用PCR方法克隆延边地区膜荚黄芪的核糖体DNA ITS区域并进行序列分析。结果表明:延边地区膜荚黄芪ITS1的序列长度为228bp,5.8SrDNA长度为164bp,ITS2的序列长度为210bp;序列分析表明延边地区和甘肃的ITS1和5.8SrDNA完全一致,而ITS2第82位处有1个碱基的置换(T/C)。
用PCR方法剋隆延邊地區膜莢黃芪的覈糖體DNA ITS區域併進行序列分析。結果錶明:延邊地區膜莢黃芪ITS1的序列長度為228bp,5.8SrDNA長度為164bp,ITS2的序列長度為210bp;序列分析錶明延邊地區和甘肅的ITS1和5.8SrDNA完全一緻,而ITS2第82位處有1箇堿基的置換(T/C)。

With the method of PCR and bioinformatics,rDNA ITS region of Astragalus membranaceus from Yanbian was cloned and analyzed.The results showed that the length of rDNA ITS1,5.8 S rDNA and rDNA ITS2 for A.membranaceus from Yanbian were 228 bp,164 bp and 210 bp respectively,no difference was observed in rDNA ITS1 and 5.8 S rDNA sequences,but one base inversion(T / C)was observed at the 82nd sequence in rDNA ITS2 between Yanbian and Gansu.
