摘要: 以20个广泛栽培与应用的樱花品种为试材,基于特异SCAR分子标记的开发鉴别樱花品种。结果表明:4条SAPD引物和96对SRAP引物分别在20个樱花品种中的扩增得到了33条nSAPD多态片段和13条SRAP多态性片段,其中10条nSAPD和4条SRAP多态片段被成功转化为14个稳定可靠的特异SCAR标记。这14个SCAR标记在20个樱花品种中的分布不同,其中,‘普贤象'、‘松月'、‘御衣黄'、‘关山'、‘大提灯'和‘旭山樱'只有1个SCAR标记,‘郁金'、‘红丰'、‘咲耶姬'、‘朱雀'和‘菊垂樱'有2个SCAR标记,‘市原虎之尾'和‘平野妹背'有3个SCAR标记,‘八重红枝垂'和‘雨情枝垂'有4个SCAR标记,‘红笠'、‘红华'、‘一叶'、‘福禄寿'和‘杨贵妃'则没有SCAR标记。这些SCAR标记可作为品种特异性的DNA指纹,辅助用于20个樱花品种的鉴别,也可用于分子水平建立樱花品种分类鉴定系统。

Abstract: In the present study, 20 cultivars of flowering cherries(Cerasus), which were widely cultivated in gardens, were identified by developing specific sequence characterized amplified region(SCAR)markers from amplified polymorphic DNA(SAPD)and sequence-related amplified polymorphism(SRAP)techniques. Forty-six polymorphic bands(33 from SAPD and 13 from SRAP)among the 20 studied cultivars were obtained by using 4 SAPD primers and 96 SRAP primers. Fourteen(10 from SAPD and 4 from SRAP)of 46 polymorphic bands were converted into 14 stable and reproducible SCAR markers by designing specific SCAR primers from these sequenced polymorphic bands and by verifying PCR amplification with SCAR primers. The 14 SCAR markers was distributed in 20 different Cerasus cultivars. The cultivars C. serrulata var. lannesiana ‘Albo-rosea', C. serrulata var. lannesiana ‘Superba', C. serrulata var. lannesiana ‘Gioiko', C. serrulata var. lannesiana ‘Kanzan', C. serrulata var. lannesiana ‘Ojochin' and C. serrulata var. lannesiana ‘Asahiyama' possess only one SCAR marker, C.serrulata var. lannesiana ‘Grandifora', Cerasus × sieboldii ‘Beni-yutaka', Cerasus × yedoensis ‘Sakuyahime', C.serrulata var. lannesiana ‘Shujaku' and C. serrulata var. lannesiana ‘Plena-pendula' possess two SCAR markers, C. jamasakura ‘Albo Plena' and C. serrulata var. lannesiana ‘Imose' possess three SCAR markers, C. subhirtella ‘Plena Rosea' and C.subhirtella‘Ujou-shidare' possess four SCAR markers, and C. serrulata var. lannesiana ‘Benigasa', C. serrulata var. lannesiana ‘Kouka', C.serrulata var. lannesiana ‘Hisakura', C. serrulata var. lannesiana ‘Contorta' and C. serrulata var. lannesiana‘Mollis'possess no SCAR markers. These SCAR markers can be used as cultivar-specific DNA fingerprints to promote the identification of 20 Cerasus cultivars, as well as privide molecular data for the establishment of identification system of Cerasus cultivars and for the further study of Cerasus germplasm.
