Main subject

Functioning of redox systems in plant cells

Main topics

1) Contribution of apoplastic redox enzymes and nitrate reductase in the formation and metabolism of reactive oxygen and nitrogen species in plant roots and leaves under abiotic stress

2) Role of autophagy in the survival and death of plant cells

3) Role of sterols as raft-forming lipids and membrane activity in root cells

Main achievements for 2008-2012

  • Peroxidases responsible for detoxification and formation of reactive oxygen species in the apoplast of plant cells were identified and characterized. The bioinformatic analysis of the coding and non-coding regions in genes, the changes in gene expression and catalytic activity of stress-induced peroxidases enabled unraveling the physiological roles of these enzymes in plants under abiotic stress. It was found that the release of peroxidases from cells and the switch between peroxidative and oxidative regimes of extracellular peroxidases is a key early stress response of plant cells.

  • The oxidative burst in lichens, mosses and liverworts induced by desiccation / rehydration was demonstrated for the first time (in collaboration with Professor Richard Beckett, University of KwaZulu-Natal, South Africa). The main involved enzymes were found to be cell wall laccases, tyrosinases and peroxidases.

  • New mechanisms of redox regulation of seed germination and survival under the changing water supply have been suggested (in collaboration with Professor Ilse Kranner, University of Innsbruck, Austria and Professor Richard Beckett, University of KwaZulu-Natal, South Africa). It was found that the redox shifts in seeds are defined by the activity of peroxidases and the ratio of reduced/oxidized glutathione. These results provide a fundamental basis for the improvement of protocols of seed storage, in particular cryopreservation of recalcitrant seeds.

  • The features of autophagic degradation of oxidized macromolecules and damaged organelles in plant cells during the oxidative stress were characterized. The main stages of the formation of autophagosomes containing the fragments of cytoplasm and organelles were identified. The analysis of the expression profile of autophagic genes proves the importance of autophagic proteins in the formation of autophagosome and the degradation of organelles, in particular mitochondria.

  • The role of membrane sterols as structural macromolecules of plasma membrane and components of lipid microdomains (rafts) has been studied. Sterol saturation induces the alteration in membrane characteristics indicating a decrease in ion membrane permeability. In contrast, the binding of endogenous sterols by nystatin induces an increase in plasma membrane permeability and the changes in composition of glycoceramides, the raft-forming lipids. The physiological response triggered in plant cells by the changes in plasma membrane is accompanied with oxidative stress, formation of autophagosomes and a decline in cell viability.
  • An induction of oxidative and nitrosative stresses has been demonstrated to occur in leaves under the excess of nitrogen supply. The changes in biochemical characteristics, electron paramagnetic spectra and fluorescence detected by using specific dyes and traps suggest the involvement of nitrate reductase in the NO production in leaves.
