Abstract: A temperature control device is disclosed for a metering head of a paper machine. The control device includes a metering head fabrication, the fabrication defining an internal cavity. In use of the metering head, the cavity is filled with a liquid. A displacement tube is disposed within and extends along the cavity for optimizing a flow of the liquid along the boundaries of the cavity for permitting accurate temperature control of the metering head.

Abstract: The bacterial plant pathogen Pseudomonas syringae injects effector proteins into host cells via a type III protein secretion system to cause disease. The invention relates to the discovery that the type III effector HopU1 is a mono-ADP-ribosyltransferase (ADP-RT) and suppresses plant innate immunity. The HopU1 substrates in Arabidopsis thaliana extracts were RNA-binding proteins that possess RNA-recognition motifs (RRMs). A. thaliana knock-out lines defective in the glycine-rich RNA-binding protein AtGRP7, a HopU1 substrate, were more susceptible than wild type plants to P. syringae. The ADP-ribosylation of AtGRP7 by HopU1 required two arginines within the RRM. The invention provides novel methods for the modulation of the innate immune response of a plant to a biotic stress, including methods for enhancing or suppressing the innate immune response of the plant.

Abstract: A rod holder device is disclosed for holding a rod in a metering head of a size press. The rod holder device includes an elongate rod holder having a tending side and a back side and a front and a back face, the rod holder defining a cavity for the removable reception therein of the rod, the cavity extending between the sides of the rod holder. The rod holder defines an extension which extends between the sides of the rod holder. The extension has a proximal and a distal end and a first and a second surface, the distal end of the extension defining a plurality of spaced notches. A clamping plate has a first and a second extremity and a first and a second edge and a first a and a second face, the clamping plate being secured to the metering head. The clamping plate defines a plurality of spaced recesses.

Abstract: One aspect of the present invention relates to isolated nucleic acid molecules encoding avirulence proteins or polypeptides of Pseudomonas syringae pv. syringae DC 3000, or nucleic acid molecules which are complementary thereto. Expression vectors, host cells, and transgenic plants which include the DNA molecules of the present invention are also disclosed. Another aspect relates to the isolated proteins or polypeptides and compositions containing the same. The various nucleic acid molecules and proteins of the present invention can be used to impart disease resistance to a plant, make a plant hypersusceptible to colonization by nonpathogenic bacteria, modify a metabolic pathway in a cell, cause eukaryotic cell death and treat a cancerous condition, as well as inhibit programmed cell death.

Abstract: One aspect of the present invention relates to isolated nucleic acid molecules (i) encoding proteins or polypeptides of Pseudomonas CEL and EEL genomic regions, (ii) nucleic acid molecules which hybridize thereto under stringent conditions, or (iii) nucleic acid molecules that include a nucleotide sequence which is complementary to the nucleic acid molecules of (i) and (ii). Expression vectors, host cells, and transgenic plants which include the DNA molecules of the present invention are also disclosed. Another aspect relates to the isolated proteins or polypeptides and compositions containing the same. The nucleic acid molecules and proteins of the present invention can be used to imparting disease resistance to a plant, making a plant hypersusceptible to colonization by nonpathogenic bacteria, causing eukaryotic cell death, and treating cancerous conditions.
