    • PROBLEM TO BE SOLVED: To provide a DNA having a promotor activity bringing a leaf specific expression, a recombinant plasmid containing the DNA and enabling the expression of an objective gene as leaf specific, and a transformed plant body introduced with the recombinant vector. SOLUTION: This DNA can function as a promotor shown in the following (a), (b) or (c). (a) A DNA consists of a specific base sequence derived from rice, (b) A DNA consists of a base sequence obtained by deleting, substituting or adding one or several bases in the DNA derived from the rice and having the promotor activity for bringing the leaf specific expression. (c) A DNA consists of the part of a specific base sequence derived from the rice and having the promotor activity for bringing the leaf specific expression. COPYRIGHT: (C)2005,JPO&NCIPI

    • PROBLEM TO BE SOLVED: To provide a method for effectively and inexpensively detecting methylation of a genome DNA. SOLUTION: In a RGLS method (Restriction enzyme Landmark Genome Scanning method), various detection of methylation of genome is carried out by cutting DNA of genome with a restriction enzyme which is a restriction enzyme recognizing 4 base group or 5 base group in a secondary restriction enzyme treatment before one-dimensional electrophoresis and a DNA digestion reaction of the enzyme is inhibited by methylation of the bases of the recognizing sequence and/or adjacent sequence. The effective and inexpensive detection of methylation of genome can be carried out by using a frequently cutting methylation sensitivity restricting enzyme. COPYRIGHT: (C)2005,JPO&NCIPI
    • 要解决的问题:提供一种有效且廉价地检测基因组DNA甲基化的方法。 解决方案:在RGLS方法(限制性酶标记基因组扫描方法)中,通过用限制酶切割基因组的DNA来进行基因组的甲基化的各种检测,限制酶是识别4个碱基或5个碱基的限制酶 在一维电泳和酶的DNA消化反应之前的第二限制酶处理被识别序列和/或相邻序列的碱基的甲基化抑制。 可以通过使用频繁切割的甲基化敏感性限制酶来进行基因组甲基化的有效且廉价的检测。 版权所有(C)2005,JPO&NCIPI
