Abstract: The stem of caulis spatholobi was used as the experimental material for DNA extraction using the improved CTAB method. The ISSR-PCR reaction system was optimized and constructed using orthogonal and single factor experiments. The results showed that the optimal ISSR-PCR reaction system for caulis spatholobi was DNA template 60 ng, Taq enzyme 2.00 U, Mg2+ concentration 1.75 mmol/L, dNTP concentration 0.25 mmol/L, primer concentration 0.20 μmol/L, and optimal annealing temperature 44.6 ℃. 20 ISSR primers suitable for caulis spatholobi from were selected 100 ISSR primers.

Key words: caulis spatholobi, ISSR, molecular markers, primer screening, orthogonal design, system optimization
