Comparison of the amino acid sequences of various Fds

The amino acid sequence of the potato Fd I was compared with Fd sequences from other organisms: tomato (Fd I; John et al., 1997), tomato (Fd II; Kamide et al., 1995), Arabidopsis (Fd I; Somers et al., 1990), spinach (Fd I; Wedel et al., 1988), pea (Pisum sativum; Fd I, Dobres et al., 1987), maize (Fd I and II; Hase et al., 1991), spinach (Fd II; Takahashi et al., 1983), and Fd III from maize roots (Hase et al., 1991). The new potato Fd I sequence has been submitted to the National Center for Biotechnology Information GenBank (accession no. AJ307031). Asterisks, Identical amino acids; double points, highly conserved amino acids with double points; single points, conserved amino acids with single points. The alignments were performed with ClustalW (http://www2.ebi.uk/clustalw). Transit peptides, as far as available, and the mature proteins are compared.
