Zusammenfassung
In higher plants the light energy is captured by the photosynthetic pigments that are bound to photosystem I and II and their light-harvesting complex (LHC) subunits. In this study, we examined the photodynamic changes within chlorophyll-protein complexes in the thylakoid membrane of Arabidopsis thaliana leaves adapted to low light and subsequently exposed to light stress. Chlorophyll-protein complexes were isolated using sucrose density gradient centrifugation and blue-native polyacrylamid gel electrophoresis (BN-PAGE). Proteome analysis was performed using SDS-PAGE, HPLC, and high resolution mass spectrometry. We identified several rarely expressed and stress-induced chlorophyll-binding proteins, showed changes in localization of early light-induced protein family and LHC protein family members between different photosynthetic complexes and assembled/disassembled subcomplexes under light stress conditions and discuss their role in a variety of light stress-related processes
