| 摘 要： | 蔷薇科苹果是一个典型的配子体型自交不亲和性果树树种,确定苹果品种的S基因型对于合理配置授粉树和杂交育种亲和性亲本选择具有重要意义.研究从苹果(Malus domestica)品种达尔文和金沙依拉姆中克隆得到了两个新S-RNase基因,分别命名为S53-RNase和S54-RNase,它们在GenBank上的登录号分别为FJ602074和FJ602075,并对46个苹果品种基因组DNA进行S等位基因特异性PCR扩增,鉴定了其S基因型. |
| 关 键 词： | 苹果 自交不亲和性 S-RNase基因克隆 S-基因型鉴定 |

| Abstract: | Apple(Malus domestica Borkh) is a typical Rosaceae species that exhibits gametophytic self-incompatibility(GSI).Identifying the S-genotypes of apple cultivars have the practical significance for selecting appropriate pollinated varieties and incompatibility parents for hybridization breeding.In this investigation two novel genes named S53-and S54-RNase respectively were cloned from apple cultivars Darling and Jinshayilamu.They were deposited in GenBank under the accession numbers of FJ602074 and FJ602075, r... |
