From: Parallel loss of introns in the ABCB1 gene in angiosperms
Schematic representation of the gene structure variation in ABCB1 in selected members of the grass family and non-grass monocots. The 5′ and 3′ UTR regions and species names are color-coded to match. Species with the same color code and the same letter in parenthesis behind the species name have the same intron composition. Intron loss is shown by a red star and a minus (−) sign. The figure is not drawn to scale
