Deduced Striga Expansin Amino Acid Sequences.
(A) SaExp1, SaExp2, and SaExp3 sequences are compared with each other and with the cucumber expansin CsExp2 by using the DNASTAR (Madison, WI) Megalign Clustal program. Conserved residues are shaded.
(B) Dendrogram of the coding regions of 20 different expansins without signal peptides. The positions of the SaExp sequences are indicated in the dendrogram by arrows. The GenBank accession numbers are as follows: AtExp1 (U30476), AtExp2 (U030481), AtExp5 (U30478), and AtExp6 (U30480) from Arabidopsis thaliana; CsExp1 (U30382) and CsExp2 (U30476) from Cucumis sativus; LeExp1 (U82123), LeExp2 (AJ239068), LeExp3 (AF059487), LeExp4 (AF059488), LeExp5 (AF059489), and LeExp6 (AAD13635) from Lycopersicon esculentum; OsExp1 (Y07782), OsExp2 (U30477), OsExp3 (U30479), and OsExp4 (U85246) from Oryza sativa; and GhExp1 (AF043284) from Gossypium hirsutum.
