The sensitive genotypes

showed greater enhancement of phytochelatins than that of tolerant genotypes. Hence, the possibility of phytochelatins in improving copper tolerance in the test plant is also excluded. Interestingly, the order of proline accumulation in the chickpea genotypes (RSG 888 > CSG 144 > CSG 104 > RSG 44) was exactly similar to the order of copper tolerance. Based on hyperaccumulation of proline in tolerant genotype (RSG 44) and the reduction and improvement of lipid peroxidation buy OICR-9429 and tolerance index, respectively, by proline pretreatment, we conclude that hyperaccumulation of proline improves the copper tolerance in chickpea.”
“Reelin (RELN) is a large glycoprotein that plays critical roles during and after neuronal development. In a previous study utilizing developing zebrafish, the RELN ortholog was in a subset of genes associated selleck kinase inhibitor with neuronal function that was altered following exposure to 100 ppb Pb at 72 h post-fertilization (hpf). Although RELN is associated with neurodevelopment and neurological diseases, it represents a previously

uncharacterized target for developmental Pb neurotoxicity. To further investigate Pb-induced expression decrease of RELN, a more detailed analysis was done using in situ hybridization and quantitative PCR (qPCR) on developing zebrafish at multiple developmental time points and at different exposure concentrations. Time points included in the analysis were 24, 36, 48, 60, 72 and 96 hpf. The four exposure conditions Cytidine deaminase tested were 10,50 or 100 ppb Pb as well as a control. In situ hybridization demonstrated concentrated expression of the gene in the telencephalon and in midbrain, hindbrain and spinal cord. Expression was less spatially restricted early in development but became isolated to specific cell populations in the central nervous system by 48 hpf. The telencephalon demonstrated a high degree of expression throughout development. Pb exposure did not affect the observed location of expression at any of the time points tested. However, qPCR analysis demonstrated that rein expression statistically

decreased in embryos exposed to the highest concentration compared to controls at 60 hpf. No changes in brain morphology as assessed by measuring brain length and no significant increase in the number of apoptotic cells in the brain were observed at the highest exposure concentration. These data demonstrate that a decrease in rein expression occurs following Pb exposure at a concentration below one that results in changes in brain length or in the number of apoptotic cells in the zebrafish model system during a short window and is likely linked to concurrent developmental processes.
