Sequence analysis of the four defensin genes validated from the scorpion M. martensii
(a) BmKDfsin2. (b) BmKDfsin3. (c) BmKDfsin4. (d) BmKDfsin6. (e) Gene organization and structure analysis of four defensins from the scorpion M. martensii. Green letters represent exon sequences, and red letters are intron sequences. GT-AG splicing sites are shaded with blue background. The letters above the nucleotides are the corresponding amino acid sequences, the signal peptide regions are indicated by italics and bold letters, and the mature peptide regions are indicated with black letters. Cysteine residues are highlighted with yellow background.
