Long terminal repeat-retrotransposons

WebRetroviruses and long terminal repeat (LTR) retrotransposons share a common structural organization. The main difference between these retroelements is the presence of a functional envelope (env) gene in retroviruses, which is absent or nonfunctional in LTR retrotransposons. Several similarities bet … WebAlthough long terminal repeat (LTR) retrotransposons are thought to have played an important role in plants, its distribution in grapevine is not clear. Here, we identified genome-wide intact LTR retrotransposons in a total of six high-quality grapevine genomes from Vitis vinifera L., Vitis sylvestris C.C. Gmel., Vitis riparia Michx. and Vitis amurensis Rupr. …
