摘要: 采用27 份不同来源的胡椒属( Piper) 材料和1 份不同属的草胡椒( Peperomia pellucida) 材料用引物OPQ-03 扩增得到一条约400 碱基对( bp) 卡瓦胡椒特异片段。对该片段进行了克隆和序列分析, 并根据序列分析结果将上述RAPD 分子标记转化为重复性和特异性更好的SCAR ( sequence characterized amplified regions, 序列特征化扩增区) 分子标记。本研究设计出了1 对卡瓦胡椒特异SCAR 引物P7. 1 ( 5′-GGT CAC CTC ACC GCA GCA GGA TGA ACG-3′) 和P7 . 2 (5′-GGT CAC CTC AAT GAC ATG GGA TGA ATC-3′) , 用这对特异引物对本次试验的28 份材料进行PCR 扩增, 结果只有不同属的草胡椒材料无任何扩增, 其它材料均扩增出了预期大小440 bp 的特异带。

Abstract: This paper studied on 28 pepper materials, including 16 cultivated papper materials, 3 wild pepper materials, 2 wild relatives of pepper materials , 6 kava ( Piper methysticum) materials, and 1 Peperomia pellucida materials. According to RAPD analysis, we generate SCAR marker for identifying Kava ( Piper, Piperaceae ) . A Kava-associated fragment with a length ofabout 400 bp was generated with OPQ-03 primer . The fragment was cloned and sequenced . PCR amplification with the specific primers P7 . 1 ( 5′-GGT CAC CTC ACC GCA GCA GGA TGA ACG-3′) and P7 .2 (5′-GGT CAC CTC AAT GAC ATG GGA TGA ATC-3′) was performed to 28 materials , which 27 materials amplified the 440 bp specific band except for Peperomia pellucida Kunth .
