Stress-protective effect of phenylpropanoid complex on potato plants in vitro

The protective effect of jasmonic acid (JA) was evaluated under stress (100 mM NaCl) condition. The investigations were carried on potato plants (Solanum tuberosum L.) of the mid-season variety Lugovskoy. Plant-regenerants were grafted and cultured in test tubes on modified Murashige-Skoog agar medium in the absence (control) or in the presence of JA at concentrations of 0.001; 0.1 and 10 M under optimal growing conditions or with the addition of NaCl. After 28 days of cultivation, growth (length of stem and root, number of tiers and leaves, plant mass) and physiological (proline content and photosynthetic pigments, determination of the osmotic potential of cell exudate) of the plants were assessed. For the first time it has been shown that jasmonic acid (0.1 and 10 M) manifests a pronounced protective effect on potato plants under salt stress condition. The protective effect based on the partial removal of the salt negative effect on the main photosynthetic pigments and the maintenance of the osmotic status of cell contents during salinization.

The paper presents a study of the effect of chemically synthesized selenium nanocomposites (Se NCs) in natural polymer matrices arabinogalactan (AG) and starch (ST) on the viability of the potato ring rot pathogen Clavibacter sepedonicus (Cms), potato plants in vitro, and the soil bacterium Rhodococcus erythropolis. It was found that the studied Se NCs have an antibacterial effect against the phytopathogenic Cms, reducing its growth rate and ability to form biofilms. It was revealed that Se NC based on AG (Se/AG NC) stimulated the growth and development of potato plants in vitro as well as their root formation. At the same time, Se did not accumulate in potato tissues after the treatment of plants with Se NCs. The safety of the Se NCs was also confirmed by the absence of a negative effect on the growth and biofilm formation of the soil bacterium R. erythropolis. The obtained results indicate that Se NCs are promising environmentally safe agents for the protection and recovery of cultivated plants from phytopathogenic bacteria.

Vitro Model

SummaryThe effect of alfa-tocopherol on the cell-cell interactions at the vessel wall were studied, using an in vitro model of human umbilical vein endothelial cell cultures (HUEC). Immune triggered granulocytes (PMN) will adhere to and damage HUEC and platelets enhance this PMN mediated endothelial injury. When HUEC are cultured in the presence of vitamin E, 51Cr-leakage induced by complement stimulated PMN is significantly decreased and the enhanced cytotoxicity by platelets is completely abolished (p <0.001).The inhibition of PMN induced endothelial injury is directly correlated to a diminished adherence of PMN to vitamin E- cultured HUEC (p <0.001), which may be mediated by an increase of both basal and stimulated endogenous prostacyclin (PGI2) from alfa-tocopherol-treated HUEC (p <0.025). The vitamin E-effect is abolished by incubation of HUEC with the irreversible cyclo-oxygenase inhibitor, acetylsalicylic acid, but the addition of exogenous PGI2 could not reproduce the vitamin E-mediated effects.We conclude that vitamin E exerts a protective effect on immune triggered endothelial damage, partly by increasing the endogenous anti-oxidant potential, partly by modulating intrinsic endothelial prostaglandin production. The failure to reproduce vitamin E-protection by exogenously added PGI2 may suggest additional, not yet elucidated vitamin E-effects on endothelial metabolism.
