Abstract: Through function complementation of E. coli auxotrophs, the ultimate and pentultimate enzymes of the spinach riboflavin biosynthetic pathway have been cloned, namely, lumazine synthase (LS) and riboflavin synthase (RS). This invention relates to the isolation of nucleic acid fragments from plants or fungi that encode LS protein. The invention also relates to the isolation of nucleic acid fragments from plants or fungi that encode RS protein. In addition, the invention also relates to the construction of chimeric genes encoding all of a portion of LS, in sense or antisense orientation, wherein the expression of the chimeric gene results in production of altered levels of plant LS in a transformed host cell. Furthermore, the invention also relates to the construction of chimeric genes encoding all of a portion of RS, in sense or antisense orientation, wherein the expression of the chimeric gene results in production of altered levels of plant or fungal RS in a transformed host cell.

Abstract: The invention relates to high-level production of pHBA in green plants using a unique expression cassette. The latter comprises a chorismate pyruvate lyase (CPL) coding sequence operably linked to a suitable promoter capable of driving protein expression in higher plants. Additionally, the CPL cassette comprises a sequence encoding a chloroplast transit peptide, its natural cleavage site, and a small portion of the transit peptide donor protein fused to the N-terminus of CPL. The chloroplast targeting sequence targets the foreign protein to the chloroplast compartment and aids in its uptake into the organelle. The cleavage site is unique to the transit peptide, and cleavage of the chimeric protein encoded by the cassette at this site releases a novel polypeptide that has full enzyme activity, comprising the mature CPL enzyme and a small portion of the transit peptide donor.

Abstract: A system for channel assignment in a trunked transmission communication system including a plurality of subscribers. A plurality of subscribers is provided home channel assignment to reduce collisions. A home channel alias is provided for home channel coverage where a designated home channel is unavailable. A system for call grouping is provided to avoid talk group splitting. A first check is used to determine if other channels are conducting communications with identical home and talk group information. A second check is available after a temporary channel assignment. In one system both the home channel aliasing and call grouping are performed.

Abstract: A non-linear element is formed on a flexible substrate by securing the substrate to a rigid carrier, forming the non-linear element, and then separating the flexible substrate from the carrier. The process allows flexible substrates to be processed in a conventional fab intended to process rigid substrates. In a second method, a transistor is formed on a insulating substrate by forming gate electrodes, depositing a dielectric layer, a semiconductor layer and a conductive layer, patterning the conductive layer to form source, drain and pixel electrodes, covering the channel region of the resultant transistor with an etch-resistant material and etching using the etch-resistant material and the conductive layer as a mask, the etching extending substantially through the semiconductor layer between adjacent transistors.

Abstract: A switching control device for transmitting calls received by a cellular phone to a fixed-network telephone enables people to receive calls transmitted to a cellular phone by way of a fixed network telephone particularly equipped with a plurality of extension lines via conversion operations. It operates with a cellular phone/fixed network telephone switching device in cooperation with an on/off device. When a cellular phone receives an incoming call, the switching device will first detect the main telephone set and its extension lines of their individual status of use; and the on/off device is selectively actuated of its on and off states and also its vibration ring operation according to the detection. Thereby a user can pick up a nearest extension line without rushing back to a main telephone set when an incoming call is transmitted to a cellular phone.
