Schemes of iPBS and REMAP. A) iPBS is an efficient method which isolates long terminal repeat (LTR) sequences of retrotransposons [32]. Most fragments that are amplified between two retrotransposons by iPBS primers annealed at primer binding sites (PBS) contain putative LTR sequences. B) Retrotransposon and microsatellite amplified polymorphism (REMAP) amplified DNA fragments located between LTRs proximal to simple sequence repeats (SSRs).
