Amino acid differences in IGMT2 (left) and IGMT4 (right) between DE155 and DE096. Corresponding amino acids in other genes and accessions are displayed for comparison, with N indicating the number of accessions with a specific configuration. Amino acid identities shared with DE155 in IGMT2 or IGMT4 are marked blue, while those shared with DE096 are shown in red. Amino acids affected by EGC are shaded in gray to indicate their inclusion within gene conversion tracts, and arrows indicate sites with shared polymorphisms in pairwise comparisons of gene loci. Notably, all 8 polymorphic amino acids distinguishing IGMT2 in DE155 from DE096 were affected by EGC, and likely originated from the IGMT3 locus. In contrast, EGC had a more limited effect on polymorphic amino acids in IGMT4.
