“Unclassified/unknown” consensus sequences in the raw libraries that are classified by MCHelper. (A) The proportion of TEs originally labeled as “unclassified/unknown,” which were recovered by the three-step approach of MCHelper. (TR) terminal repeat. (B) Number of recovered TE sequences by TE order/class. Class I and Class II indicate all the elements that contain one or more retrotransposon-like domains in the first case or DNA-like domains in the latter case, but it was not possible to assign a deeper classification. EDTA is not included in this figure because the software does not report any “unknown/unclassified” elements.
