As in other species, rapidly reversible photoprotection (measured as non-photochemical chlorophyll fluorescence quenching) is initiated within the time frame of sun-flecks (minutes), before detectable conversion of violaxanthin to antheraxanthin or zeaxanthin. Photoprotection is stabilized within hours of exposure to strong light by simultaneously engaging the reversible violaxanthin cycle and a slowly reversible conversion of lutein-epoxide to lutein. It is proposed that this lutein 'locks in' a primary mechanism of photoprotection during photoacclimation in this species, converting efficient light-harvesting antennae of the shade plant into potential excitation dissipating centres. It is hypothesized that lutein occupies sites L2 and V1 in light-harvesting chlorophyll protein complexes of photosystem II, facilitating enhanced photoprotection through the superior singlet and/or triplet chlorophyll quenching capacity of lutein. 000040448 536__ $$0G:(DE-Juel1)FUEK257$$2G:(DE-HGF)$$aChemie und Dynamik der Geo-Biosphäre$$cU01$$x0 000040448 588__ $$aDataset connected to Web of Science, Pubmed 000040448 650_2 $$2MeSH$$aAcclimatization: physiology 000040448 650_2 $$2MeSH$$aCircadian Rhythm 000040448 650_2 $$2MeSH$$aElectron Transport 000040448 650_2 $$2MeSH$$aFabaceae: metabolism 000040448 650_2 $$2MeSH$$aFabaceae: physiology 000040448 650_2 $$2MeSH$$aFabaceae: radiation effects 000040448 650_2 $$2MeSH$$aLight 000040448 650_2 $$2MeSH$$aLutein: analogs & derivatives 000040448 650_2 $$2MeSH$$aLutein: metabolism 000040448 650_2 $$2MeSH$$aPhotosynthetic Reaction Center Complex Proteins: physiology 000040448 650_2 $$2MeSH$$aPigments, Biological: metabolism 000040448 650_2 $$2MeSH$$aPlant Leaves: physiology 000040448 650_2 $$2MeSH$$aTrees: physiology 000040448 650_2 $$2MeSH$$aTropical Climate 000040448 650_7 $$00$$2NLM Chemicals$$aPhotosynthetic Reaction Center Complex Proteins 000040448 650_7 $$00$$2NLM Chemicals$$aPigments, Biological 000040448 650_7 $$0127-40-2$$2NLM Chemicals$$aLutein 000040448 650_7 $$2WoSType$$aJ 000040448 65320 $$2Author$$aInga sp. 000040448 65320 $$2Author$$alutein-epoxide 000040448 65320 $$2Author$$aphotoacclimation 000040448 65320 $$2Author$$aphotoprotection 000040448 65320 $$2Author$$aphotosynthesis 000040448 65320 $$2Author$$axanthophyll cycles 000040448 7001_ $$0P:(DE-HGF)0$$aNaumann, M.$$b1 000040448 7001_ $$0P:(DE-HGF)0$$aMartin, J.
