Sažetak
Hydrogen sulphide (H2S) is known to be produced by both animal and plant tissues suggesting that this compound may be involved in cell signal transduction. There is a growing body of evidence to suggest that the presence of this gasotransmitter may modulate oxidative stress metabolism in cells. In collaboration between English and Croatian Universities, it was found that pepper plants pre-treated with H2S donors, such as NaSH and GYY4137, and exposed to the salt stress, showed significant differences in lipid peroxidation levels, hydrogen peroxide and proline concentrations. Cucumber seeds pre- treated with H2S donors and germinated in NaCl solution, showed a significant influence of H2S treatments on the same parameters as in pepper. The results suggested that H2S may have a regulatory role in stressed plants and may affect the accumulation of protective metabolites such as proline. Crucial tools in this kind of research are H2S-releasing compounds with different chemical properties, such as cell permeability or H2S releasing rate, along with in vivo methods of detection of H2S using highly specific fluorescence probes. As well as for purely academic reasons these compounds may have practical applications in agriculture through the fostering of plant environmental stress tolerance.
