Fig. 3From: Identification of cis-regulatory motifs in first introns and the prediction of intron-mediated enhancement of gene expression in Arabidopsis thalianaHexamer characteristics. Conservation and occurrence of hexamers in (a) first introns, (b) other introns, (c) Comparison of hexamers relative occurrence distributions of hexamers that occur more (blue, top x-axis)/ less (orange, bottom x-axis) often in first than in other introns. In (a) and (b), for definition of conservation, see Methods. Every dot represents a hexamer, the red line represents a computed running average, and the dashed black line corresponds to the respective estimated random conservation based on Eq. 2Back to article page
