Abstract
The most popular retrotransposon-based molecular marker system at the present time is the sequence-specific amplification polymorphism (S-SAP) system, which is widely used for various applications including phylogenetic analysis. In this study, we successfully developed a new S-SAP marker system based on FaRE1 retrotransposon in strawberry genome. Among 34 primer combinations used to develop the S-SAP marker system, seven primer combinations produced high quality and reliability banding patterns. A total of 288 polymorphic bands from 722 amplified bands were detected in 13 strawberry accessions, with a polymorphic ratio of 39.8%. Phylogenetic analysis showed that genetic coefficient ranged from 0.67 to 1.00 for 13 strawberry accessions. An 187bp S-SAP band was detected from 50 strawberry plantlets regenerated from leaves which were cultured on MS media supplemented with 1.0mg/l thidiazuron (TDZ) and 0.1mg/l 2,4-dichlorophenoxyacetic acid (2,4-D). The available evidences proved S-SAP marker had high level of polymorphism in strawberry accessions.
