| 摘 要： | 以马铃薯普通栽培品种"大西洋"的试管薯为材料,针对马铃薯块茎富含多糖和酚类化合物的特点,分别采用Chan法和Trizol法提取马铃薯块茎总RNA。结果表明,Chan法比Trizol法更适宜提取马铃薯块茎总RNA,该法提取的总RNA的28S、18S和5S rRNA条带清晰可见,无降解现象,未被蛋白质、多糖、酚类物质以及残余试剂所污染,且通过RT-PCR技术可以成功扩增出马铃薯腺苷二磷酸葡萄糖焦磷酸化酶AGPase小亚基基因。 |

| Abstract: | Potato tubers were rich in polysaccharides and phenolic compounds.To approach an effective method for total RNA extraction of tubers,two methods(Chan method and Trizol method) were used to extract the total RNA from tubers.The results indicated that Chan method was more suitable than Trizol method in the extraction of tuber total RNA.The total RNA extracted by this method showed clear bands of 28S,18S and 5S rRNA,and no degradation.There were also no pollution of protein,polysaccharides,phenolic compounds a... |
