摘　　要：以淹涝处理后的樱桃叶片和根系为材料,采用CTAB法、TaKaRa RNA提取试剂盒法和改良试剂盒法提取其总RNA,通过琼脂糖凝胶电泳和核酸蛋白检测仪比较所提取总RNA样品的质量。结果表明:改良TaKaRa RNA提取试剂盒法提取的总RNA完整性高,质量好,无降解;进一步采用改良TaKaRa RNA提取试剂盒法提取樱桃淹涝胁迫0—4 d叶片和根系的总RNA为模板进行RT-PCR验证,发现PCR扩增得到的条带较清晰,与目的片段大小一致。因此,改良TaKaRa RNA提取试剂盒法提取的樱桃叶片与根系总RNA完全可以满足进一步分子生物学研究的需要,是淹涝处理后樱桃总RNA提取的理想方法。Total RNA was isolated from leaves and roots of cherry under waterlogging through CTAB method,TaKaRa MiniBEST Plant RNA Extraction Kit and improved Extraction Kit method.The quality of the total RNA was tested by gel electrophoresis and Ultramicro nucleic acid∕protein detector.The results showed that total RNA extracted by improved TaKaRa MiniBEST Plant RNA Extraction Kit had two clear bands of 28S rRNA and 18S rRNA without degradation,and with higher purity and good integrity.Then,the total RNA of leaves and roots of cherry after 0-4 days waterlogging treatment were extracted by improved kit method,the quality of the RNA were determined by RT-PCR,the results showed that the PCR product had a distinct band with the same size as theoretical fragment and could satisfy the demands of molecular biology experiment.So the improved TaKaRa MiniBEST Plant RNA Extraction Kit method was the ideal method for the extraction of total RNA from cherry after waterlogging.
