Аннотация: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
