Significance Rice ( Oryza sativa ) has a unique combination of attributes that made it an ideal host to track the natural behavior very active transposable elements (TEs) over generations. In this study, we have exploited its small genome and propagation by self or sibling pollination identify characterize two strain pairs, EG4/HEG4 A119/A123, undergoing bursts nonautonomous miniature inverted repeat element mPing . Comparative sequence analyses these strains advanced our understanding i factors contribute sustaining TE burst for decades, ii features distinguish from in cell culture mutant backgrounds, iii extent which TEs can rapidly diversify inbred organism.
