Retrotransposons are major components of eukaryotic genomes and are present in high copy numbers. We developed retrotransposon-based insertion polymorphism (RBIP) markers based on long terminal repeat (LTR) sequences and flanking genome regions by using shotgun genome sequence data of mango (Mangifera indica L.). Three novel LTR sequences were identified based on two LTR retrotransposon structural features; a 5′ LTR located upstream of the primer binding site and a 3′ LTR showing high sequence similarity to the 5′ LTR. Starting with 377 unique sequences containing both 3′ LTR and downstream genome region sequences, we developed 82 RBIP markers that were applied to DNA fingerprinting of 16 mango accession. Five RBIP markers were enough to distinguish all 16 accessions. Our result showed that LTR identification from shotgun genome sequences was effective for development of retrotransposon-based DNA markers without whole-genome sequence information. We discuss application of the developed RBIP markers for identification of genetic diversity and construction of a genetic linkage map.
