Role of phospholipase D in metabolic reactions of transgenic tobacco cax1 cells under the influence of salt stress

This work was aimed at investigating the primary reactions of plant cell metabolism in response to salt stress. It was found that the phospholipase D regulatory enzyme is activated in wild-type and transgenic cax1 tobacco plants during the early stages of the influence of salt stress. We have shown that a disturbance in the intracellular homeostasis of calcium ions and oppression of phospholipase D activity decrease the resistance of tobacco plants under the influence of salinity and also indicate the involvement of such systems in signaling during stress adaptation of plants.
