A phylogeny for the DUF642-domain gene family indicates that two genes with differential expression in petals 40 are not the products of a recent duplication event

Genes with the plant-specific but functionally uncharacterized domain family DUF642 form three clades (A, B, and C). In addition to the genes with petal-specific expression patterns, Clade A includes asterid, , monocot and magnoliid genes, indicating that the clade predates the divergence of these lineages (Fig. 1). The genomes of basal-most angiosperm lineages (and Nymphaeales) and gymnosperms may also contain unsampled Clade A genes. Clade B genes were sampled from (Nymphaeales) and Clade C genes were identified from and . Bootstrap support values (>50%) are shown above each branch.
