Abstract: To find the optimal simple sequence repeats(SSR) system for Betula luminifera,the cetyltrimethyl-ammonium bromide (CTAB) method was used to extract DNA from tender leaves,using the known primers from related species:B. platyphylla var. japonica and B. pendula. Then,one factor was changed at a time to optimize the polymerase chain reaction(PCR). Next,Polyacrylamide Gel Electrophoresis(PAGE) was used to detect the amplified products with three primers segments randomly selected from thirty-six pairs of primers and sequenced to further check the universality of the primer. Results showed that in a volume of 20 L,the optimal reaction system was 60 ng template DNA,1.500 mmolL-1 Mg2+,0.175 mmolL-1 deoxyribonucleotide triphosphate(dNTP)s,2.500 mmolL-1 primer,and 1.0 16.67 nkat Taq polymerase. Compared with B. platyphylla var. japonica and B. pendula,the optimal annealing temperature of the primer was 1C higher. The blast results from primer AF310851,AB084479,and AB084480 showed that the values of max ident were all above 95.0%. This indicated that the SSR primers of birch could be used with B. luminifera.[Ch,7 fig. 2 tab. 17 ref.]
