摘要:

白化是水稻叶色突变中较常见的突变,其主要由叶绿素的缺失或叶绿体发育受阻造成的。白化非致死突变体在光合机理、生物发育调控和遗传育种等方面都具有较大的利用价值,越来越受到研究者的重视。随着分子生物学的不断发展,越来越多的控制水稻白化的基因被克隆,关于水稻色素代谢的机理也逐渐清晰。综述近几年国内外水稻白化突变体的研究进展,包括水稻白化突变体的来源、表型特点、细胞学特征、分子机理及育种应用,为水稻白化的研究提供参考。

Abstract:

Rice leaf albino is a kind of common mutation, caused by chlorophyll deficit or impaired chloroplast development. Non-lethal Rice leaf albino mutant provide important materials on revealing photosynthetic mechanism, and available germplasm to genetic breeding. With the continuous development of molecular biology, more and more rice genes are being cloned, and the mechanism of pigment metabolism is gradually clear. This review briefly summarized current progresses in rice leaf albino study, involving in their origination, cytological characteristics, molecular mechanism and potential values in breeding utilization.
