This invention is intended to allow accumulation of large quantities of soluble sugars in tissue other than plant seeds. A plant is modified so as to suppress a gene encoding a subunit exhibiting the highest sequence similarity with the subunit encoded by the AGPL1 gene of rice among subunits constituting.

Plant variant, method for producing plant variant, and method for accumulating soluble sugar

It is intended to provide a polynucleotide encoding a gene capable of regulating tillering and leaf morphology in a plant and a method of regulating the phenotype of a plant by using this polynucleotide. The above-described polynucleotide can regulate the number of leaves or roots per individual or leaf morphology (including the length, width and thickness of leaves). In an embodiment, the plant usable in the regulation of tillering and leaf morphology is a monocotyledon. In a preferred embodiment, the monocotyledon is a gramineae plant. In a still preferred embodiment, the gramineae plant is rice.

Gene regulating tillering and leaf morphology in plant and utilization of the same

Rice phyC mutants were isolated using a mutant panel isolation method. When the mutants were grown under long-day photoperiodic conditions, it was found that they flowered (exposed their panicles (heads)) about one week earlier than the control rice. The results indicate that suppression of PHYC gene expression can promote plant flowering under long-day conditions. Utilization of the PHYC gene for promoting plant flowering will contribute substantially to breed improvement, for example, by facilitating the creation of useful agricultural crops and decorative plants that have a new characteristic adaptable for other cultivation areas and times. The rice phyC mutants described herein, which promote flowering under long-day conditions, will be highly prized as a new early-harvest rice cultivar.

Control of plant flowering time by regulation of phytochrome c expression

A polynucleotide encoding a plant gene capable of controlling disease resistance reactions in plants is provided which includes a polynucleotide having a nucleotide sequence encoding amino acid sequence from methionine at position 1 to Serine at position 361 of SEQ ID NO: 2 in the sequence listing, or having the amino acid sequence having one or several amino acid deletions, substitutions and/or additions, and being capable of controlling disease resistance reactions.

Isolated gene controlling disease resistance activity in plants and use thereof

A gene encoding a protein capable of controlling salt stress tolerance is provided. A polynucleotide encoding a plant gene capable of controlling salt stress tolerance is provided. The polynucleotide includes a polynucleotide which has a nucleotide sequence encoding an amino acid sequence from methionine at position 1 to asparagine at position 243 of SEQ ID NO: 2 in the sequence listing, or which has a nucleotide sequence encoding the amino acid sequence having one or several amino acid deletions, substitutions and/or additions and is capable of controlling salt stress tolerance.

Rice gene for controlling tolerance to salt stress

There is provided a polynucleotide encoding a plant gene capable of controlling a signal transduction system for brassinosteroid hormone, the polynucleotide encoding an amino acid sequence from Met at position 1 to Arg at position 1057 of SEQ ID NO: 2 in the SEQUENCE LISTING, including any polynucleotide encoding an amino acid sequence in which one or more amino acids are deleted, substituted or added to the amino acid sequence.
