An NJ distance tree for Tic40 homologs from Brassica spp. Tic40 from A. thaliana (AtTic40) was used as an outgroup. The numbers on nodes are bootstrap values. Bvi, B. villosa; Bmo, B. montana; Bin, Brassica incana; Bca, B. carinata; Bju, B. juncea; Bna, B. napus; Bol, B. oleracea; Bra, B. rapa; Bni, B. nigra. B. incana, B. villosa, and B. montana belong to the B. oleracea species complex.
