Abstract: The present invention discloses gene targets, constructs and methods for the genetic control of plant disease caused by nematodes of the genus Pratylenchus (root lesion nematodes). The present invention relates to achieving a plant protective effect through the identification of target coding sequences and the use of recombinant DNA technologies for post-transcriptionally repressing or inhibiting expression of the target coding sequences in the cells of plant-parasitic nematodes. The disclosed gene targets are conserved and expected to be essential and sensitive to RNAi perturbation in different Pratylenchus species, facilitating genus-wide targeting by RNA interference.

Abstract: A method and device for generating a collimated laser beam which is circular in cross-section, non-astigmatic, diffraction-limited and has a gaussian energy distribution are disclosed. The device comprises a single mode optical waveguide having an input end and an output end, a laser diode optically coupled to the input end of the optical waveguide for producing at the output end thereof a laser beam which is circular in cross-section, non-astigmatic and diffraction-limited and has a gaussian energy distribution, and a collimating lens for collimating the laser beam. The collimating lens is disposed in spaced relationship to the output end of the optical waveguide such that the output end is positioned at the focal point of the collimating lens.

Abstract: A laser scanning system for scanning a laser beam across a material, comprises a laser source for generating a laser beam travelling along a first optical path and a beam reflector in the path of the laser beam. The beam reflector is rotatable about a rotation axis and includes a single mirror facet which extends in a plane oriented at an angle of 45.degree. relative to the rotation axis and has a center of rotation lying on the rotation axis, for reflecting the laser beam into a scanning beam moving at a substantially constant angular velocity. A scan lens is disposed in the path of the scanning beam for focusing the scanning beam onto the material. The laser scanning system of the invention further includes a support for supporting the laser source, beam reflector and scan lens relative to one another. The support has a unitary body formed with a first bore extending through the body.
