Journal ArticleDOI
Non-Photochemical Quenching. A Response to Excess Light Energy
TL;DR: Plants and algae have a love/hate relationship with light; however, too much light can lead to increased production of damaging reactive oxygen species as byproducts of photosynthesis.
Journal ArticleDOI
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.
Journal ArticleDOI
Carotenoid Cation Formation and the Regulation of Photosynthetic Light Harvesting
Nancy E. Holt,Donatas Zigmantas,Donatas Zigmantas,Leonas Valkunas,Xiao-Ping Li,Krishna K. Niyogi,Krishna K. Niyogi,Graham R. Fleming,Graham R. Fleming +8 more
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.
Journal ArticleDOI
Regulation of Photosynthetic Light Harvesting Involves Intrathylakoid Lumen pH Sensing by the PsbS Protein
Xiao-Ping Li,Adam M. Gilmore,Stefano Caffarri,Stefano Caffarri,Stefano Caffarri,Roberto Bassi,Roberto Bassi,Talila Golan,David Kramer,Krishna K. Niyogi +9 more
TL;DR: A bifacial model for the functional interaction of PsbS with photosystem II is proposed, based on the extent of qE inhibition in the mutants, photochemical and nonphotochemical quenching processes of Photosystem II were associated with distinct chlorophyll fluorescence life-time distribution components.
Journal ArticleDOI
PsbS-dependent enhancement of feedback de-excitation protects photosystem II from photoinhibition
TL;DR: Increased qE capacity was associated with decreased photosystem II excitation pressure and changes in the fractional areas of chlorophyll a fluorescence lifetime distributions, but not the lifetime centers, suggesting that qE protects from photoinhibition by preventing overreduction of Photosystem II electron acceptors.
