The discovery of Mariam, a wheat-unique miniature transposable element family, was reported in our previous study. We have also shown the possible impact of Mariam insertions on the expression of wheat genes. However, the evolutionary dynamics of Mariam was not studied in detail. In this study, we have assessed the insertion sites of Mariam family in different wheat species. In-silico analysis of Mariam insertions has allowed the discovery of two different sequence versions of Mariam, and that Mariam might have been recently active in wild emmer wheat genome (T. turgidum ssp diccocoides). In addition, the analysis of Mariam insertional polymorphism has facilitated the discovery of large genomic rearrangement events, such as deletions and introgressions in the wheat genome. The dynamics of Mariam family sheds light on the evolution of wheat.

的发现 马里亚姆，我们以前的研究中报道了小麦独特的微型转座因子家族。我们还显示了可能的影响马里亚姆插入对小麦基因表达的影响。然而，进化动力学马里亚姆没有详细研究。在这项研究中，我们评估了马里亚姆 不同小麦品种的家庭。 硅内 分析 马里亚姆 插入允许发现两个不同的序列版本的 马里亚姆， 然后 马里亚姆 可能最近在野生Emmer小麦基因组中活跃（T. turgidum ssp 菊苣）。另外，分析马里亚姆插入多态性促进了大基因组重排事件的发现，例如小麦基因组的缺失和渗入。动态马里亚姆 一家人了解了小麦的进化。
