主要研究：Here, we leverage whole-genome resequencing data available for 602 cultivated and wild accessions to determine the contribution of transposable elements (TEs) to tomato diversity.

结果：We identify 6,906 TE insertions polymorphisms (TIPs), which result from the mobilization of 337 distinct TE families. Most TIPs are low frequency variants and TIPs are disproportionately located within or adjacent to genes involved in environmental responses. In addition, genic TE insertions tend to have strong transcriptional effects and they can notably lead to the generation of multiple transcript isoforms. Using genome-wide association studies (GWAS), we identify at least 40 TIPs robustly associated with extreme variation in major agronomic traits or secondary metabolites and in most cases, no SNP tags the TE insertion allele. 

结论：Collectively, these findings highlight the unique role of TE mobilization in tomato diversification, with important implications for breeding.

p.s. 这篇文章相对比较简单（但是工作量还是挺大的，属于思路简单，需要耐心和细心的活，当然还有服务器的计算能力），是对已发表数据的再分析。比较好的点：一个是选取的研究对象比较好，具有高质量的参考基因组和大规模的重测序数据，并且表型数据完整，可以做进一步的GWAS分析；二是研究方向比较好，目前关于植物中TE的深入研究还是不多，通过群体大数据对TE在基因组演化和群体遗传多样性中的作用研究就更少了，作者还是研究的番茄这个物种，对于未来的育种策略制定具有非常高的参考价值。
