      The genome of the African tulip tree. (a) Flower of the African tulip tree. (b) Distribution profiles of 21-mer analysis of short reads. (c) Circos plot showing the genome details. Labels I-VII indicate: (I) 13 pseudo-chromosomes of S. campanulata; (II) gene density; (III) repeat sequence content; (IV) GC content density; (V) density of Copia LTR-RTs; (VI) density of Gypsy LTR-RTs; (VII) syntenic blocks (all window sizes = 50 kb).

    • Figure 2. 

      Comparative genomic analysis of the African tulip tree. (a) Expansion and loss of gene orthogroups leading to the current African tulip tree genome. (b) Venn diagram showing orthogroups shared by the African tulip tree and related genomes. (c) Syntenic dot plot between S. campanulata and V. vinifera. (d) The Ks distribution map within and between species.
