A putative nuclear targeting domain was identified in the translated AmDHN1a ORF and stably transformed AmDHN1a-GFP was found to show nucleo-cytoplasmic localization in tobacco guard cells. As observed for maize Rab17, the phosphorylation

of AmDHN1 a may contribute to its nuclear localization. (C) 2009 Elsevier Masson SAS. All rights reserved.”
“We investigate the morphological instability of ferromagnetic planar thin films using linear perturbation theory. We find that, for a uniformly magnetized ferromagnetic planar film with a nonzero component of the magnetization along the normal to the planar film, the planar surface is unstable with respect to perturbations having a wave number smaller than a critical value. In addition, the critical wave number changes with the direction of the surface perturbations,

with the perturbations BMS202 chemical structure perpendicular to the in-plane component of the magnetization having the largest critical PD0332991 research buy wave number. Such anisotropy could be important in controlling the evolution of the morphology of the film and nanoscale-island formation. (C) 2009 American Institute of Physics. [doi:10.1063/1.3239989]“
“The objective of this study was to compare the antioxidant activities of lyophilized olive leaf water extracts (OLWExtracts) from 21 different olive tree cultivars. The highest total phenolic content (102.69 +/- 1.63 mu g GAE/mg extract) was found in cultivar ‘Esek Zeytini’ and the lowest content (78.52 +/- 2.18 mu g GAE/mg extract) was in ‘Uslu’. The highest total flavonoid

content (12.47 +/- 0.12 mu g QE/mg extract) obtained from ‘Frantoio’. According to EC50 values, ‘Domat’ have the highest DPPH scavenging activity (EC50 =59 mu g/mL), reducing power (EC50 =180 mu g/mL), and superoxide radical scavenging capacity (EC50=44 mu g/mL). While, ‘Ascolana’ showed the highest metal chelating capacity (EC50=163 mu g/mL), ‘Memecik’ showed the highest hydrogen peroxide (H2O2) scavenging capacity. Research results exhibited that OLWExtracts are comparable to synthetic antioxidants. The correlation study showed that while total phenolic content correlated with DPPH scavenging activity and reducing power (p < 0.01), total flavonoid content 此网站 correlated with metal chelating and superoxide radical scavenging capacity (p < 0.05).”
“Soil flooding is a seasonal factor that negatively affects plant performance and crop yields. In order to investigate the effects of spermidine (Spd) and spermine (Spm) on the waterlogging stress, it was checked that the content of relative water content (RWC), proline, chlorophyll and malondialdehyde (MDA), net photosynthesis, the rate of hydrogen peroxide (H(2)O(2)) and superoxide radicals (O(2)(-)) generation and the antioxidant enzyme activities of superoxide dismutase (SOD) (EC 1.15.1.1), catalase (CAT) (EC 1.11.1.6), ascorbate peroxidase (APX) (EC 1.11.1.11) and glutathione reductase (GR) (EC 1.6.4.2) in Welsh onion (Allium fistulosum L) plants.
