20140123342 | Regulation of Stomatal Apertures by Apyrases and Extracellular Nucleotides - The role of extracellular nucleotides and apyrase enzymes in the guard cells that border stomata in regulating stomatal aperture and the plant's resistance to drought and pathogens is disclosed herein. Expression of apyrases APY1 and APY2, in guard cell protoplasts is strongly correlated with cell growth, cell secretory activity and with conditions that favor stomatal opening. Both short-term inhibition of ectoapyrase activity and long-term suppression of APY1 and APY2 transcript levels significantly disrupt normal stomatal behavior in light. Furthermore, two punnoceptor inhibitors in mammals, pyridoxalphosphate-6-azo-phenyl-2′,4′-disulphonic acid (PPADS) and Reactive Blue 2, block ATPS- and ADPβS-induced opening and closing, and also partially block the ability of abscisic acid (ABA) to induce stomatal closure, and light-induced stomatal opening. Treatment of epidermal peels with ATPyS induces increased levels of nitric oxide and reactive oxygen species, and genetically suppressing the synthesis of these agents blocks the effects of nucleotides on stomatal aperture. | 05-01-2014 |

20120240347 | APPARATUS AND METHOD FOR PRODUCING ROUND BRUSHES - An apparatus for producing round brushes, which have bristles twisted in between two portions of a folded wire. The apparatus has a bristle feeding device and a rotary gripper for twisting two portions of wire with bristles located therebetween, a deflecting device with two deflecting rollers spaced apart in the longitudinal direction of the wire. The rotary gripper is linearly displaceable transversely in relation to the longitudinal direction of the wire, for gripping the folded region of the wire that is formed by force being applied by an application element that is adjustable between the deflecting rollers transversely in relation to the longitudinal direction of the wire. A bristle feeding device, for feeding bristles to the bent-around portions of wire, is provided in the region of the deflecting rollers. In the region of the unfolded portions of wire there is provided a device for slowing the advancement of the wire. | 09-27-2012 |
