| Abstract: | The study focuses on insertions of perfect direct repeats of words of arbitrary length in plastomes and mitochondriomes. The approach is exemplified using seed plants. Plastomes of close species were analyzed to further develop and refine published evidence for the evolution of non-coding DNA. The results suggest that perfect repeats are common elementary events resulting from replication errors—duplication of DNA. The role of such duplications in the evolution of the plastome is discussed. |
