The thermostability of photosystem II photochemistry is related to maintenance of thylakoid membranes organization
Original language description
For higher plant photosynthetic reactions, responses to the temperature changes are important, particularly if we consider global warming and the increasing frequency of extreme temperature fluctuations. High temperature stress decreases photosynthetic assimilation through the inactivation of photosystem II (PSII), the most heat-sensitive component of the oxygen-evolving complex. We have recently found higher thermostability of spruce PSII photochemistry compared to such control plants as Arabidopsis species and barley. In this work, we have therefore attempted to describe the causes of this effect on the level of the organization of pigment?protein complexes (PPCs) in spruce thylakoid membranes using circular dichroism (CD) spectroscopy. We have confirmed higher maximum efficiency of PSII photochemistry (FV/FM) for spruce needles in comparison to barley leaves. Temperature-dependent CD spectra have also demonstrated higher (by about 6°C) PSII thermostability of chiral macro-organizati
