Establishment and Optimization of ISSR-PCR Amplification System for Ligusticum chuanxiong Hort
摘要
Abstract
[Objective] This study was to establish and optimize the ISSR-PCR reaction system for Ligusticum chuanxiong Hort. [ Method] Using genomic DNA of Chuanxiong leaf extracted via an improved CTAB method, single factor analysis was performed to investigate the impacts of DNA template concentration, Mg2+ concentration, dNTPs concentration, primer concentration, Taq DNA polymerase concentration on ISSR-PCR amplification and to optimize this system for Ligusticum chuanxiong Hort. [ Result] The ISSR-PCR amplification(25 μl) suitable for Ligusticum chuanxiong Hort. Was determined to be composed of 2. 5 μl of 10 × reaction buffer, 2.1 mmol/L MgCl2, 300 μmol/L dNTPs, 0.4 μmol/L primer, 1.0 U Taq DNA polymerase and 20 -40 ng genomic DNA. [ Conclusion] Our study laid basis for analyzing the genetic diversity of Ligusticum chuanxiong Hort. Resources distributed in 17 different areas of China.关键词
