图1 OsGRF4基因功能标记设计策略 SNP3为功能性多态位点, PF和PR为外引物, DR和XR为反向内引物, 分别与碱基AA和TC匹配。分别在DR和XR的3′端引入错配碱基C开发了DMR和XMR。箭头表示扩增方向。 |
Fig. 1 Strategy of functional markers design for OsGRF4 SNP3 indicates functional polymorphic sites; PF and PR are outer primers; DR and XR are reverse inner primers, which matching the bases AA and TC, respectively. A mismatch base C was introduced in the 3′ end of DR and XR to develop DMR and XMR. The arrows indicate amplification direction of the primers. |
