摘要:
The invention provides a high capacity binary shuttle vector having T-DNA region and Ri ori and capable to integrate a large genome fragment in it; a genomic library having the ability to transform a plant, especially monocotyledonous ones; a plant transformed with the high capacity binary shuttle vector; and a method of searching for a useful gene by use of the above vector. The present high capacity binary shuttle vector can introduce a large genome fragment of 10 kb or more, easily, efficiently and stably into a plant, especially monocotyledonous ones under those conditions in which the rearrangement or deletion of these genome fragments does not occur. The invention also provides some other vectors derived from the above Ri ori driven vectors, which can integrate circular genome library plasmids with a lox site, or which can efficiently transform plants with genes of arbitrary expression properties. The invention includes also the assessment method for the functions of genome fragments inserted in the above vectors by complementation assay. In addition, a useful gene or gene complex can be efficiently examined so its isolation is also made easy.

The present invention provides nucleic acid markers for rice blast resistance genes Pi-ta and Pi-ta2, which hybridize with any RFLP probes isolated from rice genomic DNA and are located within a distance of 2.0 cM from rice blast resistance genes Pi-ta or Pi-ta2. According to the present invention, it becomes possible to easily identify rice blast resistance genes and related genes from rice cultivars containing Pi-ta or Pi-ta2, thus promoting development and breeding of superior cultivars. It becomes also possible to easily carry out a resistance test of rice. This will open up way to create new resistance genes.

The silicon carbide-based catalytic body of the present invention comprises: a porous body of given shape comprising a first bonded structure formed by bonding a large number of silicon carbide particles as an aggregate to each other in a state that a large number of fine pores are present, and a catalyst containing an alkali metal and/or an alkaline earth metal, loaded on the porous body, characterized in that the catalyst is loaded via a crystalline coating film comprising an oxide and formed on at least part of the surfaces of the silicon carbide particles forming the first bonded structure. In the catalytic body, the catalyst such as NOx occlusion catalyst or the like, loaded thereon can maintain its activity over a long period.
摘要:
In diffusion weighted imaging, motion monitoring navigation echoes are measured at every measurement of data after applying an RF excitation pulse, and one of them is set as a reference navigation echo. The reference navigation echo and other navigation echoes are one-dimensionally Fourier-transformed, a linear phase gradient thereof is calculated from those data, a linear phase gradient of the reference navigation echo is compared with those of other navigation echoes, and it is judged whether a difference therebetween is within an acceptable value or not. An echo signal corresponding to a navigation echo having the above difference being larger than the acceptable value is judged that correction based on the navigated motion correction is not applicable therein, and the image is produced by using an echo signal measured along with a navigation echo having the difference being the acceptable value or less. In this manner, a motion component included in the echo signal used for producing the image is made uniform and motion artifacts are eliminated.
