We investigated Hopi/Osr27 (gypsy) and Houba/Tos5/Osr13 (copy) retrotransposon movements in 10-day-old roots and leaves of Oryza sativa cvs. Ipsala, Beser and Osmancik-97. Seeds from these three cultivars were germinated between filter papers in Petri dishes for 10 days. Three biologically independent (nonrelated) seeds were germinated for each cultivar. Then, roots and leaves grown from the same rice plant were harvested and used for genomic DNA isolation. Interretrotransposon amplified polymorphism polymerase chain reaction with suitable primers was performed with each DNA template to analyze the movements of Hopi/Osr27 and Houba/Tos5/Osr13 retrotransposons. Polymorphism ratios were evaluated both among cultivars and among roots and leaves from the same cultivar. The polymorphism ratios ranged from 0% to 17% for Hopi/Osr27 and from 10% to 87% for Houba/Tos5/Osr13. The obtained results at retrotransposon and varietal levels indicated that the retrotransposon type and genotype dependence are responsible for the occurrence of different variations. Transposable elements are very important for understanding the relationship between cultivars and evolution. Our findings are expected to contribute to the understanding of spontaneous genomic insertion events and their effects on the genetic and epigenetic changes during rice development.
