Amino acid alignment of SlRALF with the pollen-expressed SlPRALF, PhanthRALF, and AtRALFL4. The underlined section of the alignment corresponds to the predicted signal peptide sequences, the dibasic site within the proregion is identified with an arrow, and the conserved Cys residues are indicated with asterisks. Identical residues are boxed in black, and similar residues are shaded gray. The predicted amino acid sequence encoded by the Pol2 cDNA differs from SlPRALF at a single Arg residue in the mature peptide (underlined and indicated by the caret), which in Pol2 is a His. Vegetatively expressed SlRALF corresponds to the translated tomato unigene SGN-U316452, SlPRALF corresponds to the translated pollen-expressed tomato unigene SGN-U324197, PhanthRALF corresponds to the translated P. hybrida anther-expressed unigene SGN-U207478, and AtRALFL4 corresponds to the translated Arabidopsis pollen-expressed At1g28270 gene.
