The present invention discloses that by combining different di TPS enzymes of class I and class II different diterpenes may be produced including diterpenes not identified in nature. Surprisingly it is revealed that a di TPS enzyme of class I of one species may be combined with a di TPS enzyme of class II from a different species, resulting in a high diversity of diterpenes, which can be produced.

The present invention relates to a gene encoding trehalose-6-phosphate phosphatase and use thereof, in particular, a yeast for practical use with superior resistance property to dryness and/or low-temperature storage, alcoholic beverages produced with said yeast, and a method for producing said beverages. More particularly, the present invention relates to a yeast, whose resistance property to dryness and/or resistance property to low-temperature storage is enhanced by amplifying expression level of TPS2 gene encoding a trehalose-6-phosphate phosphatase Tps2p in brewer's yeast, especially non-ScTPS2 gene specific to a lager brewing yeast and to a method for producing alcoholic beverages with said yeast, etc.
摘要:
The present invention relates generally to the field of molecular biology and concerns a method for enhancing various economically important yield-related traits in plants. More specifically, the present invention concerns a method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding a CLC-like (Chloride Channel-like) polypeptide, or an OsBURP-like (BURP-domain containing protein) polypeptide, or an AP2/ERF polypeptide or a protein fusion comprising a TPS (trehalose-6-phosphate synthase) and a TPP (trehalose-6-phosphate phosphatase) polypeptide or modulating one or more nucleic acid encoding a TPS and a TPP enzyme, whether comprised in the same or in separate molecules. The present invention also concerns plants having modulated expression of a nucleic acids and constructs comprising them, useful in performing the methods of the invention.
摘要:
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.

This invention relates to isolated nucleic acid fragments encoding trehalose metabolism enzymes, more specifically, alpha, alpha-trehalase, alpha, alpha-trehalose-phosphate synthase or trehalose-6-phosphate phosphatase. The invention also relates to the construction of a recombinant DNA construct encoding all or a portion of the alpha, alpha-trehalase, alpha, alpha-trehalose-phosphate synthase or trehalose-6-phosphate phosphatase, in sense or antisense orientation, wherein expression of the recombinant DNA construct results in production of altered levels of the alpha, alpha-trehalase, alpha, alpha-trehalose-phosphate synthase or trehalose-6-phosphate phosphatase in a transformed host cell.
