title: [SIGNAL MEDIATORS IN PLANTS RESPONSES AGAINST ABIOTIC STRESSORS: CALCIUM, REACTIVE OXYGEN AND NITROGEN SPECIES].
abstract: The perception of signals of abiotic stressors by plant cells is accompanied by the increase of cytosolic calcium concentration, content of reactive oxygen species (ROS) and nitrogen monoxide (NO) which execute the role of signal mediators at the activation of gene expression, supervising protective reactions. Calcium ions, ROS, and NO are in the multiple functional interactions which provides the intensifying and transduction of signals into genetic apparatus as well as their attenuation. The increase of content, at least, of one of these signal mediators in cells can cause activation of some signal cascades and formation of plant adaptive reactions.
