A three-step screening of selection for resistance against pathogenic bacteria infection, selection for resistance against pathogenic fungi infection, and selection for sensitivity to salicylic acid was carried out onlines highly expressing rice full-length cDNA (rice-FOXlines) which were prepared by using a FOX hunting system. As a result, oneline (line K15424) selected in all of the three types of screening was successfully selected. Line K15424 carries a rice full-length cDNA. Rice overexpressing AK070024 was produced, and resistance against rice bacterial leaf blight was assayed using the T1 generation. As a result, it was confirmed that AK070024-overexpressing rice is resistant against bacterial leaf blight and blast.

Rice gene capable of imparting wide-spectrum disease resistance

The present invention is directed to identify genes involved in the growth of a plant and provide a transformed plant the growth of which is promoted utilizing the genes.

Transformation of a plant to promote root and/or leaf growth

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

The present invention relates to methods of producing transgenic plants having resistance to blast fungus and/or leaf-blight bacteria by transforming the plants with a DNA encoding a protein that induces hypersensitive reaction-like lesion mimic, and transgenic plants, plant cells, seed and progeny having resistance to blast fungus and/or leaf-blight bacteria.

Methods for enhancing plant resistance to pathogens

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

The present invention relates to a method for disrupting a gene in a plant using a tobacco retrotransposon, comprising the steps of introducing the retrotransposon into the plant, and culturing and regenerating the plant, into which the retrotransposon is introduced, to produce a transformed plant.

Method for disrupting genes using tobacco retrotransposon

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

An oligonucleotide encoding a plant gene capable of controlling ethylene synthesis, comprising an oligonucleotide encoding an amino acid sequence from position 1 (Met) to 405 (Gln) of SEQ ID NO. 2 in SEQUENCE LISTING, or an oligonucleotide encoding a second amino acid sequence having one or several amino acid deletions, substitutions, or additions in the amino acid sequence.

Gene controlling ethylene synthesis

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.
