A The phylogenetic tree was constructed using OrthoFinder based on the reported genome information. Synthetic genes or non-synthetic genes were marked by different colors, and the ancestral collinearity gene cluster was first identified in the early-diverging angiosperm A. trichoppda. B The length distribution of syntenic blocks among angiosperms. C The gene numbers localized in syntenic blocks among angiosperms. D The phylogenetic relationship of OSCs, P450s, and BAHDs, which are localized in the BAT BGCs. The different colors represent the correspondingly catalytic activities in the biosynthesis of 2. E The evolutionary model of BAT BGCs following many tandem duplications, gene insertions, gene losses, and WGDs. The model illustrates that the BAT biosynthetic genes were swapped and duplicated into the gene cluster and subsequently evolved the accumulation of species-enriched BAT triterpenoids. I insertion, L loss, TD tandem gene duplication. Source data are provided as a Source Data file.
