Can we capture redox signaling from chloroplast by modern technologies? // Abstracts of the Society for Experimental Biology Annual Main Meeting 2010. — Prague, Czech Republic, 2010. — P. 302–303. Redox changes are amongst the most important mechanisms that regulate plant growth and development, as well as acclimation and adaptation to the environmental stresses. The primary redox changes occur in chloroplasts under illumination and the most intriguing topic is how these light-derived signals could be converted to the “plant-understandable” signals. It is assumed that generation of the reactive oxygen species (ROS) in chloroplast could induce the signal transduction from the environment through the chloroplast to the nuclei, however these networks are not recognized precisely yet. Today we do now plenty of data concerning to the oxygen photoreduction in chloroplasts in variety species and in different environmental conditions obtained by diverse classical biophysical, biochemical and physiological techniques. Based on the data obtained we can suggest that increase in superoxide photogeneration under environmental stresses may leads to the plant cell death, whereas increase in hydrogen peroxide photogeneration may trigger altering in plant development and adaptation. The stresses that have been tested as well as developmental changes are known to alter membrane integrity, so we can suppose that regulation of superoxide or hydrogen peroxide production is realized by changes in thylakoids membranes. The next step is to find protein targets that could be involved in these phenomena.
