DNA作为遗传物质,在生物进化、生长发育及生命代谢中具有重要地位和作用。湖北光敏感核不育水稻作为一个新的遗传种质资源,弄清其胞核DNA基因组的大小,不仅对于基础研究是必需的,而且对于生物工程和育种实践都是有益的。1 材料和方法材料:HPGMR(农垦58S)和农垦58原种(农垦58B)健康种子,用蒸馏水浸泡和冲洗,
As a genetic material, DNA plays an important role in the biological evolution, growth and development and life metabolism. As a new genetic germplasm resource, Hubei light sensitive nuclear sterile rice, clarifying the size of its nuclear DNA genome is not only necessary for basic research, but also useful for bioengineering and breeding practice. 1 Materials and Methods Materials: Healthy seeds of HPGMR (Nongken 58S) and Nongken 58 (Nongken 58B) were soaked and rinsed in distilled water,
