Analysis of Tobacco cDNA Sequence Encoding a Tsi1 Protein.

(A) Nucleotide and deduced amino acid sequences of the Tsi1 gene. The EREBP/AP2 DNA binding domain is underlined. The basic amino acids that potentially act as a nuclear localization signal are shown in boxes, and an acidic C-terminal region that might act as a transcriptional activation domain is shown in italics. The Tsi1 sequence was submitted to GenBank under the accession number AF058827.

(B) Comparison of the deduced amino acid sequences of Tsi1, Pti6, and a putative Arabidopsis protein (Ara). The amino acid sequence of Tsi1 was aligned with the amino acid sequences of tomato Pti6 (GenBank accession number O04682) and a putative Arabidopsis protein (GenBank accession number T02896). Boxes represent perfectly conserved amino acids, and dashes indicate gaps introduced to maximize alignment.
