Contributors: Y. Okegawa, T. Long*, M. Iwano, S. Takayama, Y. Kobayashi, S. Covert, T. Shikanai

author keywords: antimycin A; Arabidopsis; ferredoxin; NPQ; PGR5; PSI; cyclic electron transport
MeSH headings : Antimycin A / pharmacology; Arabidopsis / drug effects; Arabidopsis / genetics; Arabidopsis / metabolism; Arabidopsis Proteins / genetics; Arabidopsis Proteins / metabolism; Chloroplasts / metabolism; Cotyledon / metabolism; Electron Transport / physiology; Gene Expression Regulation, Plant; Light; Oxidation-Reduction; Photosynthetic Reaction Center Complex Proteins / genetics; Photosynthetic Reaction Center Complex Proteins / metabolism; Photosystem I Protein Complex / metabolism; Time Factors
TL;DR: It is proposed that a balanced PGR5 level is required for efficient regulation of the rate of antimycin A-sensitive PSI cyclic electron transport, although the rate is probably also regulated by other factors during steady-state photosynthesis. (via Semantic Scholar)
