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
