“…The presence of free sulfide has been noted in several natural environments: rice paddy soils, flooded soils, marine sediments, salt marshes, and generally in anoxic environments (1,4,6,7). Sulfide is produced in those anoxic environments where there is a supply of sulfate ions and organic matter adequate for the sulfate-reducing bacteria (e.g.…”

“…Industrial sources of H2S also contribute to the pollution of waters, soils, and atmosphere (6). Sulfide levels in those environments are variable, but levels higher than 40 gM frequently have been detected (6,7). These levels can inhibit, at least partially, Cyt c oxidase of the plant tissues exposed to sulfide (see Fig.…”

“…However, cyanide has been the inhibitor of Cyt c oxidase most frequently used to estimate the so-called "cyanide-resistant respiration" (8,9). Sulfide has been little used in works on plant respiration, mainly in some ecophysiological studies on the effects of sulfide as an environmental pollutant (1,4,6,7). The results suggest that usually there is little inhibition of respiration by sulfide, that is, a considerable "sulfide-resistant respiration" exists in plants.…”

The rate of dark 02 uptake of Elodea canadensis leaves was titrated with either cyanide or sulfide in the presence and in the absence of 5 millimolar salicylhydroxamic acid (SHAM), an inhibitor of the altemative oxidase. The inhibition of 02 uptake by SHAM alone was very small (3-6%), suggesting that actual respiration mainly occurred through the cytochrome pathway. 02 uptake was slightly stimulated by cyanide at concentrations of 50 micromolar or higher, but in the presence of SHAM respiration was strongly suppressed. The effects of sulfide on 02 uptake were similar to those of cyanide, except that the percent stimulation of 02 uptake by sulfide alone was somewhat higher than that of cyanide. However, the estimates of the capacity of the altemative pathway were similar with both inhibitors. Another difference is that maximal inhibition of respiration in the presence of SHAM was observed with lower concentrations of sulfide (50 micromolar) than cyanide (250 micromolar). The results suggest that sulfide can be used as a suitable inhibitor of cytochrome c oxidase in studies with intact plant tissues, and that sulfide does not apparently inhibit the altemative oxidase.Cyanide and sulfide are noncompetitive inhibitors of Cyt c oxidase and their comparative effects have been widely studied at the enzyme level (5, 10, 12). However, cyanide has been the inhibitor of Cyt c oxidase most frequently used to estimate the so-called "cyanide-resistant respiration" (8, 9). Sulfide has been little used in works on plant respiration, mainly in some ecophysiological studies on the effects of sulfide as an environmental pollutant (1, 4, 6, 7). The results suggest that usually there is little inhibition of respiration by sulfide, that is, a considerable "sulfide-resistant respiration" exists in plants. However, as far as we know, there have been no attempts to relate the use of sulfide with the expression of the different mitochondrial electron transport pathways in intact plant tissue, and this will be the main objective of this communication.The results obtained in the present work suggested that the effects of sulfide and cyanide on respiration of Elodea canadensis leaves are comparable, that is, both compounds inhibited the Cyt pathway, and elicited the expression of the 1249 nonphosphorylating alternative pathway. The higher activity of the alternative pathway in the presence of sulfide should be taken into account in the interpretation ofecophysiological studies on sulfide pollution in relation to respiration. MATERIAL AND METHODS Plant MaterialPlants of Elodea canadensis Michx were bought from an aquarium shop and were further grown for a few days in a cabinet under constant conditions: 20C (day and night), and a quantum flux density (400-700 nm) of 100 to 200 1AE/m2. s, supplied by Sylvania cool-white VHO (215 W) fluorescent tubes for 13 h/d. Plants were placed in an aerated nutrient solution containing KNO3, 1 mM; Ca(NO3)2, 1 mM; MgSO4, 0.375 mM; NaH2PO4, 0.33 mM; EDTA FeNa, 13.5 ,uM. Measurement of Respiration02 u...

“…The positive response of Salicornia europaea to sulfide as compared with other tested halophyte species, including Aster tripolium, Halimione portulacoides, Suaeda maritima, and Puccinellia maritima, was attributed to its habitat (Ingold and Havill, 1984).…”

“…Thus, it has been reported that increasing the sulfate concentration in the growth medium of 2% seawater-grown marsh cordgrass Spartina alterniflora resulted in a positive growth response, but no such growth response was seen in Spartina cynosuroides and in Spartina anglica grown with 0 mM to 1.6 mM sulfate supply (Stribling, 1997;Mulholland and Otte, 2000). Interestingly, Salicornia europaea has been determined to be extremely tolerant to sulfide ion accumulation (Ingold and Havill, 1984;Havill et al, 1985), although the tolerance mechanism is not understood. In contrast, Martin and Maricle (2015) examined 17 estuarine species, reporting that those with higher levels of cytochrome c oxidase activity were more sulfide-tolerant than those with lower levels.…”

Sulfide Generated by Sulfate Reduction is a Primary Controller of the Occurrence of Wild Rice (Zizania palustris) in Shallow Aquatic Ecosystems

Field observations suggest that surface water sulfate concentrations control the distribution of wild rice, an aquatic grass (Zizania palustris). However, hydroponic studies show that sulfate is not toxic to wild rice at even unrealistically high concentrations. To determine how sulfate might directly or indirectly affect wild rice, potential wild rice habitat was characterized for 64 chemical and physical variables in over 100 sites spanning a relatively steep climatic and geological gradient in Minnesota. Habitat suitability was assessed by comparing the occurrence of wild rice with the field variables, through binary logistic regression. This analysis demonstrated that sulfide in sediment pore water, generated by the microbial reduction of sulfate that diffuses or advects into the sediment, is the primary control of wild rice occurrence. Water temperature and water transparency independently control the suitability of habitat for wild rice. In addition to generating phytotoxic sulfide, sulfate reduction also supports anaerobic decomposition of organic matter, releasing nutrients that can compound the harm of direct sulfide toxicity. These results are important because they show that increases in sulfate loading to surface water can have multiple negative consequences for ecosystems, even though sulfate itself is relatively benign.
