摘要:
This invention is directed to a monopartite RNA viral vector comprising modified tobravirus RNA-1 comprising an inserted foreign RNA sequence. This invention is also directed to a bipartite RNA viral vector derived from a tobravirus, wherein the vector comprises one or more foreign RNA sequences. The invention is directed to a method of silencing one or more endogenous plant host genes and a method of simultaneously silencing a plant host gene and expressing a foreign gene in a plant host. Such methods comprise infecting a plant host with a bipartite vector comprising modified tobravirus RNA-1 and RNA-2. The invention is further directed to a method of compiling a plant functional gene profile, a method of changing the phenotype or biochemistry of a plant host, and a method of determining the presence of a trait in a plant host, using a monopartite or bipartite viral vector derived from a tobravirus.

The present invention relates to a method for conferring herbicide, pest, and disease resistance in plant hosts. Specifically, the present invention employs transient viral expression vectors to express proteins or enzymes conferring resistance in plant hosts. In addition, a library of nucleotide sequence variants in a sense or antisene orientation may be used to determine the targets of an herbicide or pathogen and to screen suitable viral nucleic acids for herbicide, pest, and disease resistance.

Two novel genomic clones, ZZA1 and ZZA2, were isolated which encode for Pichia pastoris alcohol oxidase isozymes. The 5' non-coding region of ZZA1 contains common structural features involved in the transcription and translation of eukaryotic genes. Comparison of the nucleotide sequences of the ZZA1 and AOX1 51 noncoding regions showed that they are 66% similar to each other.The rice .alpha.-amylase gene OS103 was placed under the transcriptional control of the ZZA1 promoter. The nucleotide sequences of ZZA1 and other methanol-regulated promoters were analyzed. A highly conserved sequence (TTGNNNGCTTCCAANNNNNTGGT) (SEQ ID NO:2) was found in the 51 flanking region. A yeast strain containing the ZZA1 -OS103 fusion and secreting biologically active a-amylase into the culture media while converting starch to ethanol was produced. The ZZA1 and ZZA2 regulatory sequences may be used to contol the expression of other heterologous proteins in multiple yeast species.Methods of purifying proteins that are regulators of alcohol oxidase expression (referred to as AOER proteins) and methods of isolating these proteins are also provided.The invention also provides for the efficient conversion of starch into ethanol.

The present invention provides a method to personalize and enhance the value of consumer items for use in outdoor activities. It utilizes radio frequency identification (RFID) tags, computers, PDAs, and cell phones to link, record, and retrieve positional, personal, and historical data. The personalization and association of an object to a unique event by the consumer will lead to enhanced value of the product. Information that is stored on cell phones, PDAs, computers, and external databases are transferred as multimedia messages. The information is cataloged and organized using the unique RFID number. The subject line of the multimedia message is the RFID tag number. Commercial items such as skis, coats, hats, shoes, shirts, pants, gloves, sun glasses, surfboards, bicycles, wetsuits, cell phones, computers, golf clubs, golf balls, fishing poles, and lures will be produced that contain RFID tags.
摘要:
The invention provides novel genetic constructions for the expression of inhibitory RNA in the cytoplasm of eukaryotic cells. The inhibitory RNA may be an anti-sense RNA or a co-suppressor RNA, and functions to reduce the expression of a gene of interest in the target cell. The genetic constructions of the invention are capable of replicating in the cytoplasm of a eukaryotic cell and comprise a promoter region in functional combination with an encoding polynucleotide. The genetic constructions may be designed so as to replicate in the cytoplasm of plant cells, yeast cells, and mammalian cells. When the eukaryotic cell of interest is a plant cell, the genetic construction is preferably derived from a plant RNA virus. Plant RNA virus derived genetic constructions may employ a plant virus subgenomic promoter, including subgenomic promoters from tobamoviruses in functional combination with the RNA encoding region. In a preferred embodiment of the invention, plant cells are induced to produce elevated levels of the carotenoid phytoene. The elevated levels of phytoene are achieved by inhibiting the expression of the enzyme phytoene desaturase using the vectors of the invention.

The present invention is directed to a process for producing melanins, their precursors and their analogues, hereinafter referred to generically as melanins. According to the invention, melanins are produced in amounts greater than about 3.3 grams wet weight per liter of growth medium. The enhanced production of melanin can be achieved by manipulating the constituents of the growth medium, and/or attenuating fermentations conditions, and/or by genetically engineering microorganisms to produce melanins, and/or mutating the microorganisms.
