Background: Long terminal repeat (LTR)-retrotransposons (LTR-RTs) are ubiquitous and make up the majority of nearly all sequenced plant genomes, whereas their pivotal roles in genome evolution, gene expression regulation as well as their epigenetic regulation are still not well understood, especially...

The maize genome comprises 150,000–250,000 long terminal repeat (LTR)-retrotransposons, mostly in nested clusters, intermingled with other transpos-able elements and, more rarely, genes. All told, the genomic landscape of maize is 50–80% retrotransposons. Myriad families exist but >80% of ma...
6.Summary – LTR vs Non-LTR Retrotransposons What are LTR Retrotransposons? LTR retrotransposons are a type of retrotransposons that have long terminal repeats in their structure. Long strands of repetitive DNA can be found at each end of an LTR retrotransposon. These are known as long terminal ...

Keywords LTRretrotransposons;Plantgenomes;Structure;Transposing;Activity 转座子包括反转录转座子和转座子两大类[1]。反转录 转座子以RNA为介导,通过复制粘贴的方式进行转座,每转座一次,可增加一个拷贝,因此在真核生物基因组中含量很高,大多以高拷贝形式存在[2-3]。而转座子由DNA介导,通过剪切粘贴的方式进行转座...
