Abstract/Contents:"A large genetic variation is present for common bermudagrass [Cynodon dactylon (L.) Pers.] in the eastern Mediterranean, reported to be within the center of diversity for the species1. Cynodon, considered to be an autoploid2, includes all the ploidy series from diploids to hexaploids1 with base chromosome number of (x) 93. The region from Turkey to West Pakistan is recognized as the area of evolutionary activity for this species4. Bermudagrass is widely used in tropical and subtropical regions as a warm season turfgrass. Although number of protein coding genes do not vary much among plant species, their genome sizes differ greatly. Plant genomes commonly expand due to the copy-and-paste proliferation of a few long terminal repeat retrotransposons (LTRs)5. LTRs retrotranspose via an mRNA intermediate in a copy-and-paste process leading to extremely high copy numbers in the genome. Kalendar et al6 described the PCR-based iPBS marker system. The method is based on the virtually universal presence of a tRNA complement as a reverse transcriptase primer binding site (PBS) in LTR retrotransposons. Maize genome comprises of 85% repeat sequence, most of which constitute transposable elements7. In sorghum and rice, with around 500 Mbp genomes, transposable element fraction is about 30%8. As dispersed and ubiquitous transposable elements, LTRs are well suited as molecular markers. Phylogenetic analysis can help our understanding of evolution, history of polyploidization, and endemism, leading to current distributions. Understanding of associations among ploidy level and genetic diversity of Cynodon accessions may enhance our understanding of the evolutionary history of this warm season grass species. The objective of this study was to investigate associations between ploidy level and genetic diversity as assessed by iPBS retrotransposon marker, (2) determine whether retrotransposon gene family followed a similar evolution, and (3) correlate between retrotransposon marker and four nuclear molecular marker systems (SRAP, ISSR, POGP and RAPD) for Cynodon accessions' genetic analyses."
