Alignment of conserved regions within cereal SS genes. Comparisons of cereal SSs were made based on their deduced amino acid sequences and eight conserved regions identified. Conserved regions are shown in bold and transit peptides (where defined) are shown in gray. Amino acid sequences were deduced from genes encoding; wheat GBSS (Ainsworth et al., 1993), wheat SSI (Li et al., 1999), wheat SSII-A1 (this report), maize SSIIa cDNA (Harn et al., 1998), and the maize dull-1 gene (Gao et al., 1998). The sequences of the conserved regions are defined in Figure 2.
