Fig. 7. Analysis of GRP-related sequences from seed plants. (A) Amino acid alignment of the N-terminal region of proteins structurally similar to bean GRP1.8. The first 40 amino acids were used to perform multiple alignments. (B) Classification of plant proteins structurally similar to GRP1.8. The classification was based on multiple protein sequence alignments of the first 40 amino acids of proteins. The bootstrap values for the five main families are indicated at the nodes of the tree. N-terminal amino acid sequences were aligned with PILEUP and analysed with the neighbour-joining method.
