Whole genome surveys of rice, maize and sorghum reveal multiple horizontal transfers of the LTR-retrotransposon Route66 in Poaceae.

ABSTRACT:

Background

Horizontal transfers (HTs) refer to the transmission of genetic material between phylogenetically distant species. Although most of the cases of HTs described so far concern genes, there is increasing evidence that some involve transposable elements (TEs) in Eukaryotes. The availability of the full genome sequence of two cereal species, (i.e. rice and Sorghum), as well as the partial genome sequence of maize, provides the opportunity to carry out genome-wide searches for TE-HTs in Poaceae.

Results

We have identified an LTR-retrotransposon, that we named Route66, with more than 95% sequence identity between rice and Sorghum. Using a combination of in silico and molecular approaches, we are able to present a substantial phylogenetic evidence that Route66 has been tr
