Abstract: The present invention relates to a method for increasing resistance of monocot plants against abiotic stress which comprises a step of transforming monocot plants with a recombinant plasmid containing a fused gene (TPSP) of trehalose-6-phosphate synthetase (TPS) gene and trehalose-6-phosphate phosphatase (TPP) gene to express the TPSP gene while maintaining normal growth and development characteristics. The present invention can increase the resistance of monocot plants against various stresses so that it can greatly contribute to the improvement of production and quality of valuable agricultural crops. The present invention also relates to a transgenic monocot plant, plant cell, or protoplast transformed with a nucleic acid encoding an enzyme for trehalose biosynthesis, under control of an inducible promoter, that increases tolerance to low temperature, salt, and water stress.

Abstract: The present invention relates to nucleic acid molecules configured to increase or decrease expression of a nucleic acid molecule that encodes a HrpN-interacting protein; nucleic acid constructs that include these nucleic acid molecules; host cells, transgenic plants, and transgenic plant seeds transformed thereby; and methods of increasing plant growth or imparting disease resistance to plants. Also disclosed are an isolated HIPM nucleic acid molecule and an isolated HIPM protein or polypeptide.

Abstract: An isolated nucleic acid construct including a nucleic acid molecule encoding a light-labile, phytochrome A, a light-inducible promoter which is 5? to the nucleic acid molecule encoding a light-labile, phytochrome A, and a terminator region which is 3? to the nucleic acid molecule encoding a light-labile, phytochrome A is disclosed. Methods for regulating a plant's canopy architecture and regulating a plant's seed yield, which involve transgenic plants or transgenic plant seeds including an isolated nucleic acid construct according to the present invention, are also disclosed.

Abstract: The present invention relates to a method for conferring tolerance to salt stress and drought stress in a monocot plant including transforming the monocot plant with an expression cassette comprising at least one ABRC unit, a minimal promoter, and a DNA molecule that increases tolerance to salt stress and drought stress in plants, wherein the at least one ABRC unit, the minimal promoter, and a DNA molecule are operably linked together to permit expression of the DNA molecule. The present invention also relates to a transgenic monocot plant transformed with a DNA molecule that increases tolerance to salt stress and drought stress operably linked to at least one ABRC unit and a minimal promoter.

Abstract: An isolated nucleic acid construct including a nucleic acid molecule encoding a light-labile, phytochrome A, a light-inducible promoter which is 5′ to the nucleic acid molecule encoding a light-labile, phytochrome A, and a terminator region which is 3′ to the nucleic acid molecule encoding a light-labile, phytochrome A is disclosed. Methods for regulating a plant's canopy architecture and regulating a plant's seed yield, which involve transgenic plants or transgenic plant seeds including an isolated nucleic acid construct according to the present invention, are also disclosed.

Abstract: The present invention relates to a transgenic monocot plant, plant cell, or protoplast transformed with a nucleic acid encoding an enzyme for trehalose biosynthesis, under control of an inducible promoter, that increases tolerance to low temperature, salt, and water stress.

Abstract: The present invention is directed to a method of producing a cereal plant cell or protoplast useful for regeneration of a water stress or salt stress tolerant cereal plant by transforming the cereal plant cell or protoplast with a nucleic acid encoding a late embryogenesis abundant protein. A transgenic cereal plant or cereal plant cell or protoplast transformed with a nucleic acid encoding a late embryogenesis abundant protein is also provided. An LEA protein gene, HVA1, from barley (Hordeum vulgare L.) was transformed into rice (Oryza sativa L.) plants. The resulting transgenic rice plants accumulate the HVA1 protein in both leaves and roots. Transgenic rice plants showed significantly increased tolerance to water stress (drought) and salt stress.

Abstract: A human-like proinsulin gene and its analogs, have been synthesized by a combination of chemical and enzymatic methods. A number of different human-like proinsulin gene analogs with altered C-chains have also been designed and can be readily constructed as described. As a part of the strategy, an adaptor for trimming DNA has been designed, synthesized and used to recover the A-chain insulin gene with the desired sequence from a hybrid plasmid; a related adaptor for trimming DNA has been designed to shorten the C-chain gene or any gene. The synthetic proinsulin gene has been joined to a replicable cloning vehicle and the hybrid DNA transferred to a host cell. The transformed host cell has been shown to contain the desired human-like proinsulin gene.

Abstract: Adaptor molecules have been prepared to comprise either start or stop signals for protein synthesis, in addition to recognition sites for restriction endonucleases. Separate adaptors may be used in a symmetrical duplex form. The start adaptor may include nucleotide base inserts to provide the correct reading frame of the triplet code in a DNA sequence with inappropriate reading frame. Insulin A-chain and B-chain genes of the human type, have been synthesized with the appropriate adaptor molecules provided on each end. The adapted DNA genes have been joined to replicable cloning vehicles and the hybrid DNA transferred to a host cell. The transformed host cell has been shown to contain the desired insulin gene.

Abstract: Synthetic oligonucleotides have been designed and prepared which are useful in the molecular cloning of a variety of DNA molecules. By means of such oligonucleotides, genetic informational material, e.g., DNA, can be joined to a cloning vehicle and transferred into host cells by transformation. Additionally, a method for determining whether genetic informational material has been transferred into transformed host cells has been developed.
