Abstract: Herbicide-resistant sunflower plants, isolated polynucleotides that encode herbicide-resistant and wild-type acetohydroxyacid synthase large subunit (AHASL) polypeptides, and the amino acid sequences of these polypeptides, are described. Expression cassettes and transformation vectors comprising the polynucleotides of the invention, as well as plants and host cells transformed with the polynucleotides, are described. Methods of using the polynucleotides to enhance the resistance of plants to herbicides, and methods for controlling weeds in the vicinity of herbicide-resistant plants are also described.

Abstract: The present invention relates to methods and devices for detecting one or more analytes or analyte products in a biological sample. This invention in particular relates to improved rapid tests such as “dipsticks” and “lateral flow” devices. The invention in particular relates to chromatographic device made of two active sides, in order to allow multiplex detections, quantitative or semi-quantitative detections, use of multiple sizes and kinds of particles or microspheres, use of different nitrocellulose porosities, use of different kinds of membranes. The devices described in this invention allow to detect or identify various biologicals or chemicals with one manipulation.
