Figure 7From: Comparative transcriptomics in the TriticeaeHomologous clusters exhibiting greater intra-species than inter-species sequence similarities. These types of clusters are indicative of a gene duplication having occurred in wheat (Panel A) or barley (Panel B). The absence of a significant Blast hit between W2 and B (or B2 and W) is consistent with subsequent sequence drift of one member of the duplicated pair.Back to article page
