1 more
TL;DR: This review summarizes the possible functions and importance of the two pathways of PSI cyclic electron transport and proposes a major pathway mediated by the chloroplast NADH dehydrogenase-like (NDH) complex.

Carotenoid Metabolism in Plants: The Role of Plastids.
TL;DR: This review provides a comprehensive overview of the impact of various types of plastids on carotenoid biosynthesis and accumulation, and discusses recent advances in the understanding of the regulatory control ofCarotenogenesis and metabolic engineering ofcarotenoids in light ofplastid types in plants.

A pigment-binding protein essential for regulation of photosynthetic light harvesting
Xiao-Ping Li,Olle Björkman,Connie Shih,Arthur R. Grossman,Magnus Rosenquist,Magnus Rosenquist,Stefan Jansson,Krishna K. Niyogi +7 more
TL;DR: Results indicate that PsbS, an intrinsic chlorophyll-binding protein of photosystem II, is necessary for nonphotochemical quenching but not for efficient light harvesting and photosynthesis, a finding that has implications for the functional evolution of pigment-binding proteins.

TL;DR: It is experimentally demonstrated that a change in conformation of LHCII occurs in vivo, which opens a channel for energy dissipation by transfer to a bound carotenoid, suggesting that this is the principal mechanism of photoprotection.
Journal ArticleDOI
Photoprotection in an ecological context: the remarkable complexity of thermal energy dissipation.
TL;DR: Zeaxanthin-facilitated, flexible thermal dissipation associated with the PsbS protein and controlled by the trans-thylakoid pH gradient apparently occurs ubiquitously in plants, and can become sustained (and thus less flexible) at low temperatures.

TL;DR: Results indicate that energy transfer from chlorophyll molecules to a chlorophyLLzeaxanthin heterodimer, which then undergoes charge separation, is the mechanism for excess energy dissipation during feedback deexcitation.

The photoprotective molecular switch in the photosystem II antenna
TL;DR: It is suggested how PsbS and xanthophylls may exert control over qE by controlling the affinity of LHCII complexes for protons with reference to the concepts of hydrophobicity, allostery and hysteresis.
