Fig. 3From: A tetraploidization event shaped the Aquilaria sinensis genome and contributed to the ability of sesquiterpenes synthesisHomologous Alignments of Grape, Cacao, and A. sinensis Genomes. The 12 circles show the homology alignment of the homologous regions among grape (V), cacao (T), and A. sinensis (A) genomes, with the grape as a reference genome. The curved lines within the inner circle are colored according to the 7 ancestral eudicot (Eu) chromosomes and link the paralogous pairs on the 19 grape chromosomes generated by the ECH. Each circle is formed by short vertical lines that denote homologous genes, which are colored to indicate chromosome number in their respective source plant as shown in the color scheme at the bottomBack to article page
