Rapid and Recent Evolution of LTR Retrotransposons Drives Rice Genome Evolution During the Speciation of AA-Genome Oryza Species
The dynamics of long terminal repeat (LTR) retrotransposons and their contribution to genome evolution during plant speciation have remained largely unanswered. Here, we perform a genome-wide comparison of all eight Oryza AA-genome species, and identify 3911 intact LTR retrotransposons classified into 790 families. The top 44 most abundant LTR retrotransposon families show patterns of rapid and...
متن کاملConvergent Evolution of Ribonuclease H in LTR Retrotransposons and Retroviruses
Ty3/Gypsy long terminals repeat (LTR) retrotransposons are structurally and phylogenetically close to retroviruses. Two notable structural differences between these groups of genetic elements are 1) the presence in retroviruses of an additional envelope gene, env, which mediates infection, and 2) a specific dual ribonuclease H (RNH) domain encoded by the retroviral pol gene. However, similar to...
متن کاملEvolution of target specificity in R1 clade non-LTR retrotransposons.
Although most non-long terminal repeat (non-LTR) retrotransposons are inserted throughout the host genome, many non-LTR elements in the R1 clade are inserted into specific sites within the target sequence. Four R1 clade families have distinct target specificity: R1 and RT insert into specific sites of 28S rDNA, and TRAS and SART insert into different sites within the (TTAGG)(n) telomeric repeat...
متن کاملLTR Retrotransposons in Fungi
Transposable elements with long terminal direct repeats (LTR TEs) are one of the best studied groups of mobile elements. They are ubiquitous elements present in almost all eukaryotic genomes. Their number and state of conservation can be a highlight of genome dynamics. We searched all published fungal genomes for LTR-containing retrotransposons, including both complete, functional elements and ...
