Fig. 3: Genome features and orthologous cluster analysis.

a Circos plot of features in G. trifoliata genome. Tracks from outer to inner circles indicate: chromosomes coloured by ancestral origin, gene density (each y-axis partition represents 100 k), the density of all annotated transposable elements (TE; each y-axis partition represents 200 k), the density of annotated Gypsy and Copia elements (each y-axis partition represents 50 k). The window size for all density tracks was 1 Mb. Orthologous cluster analysis (b, c) with a summary of orthologous clusters and singletons (b) and Venn-diagram of relationships between orthologous clusters (c) found in a comparison of annotated proteins from six Rosaceae species: G. trifoliata, apple²², pear³², peach¹⁷, strawberry⁷², and raspberry²⁰
