FIGURE 3.
Gene locations and genomic duplication in maize (A) and Arabidopsis (B). SyMAP v3.4 (Soderlund et al., 2011) was used to depict the paralogous regions in the putative ancestral constituents of the maize (A) and Arabidopsis (B) genomes. Moreover, some relationship of orthologs or paralogs was confirmed with the Genomicus (http://www.dyogen.ens.fr/genomicus/) online tool (Louis et al., 2013). The segmental duplication regions are supposed to be colored with the same way to the relevant chromosome color. For example, the color key of maize chromosome 1 is red, which means that all red regions on the chromosomes are segmental duplicated from the chromosome 1. Using this method, we can get all of the paralogous regions among different chromosomes in the genome.
