Abstract
Transposable elements (TEs) are major contributors to genome plasticity and thus are likely to have a dramatic impact on genetic diversity and speciation. Recent technological developments facilitated the sequencing and assembly of the wheat genome, opening the gate for whole genome analysis of TEs in wheat, which occupy over 80% of the genome. Questions that have been long unanswered regarding TE dynamics throughout the evolution of wheat, are now being addressed more easily, while new questions are rising. In this review, we discuss recent advances in the field of TE dynamics in wheat and possible future directions.
摘要
转座元件（TEs）是基因组可塑性的主要贡献者，因此可能对遗传多样性和物种形成产生巨大影响。最近的技术发展促进了小麦基因组的测序和组装，为小麦中转座元件的全基因组分析打开了大门，这些转座元件占据了基因组的80%以上。长期以来关于小麦整个进化过程中转座元件动态的未解决问题，现在更容易得到解答，同时新的问题也在不断出现。在这篇综述中，我们讨论了小麦中转座元件动态领域的最新进展以及可能的未来发展方向。
