Intergenomic gene transfer (IGT) is continuous in the evolutionary history of plants. In this field, most studies concentrate on a few related species. Here, we look at IGT from broader perspective, using 24 We discover many events by assessing data nuclear, mitochondrial and chloroplast genomes. Thus, summarize two roles mitochondrion: source pool. That is, mitochondrion gives massive sequences integrates nuclear transposons tRNA genes. Though directions are opposite, lots likenesses emerge. First, pervasive all Second, single event certain shared ancestors during divergence. Third, sequence features homologies vary for different purposes donor recipient Finally, small repeats (or micro-homologies) contribute to mediating recombination genome.
