*Selected positions in the aligned consensus amino acid sequence (CAA) were selected from Figure S1 if they distinguished hairy from glabrous germplasm (dark arrows in Fig. S1) or were unique to B. villosa (*red arrows in Fig. S1). ND, not determined (sequence not available). NIL, missing amino acid. NA, not applicable. Note: Multiple gene copies are only indicated if an amino acid differed between the copies.
