| Abstract: | The amino acid composition of 56 lectins/isolectins, isolated from 50 species belonging to 16 different tribes of the Papilionoideae, have been used to construct phylogenetic trees and maps of both the Papilionoideae and the tribe Vicieae. Despite some discrepancies, the phylogenetic tree obtained for the Papilionoideae seems to be relevant at the tribal level. However, results obtained for the tribe Vicieae clearly indicate that the amino acid compositions of whole lectins and their constituent subunits are not suitable for discriminating between the various genera and species within the tribe. These findings are discussed in the light of the contribution of other chemical characters to the phylogeny of these groups. |
