Abstract:The purpose of this study was to establish optimized ISSR system for Dendrocalamus minor var.amoenus.The single factor design was applied for optimizing five factors in ISSR amplification system,such as Mg2 +,dNTPs,Taq DNA polymerase,primer and template DNA concentration.The results showed that the optimal 20 μL ISSR-PCR reaction system for Dendrocalamus minor var.amoenus contained 3.0 mmol/L Mg2+,0.20 mmol/L dNTPs,1.25 U Taq DNA polymerase,0.6 μmol/L primer,10 ng DNA template,2 μL 10 × Buffer,8.55 μL ddH20.The amplification procedure was as follows:94 ℃ 5 min;94 ℃ 45 s,52.7 ℃30 s,72 ℃90 s,40 cycles;72 ℃ 10 main,4 ℃ for storage.Under this optimal ISSR amplification system,16 primers were screened with high polymorphism from 100 primers.The test showed that the system was stable,reliable and applicative.
