A Gene Family Derived from Transposable Elements during Early Angiosperm Evolution Has Reproductive Fitness Benefits in Arabidopsis thaliana
(A) MUG phylogeny in nine angiosperm species. At, Arabidopsis thaliana; Bd, Brachypodium distachyon; Cp, Carica papaya; Mg, Mimulus guttatus; Mt, Medicago truncatula; Os, Oryza sativa; Sb, Sorghum bicolor; Vv, Vitis vinifera; Zm, Zea mays. See Figure S1 for sequences and Table S5 for locus IDs. All bootstrap values are >70% (not shown). Cp7 is truncated; its position is approximate. (B) Graphical representation of At-MUG1, At-MUG2, At-MUG7, and At-MUG8 gene transcripts. Bold horizontal lines represent transcripts, dips introns, and rectangles coding sequences.
