摘要: 以模式植物拟南芥为例, 建立了一种克隆small RNA 分子的技术平台, 为今后开展small RNA 分子的生物学功能研究提供技术支撑。通过用抗病信号分子水杨酸(SA) 处理拟南芥叶片后, 进行small RNA 分子群体的分离与接头连接、PCR 扩增、T - 载体克隆与检测、测序分析和生物信息学分析等一系列实验, 成功地克隆了一些small RNAs, 并对其表达和功能进行了分析。

Abstract: We have developed a reproducible method of small RNAs cloning from model plant Arabidopsis thaliana , which will facilitate the research on small RNAs in the future .We have successfully cloned several small RNAs from leaves of Arabidopsis treated by SA ( signal molecule of disease resistance ) , using isolation , adapter ligation , PCR amplification , Tclone, sequence and bio-information analysis and so on . Furthermore , we conducted analysis on their expression profiles and predicted functions of these small RNAs .
