Site-Specific Insertion Polymorphism of the MITE Alex-1 in the Genus Coffea Suggests Interspecific Gene Flow

Figure 3

Sequence alignment of C. canephora accessions displaying the absence of Alex-1 compared with BAC 46C02 sequence. The absence of a TSD indicates that the MITE was not excised from this site and that insertion never occurred. The accessions sequences were 739, 504, 738, 665, 663, 730, 321, 604, 345, 651, and 725 for wild accessions belonging to A, B, D, and E genetic diversity groups, and to the cultivated BD55 accession from Cameroon. Empty boxes: TSD. Black arrows: TIRs.
