Deduced amino acid sequence of pepper CaCML13 and its sequence similarities to its orthologs in other plant species. (a) Comparison of deduced amino acid sequences of pepper CaCML13 to its orthologs in other plant species, amino acid residues that are conserved in at least five of the seven sequences are shaded, whereas amino acids identical in all seven proteins are shown in black, alignments were made in DNAMAN 7 (Lynnon Biosoft, USA) using the default parameters; (b) phylogenetic analysis of CaCML13 with its orthologs in other plant species including S. lycopersicum, S. tuberosum, N. tabacum, S. indicum, I. nil, J. curcas, C. sinensis and A. thaliana; (c) highly conserved EF-hand motifs in CaCML13.
