Ectopic expression of the GmERF3 gene in transgenic tobacco plants induced the expression of some PR genes and enhanced resistance against OTX015 molecular weight infection by Ralstonia solanacearum, Alternaria alternata, and tobacco mosaic virus (TMV), and gave tolerance to high salinity and dehydration stresses. Furthermore, overexpression of GmERF3 in transgenic tobacco led to higher levels of free proline and soluble carbohydrates compared to wild-type plants under drought conditions. The overall results suggested that GmERF3 as an AP2/ERF transcription factor
may play dual roles in response to biotic and abiotic stresses in plants.”
“We report the thermal chemical vapor deposition of vertically-aligned multiwalled PRN1371 purchase carbon nanotube forests directly onto electrically conductive cobalt disilicide (CoSi(2)) support using Fe as catalyst. We find that CoSi(2) support layer is able to prevent the agglomeration of the catalyst and favor vertically-aligned growth better than a SiO(2) support and comparable to an Al(2)O(3) support. This is an unusual behavior for a conductive support. This is because CoSi(2) has a lower surface energy than most
metals or metallic compounds. This has great benefits in the application of CoSi(2) as support for CNTs as horizontal and vertical interconnects. (C) 2010 American Institute of Physics. [doi:10.1063/1.3456168]“
“The annihilation of the radicals in irradiated 2-hydroxyethyl methacrylate copolymer was analyzed by the use of electron paramagnetic resonance (EPR) spectroscopy. The EPR spectra were deconvoluted into three radicals: a quartet (Ra), a triplet (Rb), and a broad singlet (Rc). Radical Ra was attributed to coupling with a methyl radical and/or a doublet or triplet with about the same hyperfine coupling due to a methylene radical. Radical Rb was due to a methylene radical produced by main-chain scission. Radical Rc was attributed to various free radicals without coupling to protons. By comparing the EPR spectra of radicals Ra, Rb, and Rc with the
spectrum of a 2,2-diphenyl-1-picrylhydrazyl (DPPH) standard with a known spin number, we calculated the spin numbers of the radicals, which decreased with time in the temperature check details range 25-45 degrees C, regardless of the irradiation dose. The annealing of Ra and Rb and the armealing of Rc at longer times followed second-order kinetics; these were different from the kinetics for the color formation and defect-controlled hardening of polymers.

“Composite plants consisting of a wild-type shoot and a transgenic root are frequently used for functional genomics in legume research. Although transformation of roots using Agrobacterium rhizogenes leads to morphologically normal roots, the question arises as to whether such roots interact with arbuscular mycorrhizal (AM) fungi in the same way as wild-type roots.
