Fig. 2. (A). Multiple alignment of the deduced amino acid sequence of OAS-TL. The sequences from rice (Accession No. Q9XEA8), Arabidopsis (Accession No. NP_193224), and E. coli (Accession No. P11096] are aligned with that of the soybean sequences from this study (Accession No. AF452451). Positions of amino acid identity are shaded black and similar residues are shaded in gray. (B) Phylogenic tree of OAS-Tl. The phylogenic tree was constructed using the University of California database. Cytosolic isoforms: Glycine max (Accession No. AF452451), Arabidopsis thaliana (Accession No. NP_193224), Solanum tuberosum (Accession No. BAB20861), Brassica juncea (Accession No. O23733), Spinacea oleracea (Accession No. Q00834), Citrulus lanatus (Accession No. Q43317), Oryza sativa (Accession No. Q9XEA8), Zea mays (Accession No. P80608), Allium tuberosum (Accession No. BAA93051), and Triticum aestivum (Accession No. P38076). Chloroplastic isoforms: Capsicum annuum (Accession No. P31300), Spinacea oleracea (Accession No. D14722), Nicotiana tabacum (Accession No. AJ299249), Solanum tuberosum (Accession No. O81155), and Arabidopsis thaliana (Accession No. S48695). Mitochondrial isoform: Arabidopsis thaliana (Accession No. X81973). Bacterial OAS-TL: Escherichia coli (Accession No. P11096), Nostocaceae (Accession No. NC_003272), Thermosynechococcus elongates (Accession No. NC_004113), Synechocystis (Accession No. P73410), and Mesorhizobium loti (Accession No. NC_002678).
