Genes in the cytochrome P450 family have evolved a wide range of functions. Here, Liu et al. reconstruct the evolution of the P450 genes CYP98A8 and CYP98A9in the Brassicales, revealing a complex history of retrotransposition, tandem duplication and neofunctionalization, followed by subfunctionalization or gene loss in specific lineages.
