Ethylene Response Factor Sl-ERF.B.3 Is Responsive to Abiotic Stresses and Mediates Salt and Cold Stress Response Regulation in Tomato

Figure 6

Multiple amino acid sequence alignment of tomato Sl-ERF.B.3 with related amino acid sequences of tomato Sl-ERF.B.1, tomato Sl-ERF.B.2, Capsicum annuum CaEREBP-C4 (AAX20037.1), and Nicotiana tabacum NtERF4/ERF5 (Q40478.1). Conserved residues are shaded in black. Dark grey shading indicates similar residues in four out of five of the sequences. Alignments were made in ClustalW using the default parameters. The black bar above the sequences represents the ERF domain. Star represents putative MAP kinase phosphorylation site absent in Sl-ERF.B.3 sequence. Dashes show gaps in the amino acid sequences introduced to optimize alignment. Numbers show the positions of amino acid residues.
