水稻谷蛋白突变体的研究现状与展望

 水稻 (OryzasativaL .)是基因组研究的模式植物。随着培育功能性专用品种日渐成为水稻育种的重要目标 ,作为研究真核生物基因表达调控理想材料的谷蛋白突变体也为功能性专用水稻品种的选育提供了优良的遗传资源。利用低谷蛋白突变体可以培育肾脏病和糖尿病患者专用的低谷蛋白水稻品种。笔者在概述水稻谷蛋白突变体的主要类型及其突变的遗传规律的基础上 ,结合其它作物中的成功范例着重介绍了低谷蛋白突变体的研究现状 ,探讨了后基因组学时代适用于功能性育种的水稻谷蛋白突变体的相关研究方向。

Status and Perspectives on the Researches of Rice Glutelin Mutants

Rice (Oryza sativa L.) is a model plant for genomic researches. As the raising of functional rice breeding for special usage, glutelin mutants play more and more important role in the functional breeding as well as in the researches on eukaryotic gene expression regulation. The rice cultivar special for the patients suffering from kidney disease and diabete could be developed from the rice glutelin mutants. Current researches on characterization, mutation mechanism and breeding usage of various rice glutelin mutants, especially the low glutelin content cultivars were discussed in this paper with perspectives on the trends of the glutelin mutant researches in the era of post genomics.
