机译:IIIa型淀粉合酶的功能分析及新的淀粉生产方法

摘要

PPROBLEM TO BE SOLVED: To provide a rice SSIIIa mutant in which SSIIIa gene which is an essential material for clarifying functions of rice SSIIIa is knocked out and to provide a starch different from wild type by using the SSIIIa variant and to provide a method for producing the starch by using the SSIIIa variant. PSOLUTION: The present invention provides the rice SSIIIa mutant in which a synthase IIIa type (SS IIIa) gene in rice genome is knocked out and enzyme activity of starch synthase IIIa type is lost or remarkably lowered, compared with a wild type, and the starch produced by the rice SSIIIa variant and resulting from loss or lowering of enzyme activity of starch synthase IIIa type and different in physical properties from the wild type. The rice mutant and the method for producing the starch are also provided. PCOPYRIGHT: (C)2006,JPO&NCIPI

要解决的问题:提供一种水稻SSIIIa突变体,其中敲除了阐明水稻SSIIIa功能的重要物质SSIIIa基因,并通过使用SSIIIa变体提供了与野生型不同的淀粉,并提供了一种SSIIIa变体生产淀粉的方法。

解决方案:本发明提供了水稻SSIIIa突变体,其中与野生型相比,水稻基因组中的合酶IIIa型(SSIIIa)基因被敲除,淀粉合酶IIIa型的酶活性丧失或显着降低,以及由水稻SSIIIa变体产生的淀粉,是由于淀粉合酶IIIa型的酶活性的丧失或降低以及物理性质与野生型不同而产生的。还提供了水稻突变体和生产淀粉的方法。
