Patent number: 9127290Abstract: 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 on Arabidopsis thaliana lines highly expressing rice full-length cDNA (rice-FOX Arabidopsis lines) which were prepared by using a FOX hunting system. As a result, one Arabidopsis thaliana line (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.Type: GrantFiled: March 4, 2009Date of Patent: September 8, 2015Assignees: National Institute of Agrobiological Sciences, RikenInventors: Masaki Mori, Nagao Hayashi, Shoji Sugano, Hiroshi Takatsuji, Hirohiko Hirochika, Kenji Oda, Minami Matsui

Publication number: 20120073023Abstract: 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.

Patent number: 7566815Abstract: 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.Type: GrantFiled: August 30, 2002Date of Patent: July 28, 2009Assignee: National Institute of Agrobiological Sciences and National Agricultural and Bio-oriented Research OrganizationInventors: Makoto Takano, Hirohiko Hirochika, Akio Miyao
