摘要(Abstract):

将高分辨率熔解曲线(high resolution melting curve analysis,HRM)技术应用于金银花种质鉴定中,对已知7对SSR(简单重复序列,simple sequence repeats)引物进行筛选,通过熔解曲线峰型及Tm差异,确定适合鉴别引物并考察其DNA模板浓度、退火温度及循环数的适宜范围。结合SIMCA-P软件对荧光信号进行处理分析,结果表明利用其中4对引物的熔解曲线可以区分金银花的3个主栽种质,为进一步完善金银花种质鉴定方法提供了依据。
To establish a new high resolution melting analytical method for identification of Lonicera japonica germplasm,the screening of 7 pairs of SSR( simple sequence repeats) primers,determining the suitable diagnostic primers by the differences of peak pattern and Tmwas conducted. Then into the DNA template concentration,annealing temperature and the suitable range of cycle number were investigated. Combined with SIMCA-P software for data processing analysis,the results show that three main germplasm honeysuckle could be divided by four sets of primers. It provides methodology for improving L. japonica germplasm identification.
