Example text

Some authors (Rautenkranz et al. 1994; Horemans et al. 2000) presented data supporting the increased transport of Asc from the cytosol to chloroplasts in stressed plants, and thylakoid membranes are able to transport Asc by diffusion (Foyer and Lelandais 1996; Horemans et al. 2000). The unique status of chloroplasts is also related to the relationship of C, N and S assimilation pathways in these organelles that are influenced by a broad spectrum of environmental conditions (Paul and Foyer 2001).

At high Asc concentrations a strong shift of the pH optimum towards higher pH values was observed and DDE was found to be still active at almost neutral pH values, showing very fast and strong response in activity to small pH changes in the thylakoid lumen. It was also shown that the ascorbate affinity is an intrinsic feature of the respective enzyme and does not depend on the nature of the substrate being de-epoxidized. The high affinity of DDE for ascorbate indicates that, even at a limited availability of reduced ascorbate, high enzyme activity is possible at low pH values.

The unique status of chloroplasts is also related to the relationship of C, N and S assimilation pathways in these organelles that are influenced by a broad spectrum of environmental conditions (Paul and Foyer 2001). The complexity of these chloroplast regulations may be emphasize by GSH and salicylic acid (SA) biosynthesis (Kuźniak et al. 2009). The high concentrations of GSH found in the chloroplast could be to some extent dependent on import from the cytosol, although the contributions of the two compartments to GSH formation may vary between different 12 D.
