Wild grapevine genetic diversity in southeast Turkey has not been documented to date. In the present work, in order to clarify the relationships between wild and cultivated grape accessions from southeastern Turkey, 22 nuclear and three chloroplast microsatellite loci were used on 21 wild grapevine Vitis vinifera L. ssp. sylvestris (Gmelin) and 13 cultivated grapevine Vitis vinifera ssp. sativa accessions. The number of alleles per SSR locus ranged from 4 (VVIn16) to 20 (VVIv67) and the mean allele number per locus was 10.09. Expected locus heterozygosity ranged from 0.586 (locus VVIb01) to 0.898 (locus (VVIv67)). The three cpSSR molecular markers presented variation in size both in cultivars and in wild Turkish accessions. Two size variants were detected for cpSSR3 (106 and 107 bp) for cpSSR5 (104 and 105 bp), and for cpSSR10 (115 and 116 bp). The six alleles in wild grapevines fell into three haplotypes B, C and D. A genetic structure according to accessions taxonomic status (wild or cultivated) was revealed by UPGMA analysis. This highlighted a clear separation between domesticated and wild accessions in Turkish germplasm. The results pointed out the need to further collect and characterize this wild and cultivated grapevine germplasm.
土耳其东南部野生葡萄的遗传多样性迄今尚未见文献记载。在本研究中,为了阐明土耳其东南部野生葡萄和栽培葡萄品种之间的关系,对21份野生葡萄欧亚种野生葡萄(Gmelin)和13份栽培葡萄欧亚种栽培品种使用了22个核微卫星位点和3个叶绿体微卫星位点。每个SSR位点的等位基因数量从4个(VVIn16)到20个(VVIv67)不等,每个位点的平均等位基因数为10.09。预期位点杂合度范围从0.586(VVIb01位点)到0.898(VVIv67位点)。三个cpSSR分子标记在栽培品种和土耳其野生品种中均呈现出大小变异。检测到cpSSR3有两个大小变异(106和107 bp),cpSSR5有两个大小变异(104和105 bp),cpSSR10有两个大小变异(115和116 bp)。野生葡萄中的六个等位基因分为三个单倍型B、C和D。通过UPGMA分析揭示了根据品种分类地位(野生或栽培)的遗传结构。这突出了土耳其种质中驯化品种和野生品种之间的明显分离。结果指出需要进一步收集和鉴定这种野生和栽培葡萄种质。
