“…Moreover, ALAD activity varied negatively with temperature and AChE with salinity and dissolved oxygen, and this has already been pointed out by others authors in different bivalve species (Dellali et al, 2001;Pfeifer et al, 2005). It is also known that AChE is directly affected by temperature (Dellali et al, 2001;Leiniö and Lehtonen, 2005;Pfeifer et al, 2005). In the present work, no significant correlation was found between this biomarker and temperature (p > 0.05), but the lowest mean AChE activity was at site 4, where the mean temperature was also lowest (Table 2).…”

“…Metals, among other compounds, may also decrease AChE activity, and in this study, this biomarker had minimum values in site 2, where Cd, Cu and Pb concentrations (and % of 4 rings PAHs) were highest. Moreover, ALAD activity varied negatively with temperature and AChE with salinity and dissolved oxygen, and this has already been pointed out by others authors in different bivalve species (Dellali et al, 2001;Pfeifer et al, 2005).

“…The yield gap is mainly due to erratic rainfalls, water scarcity in rainfed areas and high temperature. Pfeiffer et al (2005) reported that drought affects the 50% of wheat area worldwide. Under such moisture stress conditions development of rapid, effective screening method is a major challenge for plant breeders (Khan et al, 2013;Mahmood et al, 2013;Subhani et al, 2012).…”

Estimation of genetic components for plant growth and physiological traits of wheat (Triticum aestivum L) under normal and stress conditions

This study was conducted to investigate the genetic variability of plant growth and physiological characters in thirty wheat genotypes under normal and drought stress conditions. Selection of important plant growth and physiological traits are essential component for wheat yield improvement. For this purpose, an experiment was conducted in the glasshouse during 2012-13 to estimate the extent of genetic components viz., genetic variance, coefficient of variability and broad sense heritability for plant growth and physiological traits under normal and drought stress conditions. Higher genetic variance was observed between the genotypes for the cell membrane stability, excised leaf water loss, relative water content, proline, sugar and glycine betain under both conditions. This suggested that these indices can be used as direct selection criteria for wheat improvement. While excised leaf water loss and fresh root weight revealed the least variability for GCV and PCV correspond to high heritability under stress condition. Hence, these traits can be used as indirect selection criteria under stress condition.

“…A more generalized version which would also accommodate whole animal studies would include 'measurements on whole animals' and 'indicate in physiological, behavioural or energetic terms' (Ross et al 2002;Magni et al 2005). There are molecular, cellular and whole animal biomarkers-some specific to pollutants (Table 2), others which change in response to both pollutants and natural stressors (Pfeifer et al 2005). Such diagnostic and prognostic early warning tests offer the potential of specificity, sensitivity and application to a wider range of organisms ( Fig.…”

This paper presents an overview of the significance of the use of molecular biomarkers as diagnostic and prognostic tools for marine pollution monitoring. In order to assess the impact of highly persistent pollutants such as polychlorinated biphenyls (PCB), polychlorinated dibenzo-dioxins (PCDD), polychlorinated dibenzo-furans (PCDF), polynuclear aromatic hydrocarbons (PAH), tributyltin (TBT) and other toxic metals on the marine ecosystem a suite of biomarkers are being extensively used worldwide. Among the various types of biomarkers, the following have received special attention: cytochrome P4501A induction, DNA integrity, acetylcholinesterase activity and metallothionein induction. These biomarkers are being used to evaluate exposure of various species of sentinel marine organisms (e.g. mussels, clams, oysters, snails, fishes, etc.) to and the effect of various contaminants (organic xenobiotics and metals) using different molecular approaches [biochemical assays, enzyme linked immuno-sorbent assays (ELISA), spectrophotometric, fluorometric measurement, differential pulsed polarography, liquid chromatography, atomic absorption spectrometry]. The induction of the biotransformation enzyme, cytochrome P4501A in fishes (Callionymus lyra, Limanda limanda, Serranus sp., Mullus barbatus) and mussels (Dreissena polymorpha) by various xenobiotic contaminants such as PCBs, PAHs, PCDs is used as a biomarker of exposure to such organic pollutants. The induction of cytochrome P4501A is involved in chemical carcinogenesis through catalysis of the covalent bonding of organic contaminants to a DNA strand leading to formation of DNA adduct. Measurement of the induction of cytochrome P4501A in terms of EROD (7-ethoxy resorufin O-deethylase) activity is successfully used as a potential biomarker of exposure to xenobiotic contaminants in marine pollution monitoring. In order to assess the impact of neurotoxic compounds on marine environment the evaluation of acetylcholinesterase activity in marine organisms is used as a biomarker of exposure to neurotoxic agents such as organophosphorus, carbamate pesticides etc. Metallothioneins (MTs) are induced by toxic metals such as Cd, Hg, and Cu by chelation through cysteine residues and are used in both vertebrates and invertebrates as a biomarker of metal exposure. The measurement of the levels of DNA integrity in marine organisms such as Sea stars (Asterias rubens) from the North Sea and the marine snails (Planaxis sulcatus) from the Arabian Sea along the Goa coast exposed to environmental xenobiotic contaminants clearly indicated the extent and the nature of pollution at the sampling sites along coastal environment.
