A phylogenetic tree was constructed, based on published predicted protein sequences for 13 legume genomes, including those of the newly annotated Trifolium subterraneum L. and A. thaliana. Mash v1.1 (Ondov et al., 2016) was used to calculate a distance matrix using k‐mer counting and pairwise mutation distance estimation, using the predicted amino acids from the published whole genome sequences for all the legumes, except Cajanus cajan, for which only the transcriptome assembly was used (as the whole genome assembly is not available). The tree was then constructed using UPGMA as implemented in the R‐package ‘phangorn’ v2.0.3. Shared and unique gene families were called using BLAST and OrthoMCL (Li et al., 2003). OrthomclToVenn (https://github.com/philippbayer/orthomcltovenn) was used to calculate the number of unique and shared genes between: (i) the Papilionoideae species and A. thaliana; (ii) the Millettioid, Galegoid and Dalbergioid clades; (iii) A. thaliana and the Lotus, Trifolium, Medicago and Cicer genera; and (iv) T. subterranean and T. pratense.
