Conserved domains and phylogenetic tree of SlWRKY28. a The conserved retrotransposon gag and WRKY domain were found in the amino acid sequence. WRKYGQK was between 296 and 356 amino acids. b Phylogenetic trees based on the amino acid sequence of SlWRKY28 and homologous sequences from the GenBank database. The representative sequences reported in this study is marked with a black dot (●), as determined by a neighbor-joining analysis. The source of the sequence was indicated after each protein name
