From: Intron gain and loss in segmentally duplicated genes in rice
Extraction of the exonic 4-mers at the donor and acceptor splice sites of lost and retained introns. Duplicated rice gene 1 with a single exon and rice gene 2 and Arabidopsis orthologous gene with two exons and a single intron are shown in colored rectangles. Dashed lines indicate similar regions. Phylogeny analysis with Arabidopsis suggests an intron was lost in rice gene 1. The red ovals show the 4-mers extracted for SoR analysis.
