[1] Strizh I. The mehler reaction as an essential link between environmental stresses and chloroplast redox signaling // Photosynthesis. Energy from the Sun. — TIERGARTENSTRASSE 17, HEIDELBERG, GERMANY,D-69121: TIERGARTENSTRASSE 17, HEIDELBERG, GERMANY,D-69121, 2008. — P. 1343–1346. Oxygen photoreduction in chloroplasts in the Mehler reaction (MR) is one amongst the well-known, but still confusing topics in photosynthesis. Current data on wide range of plant responses triggered by H2O2 accumulated in chloroplasts suggest that the MR plays an important role in stress sensing and redox signaling. We have found that resistance of wheat and oat seedlings to environmental stresses that result in leaf osmotic stress correlate with the lower ability to form superoxide in the locality of photosystem I and higher rate of H2O2 photogeneration. The regulation of the reactive oxygen species generation in the MR may determine plant stress resistance. [ DOI ]
