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.
摘要:
The present invention concerns a method for enhancing yield-related traits in plants by modulating expression of a particular type of NAC transcription factor in plants. The particular type of NAC transcription factor is one having an amino acid sequence, which when used in the construction of a NAC phylogenetic tree, tends to cluster with the group of NACs comprising the amino acid sequence represented by SEQ ID NO: 2, SEQ ID NO: 51, SEQ ID NO: 53, SEQ ID NO: 55, SEQ ID NO: 57 or SEQ ID NO: 59 rather than with any other NAC group. The present invention also concerns plants having modulated expression of a nucleic acid encoding such a NAC transcription factor, which plants have enhanced yield-related relative to control plants. The present invention further concerns a method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding an AP2-2 polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding an AP2-2 polypeptide, which plants have enhanced yield-related traits relative to control plants. The present invention further concerns a method for enhancing yield-related traits in plants by modulating expression in a plant of a nucleic acid encoding an APETELA2-70-like (AP2-70-like) polypeptide. The present invention also concerns plants having modulated expression of a nucleic acid encoding an AP2-70-like polypeptide, which plants have enhanced yield-related traits relative to control plants. The invention also provides hitherto unknown NAC, AP2-2 and AP2-70-like-encoding nucleic acids, and constructs comprising the same, useful in performing the methods of the invention. The invention also provides constructs useful in the methods of the invention.

摘要:
The present invention relates to proteins, OsHDAC1, OsHDAC2 and OsHDAC3, which function as histone deacetylase, a gene coding for said proteins, and a method for producing a plant having a high growth rate by expressing said gene in the plant. According to the present invention, the OsHDACs proteins change the structure of chromatin to increase or decrease the expression of a foreign gene in the genomes, so that the expression amount of the OsHDACs proteins can be controlled to produce a plant having varied phenotypic characteristics. Particularly, the OsHDAC1 protein is expressed locally in the plant and increases the growth rate of plant by its overexpression and its expression is increased by ABA. Therefore, this protein can be very efficiently used for producing plants having a high growth rate even under stress conditions including drought, cold, etc., as well as under normal conditions.
