湖北光周期敏感核不育水稻具有长日照诱导不育,短日照诱导可育和不育性易于转育等特性,是选育新品种的十分有用的杂交亲本,同时,也是研究高等植物基因结构和基因表达的好材料。为了从基因水平上对此材料进行深入研究,了解在不同光照条件下HPGMR育性转换的分子机制,首先必须获得高纯度高分子量的DNA。 Hubei Photoperiod Sensitive Genic Male Sterile Rice has the characteristics of long-day-light-induced sterile, short-day-induced fertility and easy translocation of sterility, which is a very useful hybrid parent for breeding new varieties. At the same time, it is also to study the genetic structure of higher plants And good material for gene expression. In order to further study this material at the gene level, understanding the molecular mechanism of fertility conversion of HPGMR under different light conditions, we must first obtain high purity and high molecular weight DNA.
