Figure 6.

Types of reconstructed phylogeny of homologous genes. Each reconstructed tree has one grape gene as the outgroup and its cacao ortholog. The reconstructed trees are divided into four types based on the location of the cacao gene or on genes with which plant species it grouped on the phylogenetic tree. A, The tree is of expected phylogeny; B, The cacao gene is grouped with durian homologs; C, The cacao genes are grouped with cotton genes; D, The cacao gene is grouped with but not outgroup to cotton and durian genes.
