Fig. 2: Aegilops genome evolution.
From: The Aegilops tauschii genome reveals multiple impacts of transposons
a, Circos plot showing the syntenic regions in the Ae. tauschii genome detected by MCScanx. b, Synteny comparisons of Ae. tauschii chromosomes 1 and 3 to the genomes of rice and sorghum. Quota ratios of the alignments are shown above the dot plots. c, K s value distributions of 9,569 Aegilops paralogues identified from best reciprocal BLASTP searches. Coloured lines superimposed on K s plots represent significant components identified via a likelihood mixture model implemented in EMMIX. Each component is written as ‘colour/mean K s value/proportion’, where colour is the component (curve) colour and proportion is the percentage of duplicated genes assigned to the identified component. There are four components: grey/0.03/0.04, red/0.23/0.44, green/0.72/0.45 and blue/1.71/0.07. The smaller plot represents the same distribution after removal of the tandem duplicates. The four components are grey/0.04/0.04, red/0.23/0.33, green/0.70/0.55 and blue/1.71/0.08. d, Density plot of K s values of best reciprocal BLASTP hits in the genomes of Ae. tauschii, B. distachyon, O. sativa, S. bicolor and Z. mays. Density distribution of K s values of Ae. tauschii syntenic anchor gene pairs.
