Sažetak:
Besides already well known actions in animal organisms and described effects on stomata closing in plants, nitric oxide (NO) influences on seed dormancy, flower development, root gravitropism, gene expression, plant defence reactions in pathogen attack, photomorphogenesis, Zn excess tolerance, antioxidative protection from UV-B radiation etc. Similar issues are now being addressed with regards to hydrogen sulphide (H2S). A body of literature exists which shows that H2S can affect the growth of plants, but more recent work has been published that suggests that H2S is a more fundamental molecule which is produced by plants and used to control different plant functions. Known as a signalling molecule in both animal and human tissues, H2S participates in signalling crosstalk in plants during stress, helping them to overcome unfavourable growth conditions through an increase of stress enzymes activity, preventing membranes destruction and enhancing accumulation of osmoprotective metabolites such as proline. It is probably the interaction of H2S with metabolism of other reactive species which accounts for many of the effects seen. Furthermore, we showed that H2S mediates stomatal opening using A. thaliana L. and Capsicum annuum L. plants as a model systems. Using the specific NO fluorescence probe it was shown that H2S reduced NO accumulation to a large extent, which may account for the effects of H2S seen. Further research should reveal if the interactions of H2S and NO signalling pathways may regulate some other metabolic responses in plants, as well, with possible influence of H2S on plant productivity and quality.
