“…is often used in research studies as a symptom of stress (e.g. Mateos-Naranjo et al 2008, Li et al 2010. Although chlorophyll concentrations measured in the affected zones in this study were reduced by 47% in snail sites, it was surprising how little the chlorophyll concentrations were influenced by the other disturbance types.…”

“…These have either reported the effects of metal toxicity on Spartina alterniflora in greenhouse studies (Mendelssohn et al 2001, Mateos-Naranjo et al 2008 or have examined metal accumulation in the field at polluted sites (Cambrollé et al 2011, Salla et al 2011. Across these studies, S. alterniflora was highly tolerant of soil metal contamination, able to hyperaccumulate metals, and capable of phytoremediation (Salla et al 2011).…”

We evaluated 2 potential indicators of stress, viz. the ratio of dimethylsulfoxide to dimethylsulfoniopropionate (DMSO:DMSP) and foliar metals, in Spartina alterniflora collected from areas affected by 4 different disturbances (sudden marsh dieback, horse grazing, increased snail densities, wrack deposition) across 20 marshes in Georgia, USA. The DMSO:DMSP ratio was a stronger and more consistent indicator of stress than either DMSP or DMSO concentrations alone, with significantly higher ratios occurring in leaves and stems collected from affected compared to healthy areas in all 4 disturbance types. Foliar metal concentrations also differed in affected compared to healthy areas. Of 20 metals evaluated, concentrations of 19 were increased in leaves collected from edge and affected areas. Multidimensional scaling using the entire suite of metals showed separation between plants from affected and healthy areas, but no difference among disturbance types. In contrast, chlorophyll a concentrations were not significantly different between affected and healthy areas, and did not correlate with variation in either of the 2 indicators. These results suggest that the DMSO:DMSP ratio and foliar metal suite are sensitive indicators of sublethal stress in Spartina, capable of identifying stress before there are visible signs such as chlorophyll loss. The fact that both indicators were consistent across a variety of disturbance types suggests that they may be primarily responsive to general oxidative stress and thus, broadly useful tools for evaluating the health of salt marsh habitat in the field. Spartina alterniflora salt marsh near St. Simons Island, GA, with a dieback area along the edge of the tidal creek.

“…In addition to the uptake process, the inhibitory effects of Zn on the translocation of Cu in leaves (old and young) grown at low Cu concentrations (T1 and T2) were found. However, the content of the studied elements was higher in the roots of sweet potato plants, and this result suggested that these organs developed sequestration and compartmentalization mechanisms (mainly for Cu) as the availability of micronutrients increased, thus improving tolerance to heavy metals (Mateos-Naranjo et al 2008).…”

“…However, in T4, the inhibition of SOD activity by the additive effect of Cu could be a consequence of poor gene expression or the degradation, denaturation, and/or inhibition or inactivation of those proteins (Cavalcanti et al 2007). Another hypothesis is that the activity of this enzyme could have been reduced by both the compartmentalization and sequestration of micronutrients (e.g., Zn, Cu, and Fe) in the root tissues, thus promoting reduced translocation to shoots and decreased ROS formation (Mateos-Naranjo et al 2008).…”

“…In this case, the alterations in chlorophyll production occurred as an effect of decrease in availability of ions such as Fe and Mn or peroxidation of chloroplast membranes resulting from heavy metal induced oxidative stress (Dhir et al 2011). Disturbances in photosynthesis were also noticed in many others plants from different families (Küp-per et al 2002, Liu et al 2004, Mateos-Naranjo et al 2008, Domínguez et al 2011. Thus, in order to better understanding the influence of heavy metals on G. fastigiata photosynthetic apparatus efficiency, more parameters should be examined.…”

An excessive amount of heavy metals negatively affects the environment, causing degradation of large areas throughout the world. Therefore, the effective and inexpensive techniques focused on either removal of those substances or their long-term stabilization in situ need to be improved. We currently propose to use a calamine ecotype of Gypsophila fastigiata (Caryophyllaceae) for biological reclamation of wastes accumulated after Zn-Pb ores enrichment. Plants were cultivated in (1) untreated waste material (control), (2) wastes enriched with mineral fertilizers, and (3) wastes enriched with sewage sludge. Photosynthetic pigments content and electrolyte leakage outside plasma membrane were tested periodically in representative samples. In untreated waste material growth gradually deteriorated during the season. The content of chlorophyll a in leaves taken from control plants decreased more than threefold from 0.51 mg/g f.m. at the beginning to 0.14 mg/g f.m. at the end of the growing season, whereas in treatment with sewage sludge the reduced seasonal variations in photosynthetic pigments content was ascertained (0.78 mg/g f.m. for chl a and 0.20 mg/g f.m. for chl b, both in the spring and autumn) what positively influenced the plant growth. The results indicate that tested G. fastigiata genotype might be used in an assisted revegetation project.
