[Role of phospholipase D in metabolism reactions of transgenic tobacco cax1 cells under salinity stress].

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