Evolutionary relationship between HMW-GSs alleles of S genomes and those ofGlu-A1,Glu-B1andGlu- D1. Phylogenetic analysis was constructed from nucleic acid sequence variations of the 5’ flanking promoter sequences, plus the sequences encoding the signal peptides and N-terminal regions. Both the network (a) and the neighbor-joining (b) tree indicated that all HMW-GS alleles are clustered into two groups (x-type and y-type subunits) which strongly support the close relationship between S genome HMW-GS alleles and those of D genome.
