Fig. 3: Expansion of cupin gene family in A. angustus.

a, A summary of the number of cupin genes from nine species based on a Pfam search of cupin_1 domain (PF00190). b,c, Phylogenetic trees show cupin genes in nine plant genomes: bicupins (b) and monocupins (c). The colour of each branch corresponds to the background colour for each species in a. The tandem duplicated gene clusters are ordered and shown on scaffolds of the A. angustus genome. The scale bars in the trees show the number of amino acid substitutions per site.
