Fig. (3) Dendrogram based on amino acid sequence similarity of allergenic 2S albumins from different species (Ara h 6, peanut; Ber e 1, Brazil nut; Bra j 1, oriental mustard; BnIa and Bra n 1, rapeseed; Gly m 2S albumin, soya; Mat5-D, upland cotton; SFA-8, sunflower seed; Lup a 2S albumin, lupin; Ric c 1 and Ric c 3, castor bean; Ses i 1 and Ses i 2, sesame seed; Sin a 1, yellow mustard) visualized by using TreeView [141]. The lower bar indicates 10% identity. Horizontal line distances between branch points reflect the degree of homology.
