摘要: 为从越橘成熟组织中提取高质量DNA,对CTAB法进行改良,并与常规CTAB法及快速CTAB法的提取效果进行比较。结果表明:改良方法提取获得的DNA产量大、纯度高,DNA产量平均为192μg/g,OD260/OD280在1.75~1.85之间,所得DNA能被限制性内切酶完全消化,以其为模板进行SRAP-PCR扩增,能得到清晰、稳定的条带,证明改良方法适于越橘成熟组织DNA的提取。

关键词: 越橘, 成熟叶片, DNA提取, 改良CTAB法, SRAP

Abstract: To obtain high quality genomic DNA from mature tissues of blueberry( Vaccinium spp. ), a modif ied CTAB method was established.And then three different methods, the conventional CTAB method, rapid CTAB method and modi??fied CTAB method, were compared. The results showed that the modified method could obtain the expecting DNA thatreached the higher purity (OD260/OD280 is between 1. 75 and 1. 85) and higher yield ( 192 g/ g). Furthermore, the DNA can be digested completely with restriction endonuclease, and the electrophoresis bands of SRAP??PCR were clear and stable. It is concluded that this modified CTAB method should be suitable for extraction of genomic DNA from mature tissuesof blueberry( Vaccinium spp. ).

Key words: Blueberry( Vaccinium spp. ), Mature leaves, Genomic DNA extraction, Modified CTAB, SRAP
