“…It was reported earlier that metals such as cadmium, copper, and chromium ions directly inhibit PSII electron transport at the water-splitting system of the RC (Küpper et al 2002;Popovic et al 2003;Dewez et al 2005;Ait Ali et al 2006). …”

“…Particularly, the change in rapid Chl a fluorescence induction has been shown to be dependent on water-splitting system functions at the PSII RC and to electron transport activity related to oxido-reduction states of respective electron acceptors quinone A (Q A ), quinone B (Q B ), and plastoquinone pool (Strasser and Strasser 1995;Dewez et al 2007). Ecotoxicological studies have shown that many photosynthetic-based fluorescence parameters can be sensitive biomarkers to both metallic and organic pollutants because these have different mechanisms of toxicity (Popovic et al 2003;Ralph et al 2007). …”

Toxicity of superparamagnetic iron oxide nanoparticles (SPION) was investigated in Lemna gibba plants exposed for 7 days to Fe3O4 (SPION-1), Co0.2Zn0.8Fe2O4 (SPION-2), or Co0.5Zn0.5Fe2O4 (SPION-3) at 0, 12.5, 25, 50, 100, 200 or 400 µg mL(-1). At < 400 µg mL(-1) of SPION exposure, toxicity was indicated by decrease of chlorophyll content, deterioration of photosystem II (PSII) functions, strong production of reactive oxygen species (ROS), and inhibition of growth rate based on fresh weight (52-59 %) or frond number (32-49 %). The performance index of PSII activity was the most sensitive biomarker of PSII functions and decreased by 83, 86, and 79 % for SPION-1, SPION-2, and SPION-3, respectively. According to the change of these biomarkers, the exposure of SPION suspensions to L. gibba caused several alterations to the entire plant cellular system, which may come from both the uptake of nanoparticles and metal ions in the soluble fraction. Our results, based on the change of several biomarkers, showed that these SPION have a complex toxic mode of action on the entire plant system and therefore affects its viability. Therefore, the plant model L. gibba was shown to be a sensitive bioindicator of SPION cellular toxicity and thus can be used in the development of a laboratory bioassay toxicity testing.

“…Based on the fact that a proportion of the absorbed light energy in PSII photochemistry cannot be used to drive electron transport and is dissipated via non-radiative energy as heat or chlorophyll fluorescence emission associated with the PSII complex [2,[11][12][13][14][15], information about changes in the efficiency of photosynthesis can be acquired by measuring the yield of Chl-α-fluorescence [2,16]. Chl-α-fluorescence is a physical signal defined as the radiative energy evolved from de-exciting Chl-α-molecules (λ = 690 nm for PSII, λ = 740 nm for PSI) [17] that has been used as a rapid, non-intrusive, and highly sensitive bioindicator of algal stress in response to different chemicals in recent years [2,18,19].…”

Algal studies remain necessary for risk assessment and their utility in ecotoxicology is the evaluation of lethal and sub-lethal toxic effects of potential toxicants on inhabitants of several ecosystems. Effects on algal photosynthetic apparatus caused by various chemical species have been extensively studied. The present chapter summarizes the published data concerning the toxicity of various organic and inorganic pollutants such as oils, pesticides, antifoulants and metals on photosynthesis of aquatic primary producers. Biochemical mode of action resulting in the disruption of photosynthesis depends on the chemical's nature and the characteristics of the exposed microorganism. Observed differences in response and sensitivity by different species to the same toxicant were attributed to several algal characteristics including photosynthetic capacity, pigment type, cellular lipid and protein content, and cell size. Single species bioassays either for one chemical alone or in mixture have been well reported and tolerance of both marine and freshwater water-column phytoplaktonic species has been examined. Adequate published information on multispecies tests (communities) in laboratory and field studies exists. However, risk assessment on photosynthesis of microbenthic periphyton is inadequate, though it is essential especially for hydrophobic organic molecules. Further studies are required to evaluate the adverse effects of metabolites on aquatic microalgae.

Ontogenetic approach to the assessment of plant resistance to prolonged stress using chlorophyll fluorescence induction method

2006

The review deals with objective reasons that limit the use of chlorophyll fluorescence induction kinetics (Chl FIK) method in plant ecology. Based on the ontogenetic approach (analysis and comparison of the dynamics of the Chl fluorescence ratio F p /F s and physiological characteristics of plant leaves in ontogeny) possible criteria for the estimation of general plant resistance of photosynthetic apparatus (PSA) to prolonged stress affects are proposed. One of these criteria is the presence or absence of a steady-state phase in the dynamics of Chl fluorescence ratio F p /F s (or R fd ) of plant leaves after they stop growing. We also propose to use the duration of the steady-state phase and variability of Chl fluorescence ratios R fd and F p /F s in this period for quantitative assessment of plant PSA resistance to prolonged stress during plant leaf ontogeny.Additional key words: leaf age; photosystems 1 and 2; radiation colour; specific leaf growth rate.
