Thylakoid Membrane Remodeling during State Transitions inArabidopsis 

Abstract: Adaptability of oxygenic photosynthetic organisms to fluctuations in light spectral composition and intensity is conferred by state transitions, short-term regulatory processes that enable the photosynthetic apparatus to rapidly adjust to variations in light quality. In green algae and higher plants, these processes are accompanied by reversible structural rearrangements in the thylakoid membranes. We studied these structural changes in the thylakoid membranes of Arabidopsis thaliana chloroplasts using atomic … Show more

“…For growth to occur, photosynthesis must be greater than respiration. This result was in agreement with previous findings by Fosket (1994) and Chuartzman et al (2008) they mentioned that reduce plant stresses improve the plants use of available resources. The changes in plants morphology induced by UV may affect competition for light (Barnes et al 1988).…”

“…In this context, it is worth emphasizing that increased membrane folding, caused by the loss of light-induced protein phosphorylation, has been observed in Arabidopsis (Fristedt et al, 2009). Our observation that nonphosphorylated LHCII complexes, which do not contain zeaxanthin, can be involved in the formation of the hydrogen bond network between adjacent lipid-protein membranes fits the concept of dynamic reorganization of the chloroplast membrane architecture, which involves fusion and fission events that occur between the nonappressed and appressed thylakoid membranes (Chuartzman et al, 2008). On the other hand, the fact that the zeaxanthincontaining and partially phosphorylated LHCII pool has a much higher affinity to form lamellar aggregated structures in the lipid phase, as demonstrated in this work, seems also to have a pronounced consequence from the physiological standpoint.…”

“…Thus, the flexible nature of the overall thylakoid membrane seems to be key for initiation of PSII repair processes. The capability of the thylakoid membrane system for massive structural reorganizations was also shown by atomic force microscopy and scanning electron microscopy studies [54]. It is noteworthy that the architectural changes mentioned above are not the only control point for the activation of the PSII repair cycle.…”
