Abstract: Methods of increasing the resistance of plants, in particular soybeans, to nematodes, in particular soybean cyst nematodes, are provided herein. The methods include increasing the expression of Glyma18g02580, Glyma18g02590 and/or Glyma18g2610 in cells of a plant and in particular in root cells of a plant to increase the resistance of the plant and plant cells to nematodes. The methods include increasing the expression using constitutive promoters or by increasing the copy number of the polynucleotides. Constructs for expressing these polypeptides, transgenic cells, transgenic plants and methods of generating the same are also provided. Methods of screening plant cells for resistance or susceptibility to nematodes are also provided.

Abstract: An animal barrier device comprising one or more rotating bodies and fixture structures, in which in use the fixture structures, rotatably support the one or more rotating bodies on a construction with which the animal barrier is used, in which each rotating body is an elongate body which rotates in use about a longitudinal axis, and in which the longitudinal axis is located at any point on a line between a center of the rotating body and a point below the rotating body.

Abstract: An autonomous genosensor apparatus and methods for use are provided for the field detection and analysis of ambient chemical, biochemical, biologic, biogenetic, and radiologic materials under field conditions in fluid or gaseous environments, such as marine or aquatic environments or industrial processes. Autonomous genosensors provide integral, self contained units which automatically extract environmental samples, prepare those samples for analytical studies, analyze those samples using studies such as DNA or biomarker analysis, and store or transmit the data produced to a remote computer or computer network. Autonomous genosensors may be used as freestanding units, or may be networked and controlled through a remote computer network.

Abstract: A gas turbine engine nozzle segment and process for producing such a nozzle segment to exhibit improved durability and aerodynamic performance. The process produces a nozzle segment having at least one vane between and interconnecting a pair of platforms. The nozzle segment is cast from a gamma prime-strengthened nickel-base superalloy, on whose surface is thermal sprayed an environmental coating formed of a MCrAlX-type coating material. The surface of the environmental coating is then worked to cause the coating to have a surface finish of less than 2.0 micrometers Ra. Cooling holes are then drilled in the nozzle segment, after which an oxidation-resistant coating is applied on the smoothed surface of the nozzle segment so as to maintain an outermost surface on the nozzle segment having surface finish of less than 2.0 micrometers Ra.

Abstract: The present invention provides core technologies necessary for a portable, low cost, thermal-regulating LED-based handheld fluorometer. The regulated fluorometer is based on a low thermal mass infrared heater, and an orthogonal geometry LED based filter fluorometer. Power is supplied through an external power supply and data is collected in real-time through standard serial interfaces of personal computers or personal digital assistants. Thermal regulation is automatically maintained using temperature sensor feedback control. Optical excitation relies on LED light source(s) and optical detection is through an adjustable integrating photodetector. Such a handheld system can allow applications requiring temperature sensitive photometric measurements for real time analyte detection to be performed in the field.

Abstract: Methods are provided for producing an expression vector. In the subject methods, donor and acceptor vectors are combined in the presence of a recombinase to produce an expression vector that includes a first and second recombinase recognition site oriented in the same direction, wherein the first and second recombination sites are able to recombine with each other. In the subject methods, one of the donor and acceptor vectors includes a single recombinase recognition site while the other includes two recombinase recognition sites. Also provided are compositions for use in practicing the subject methods, including the donor and acceptor vectors themselves, as well as systems and kits that include the same. The subject invention finds use in a variety of different applications, including the transfer or cloning of a nucleic acid of interest from a first vector into one or more expression vectors, etc.

Abstract: A method for applying a chromium containing coating to an underlying metal substrate where the metal substrate has an overlaying platinum-containing layer, as well as a corrosion resistant coated article thereof. A chromium-containing layer is deposited on the platinum-containing layer with an aluminide diffusion layer being deposited on the chromium-containing layer, the aluminide diffusion layer having an inner diffusion layer adjacent the chromium-containing layer and an outer additive layer adjacent to the inner diffusion layer. The chromium-containing layer is deposited by a deposition technique that permits chromium in the chromium-containing layer to more readily diffuse into a subsequently deposited aluminde diffusion coating layer. The chromium-containing and aluminide diffusion layers are then treated to cause chromium from the chromium-containing layer to diffuse into the outer additive layer in an amount of at least about 8%. The resulting coated article is resistant to corrosion.

Abstract: Methods are provided for producing a vector that includes at least one splicable intron. In the subject methods, intron containing vectors are produced from donor and acceptor vectors that each include a site specific recombinase site, where the subject donor and acceptor vectors further include splice donor and acceptor sites that, upon site specific recombination of the donor and acceptor vectors, define an intron in the product vector of the recombination step. Also provided are compositions for use in practicing the subject methods, including the donor and acceptor vectors themselves, as well as systems and kits that include the same. The subject invention finds use in a variety of different applications, including the production of expression vectors that encode C-terminal tagged fusion proteins, the production of expression vectors that encode pure protein and not a fusion thereof, and the like.

Abstract: siRNA encoding constructs and methods for using the same are provided. The subject constructs are characterized by including a siRNA coding domain flanked by opposing promoters. In using the subject constructs, sense and antisense strands of the desired siRNA product encoded by the coding domain are transcribed under the direction of the two opposing promoters flanking the coding domain. The transcribed sense and antisense strands are then annealed to each other to produce the desired siRNA double-stranded molecule. The subject constructs and methods find use in a variety of applications, including applications where the specific reduction or silencing of a gene is desired. Also provided are systems and kits for use in practicing the subject invention.
