Abstract: The genes encoding ryanodine receptor homologs have been characterized from multiple insect families including lepidopteran tobacco budworm (Heliothis virescens), homopteran green peach aphid (Myzus persicae), corn plant hopper (Peregrinus maidis), cotton melon aphid (Aphis gossypii) and fruitfly (Drosophila melanogaster). The full-length genes have been isolated, cloned and amplified in bacterial cells. Expression in insect cells shows that the recombinant protein folds into a functional calcium release channel.

Abstract: The invention relates to the isolation and modification of nucleic acid sequences encoding p-hydroxyphenylpyruvate dioxygenase enzyme from plants. These nucleic acid sequences were used to establish methods of identification of new herbicidal compounds that inhibit the activity of this enzyme, and to prepare new crop plants that are tolerant to the herbicidal action of inhibitors this enzyme. Chimeric genes comprising nucleic acid fragments containing all or part of the nucleic acid sequences encoding p-hydroxyphenylpyruvate dioxygenase may be used to produce active plant p-hydroxyphenylpyruvate dioxygenase enzyme in microorganisms, and to cause the production of modified forms of the enzyme in plants that may render such plants tolerant to inhibitors of the enzyme.

Abstract: A light collector for use with a photodetector that provides uniform photodetector output response over a polar angular range regardless of the polar angle of incidence of light upon the collector is disclosed. The light collector comprises a generally spheroidally-shaped light direction changer having a light diffusing surface, and a generally spheroidally-shaped polar attenuator. The geometric center of the photosensitive surface of the photodetector is adjacent to the vertex of the generally spheroidally-shaped light direction changer.

Abstract: Methods and apparati for screening compounds for agricultural activity has now been developed which employ e.g., intact plants grown in microtiter plates on very small amounts of plant growth media containing a test compound. In comparison to the standard greenhouse screen, the microscreen requires vastly less space, labor, and test compound. However, unlike in vitro screens, responses of intact plants are assayed. Using the microscreen, high-throughput screening of test compounds can be accomplished using whole plant responses as the assay.
