title: [Protein carbonylation and its role in physiological processes in plants].
abstract: Plant cells produce reactive oxygen species (ROS) continuously as a byproducts of oxygen metabolism and reaction to various environmental stresses. ROS are considered as chemicals inducing damage of cellular components (DNA, lipids and proteins), but also might act as signaling agents. Protein oxidation is one of covalent modification of protein induced by ROS or other products of oxidative stress. Carbonylation of particular amino acid residues (arginine, lysine, treonine or proline) is one of the most commonly occurring oxidative modification of proteins. This modification might lead to alteration in protein activity, its proteolytic breakdown or, in the opposite, aggregate formation. Carbonylated proteins have been identified in many plant species at different stage of growth and development. The analysis of subcellular localization of carbonylated proteins arised the hypothesis on their signaling function. We summarize the current knowledge on the detection of carbonylation protein in plants taking to the account the conditions which may influence their production or removal. We present also their putative role in plant physiology and discuss interaction between ROS and RNS in regulation of protein carbonylation.
