Putative host defense peptides (HDPs) encoded by S. gertschi transcripts. (A) Diversity of HDP-coding transcripts. The number of transcripts is the number of unique sequences that putatively encodes to different proteins of this subcategory. (B) The translated putative defensins aligned to reference precursor sequences. (C–E) The translated precursor sequences coding for possible members of the NDBP-2, -3, and -4 subfamilies, respectively, together with previously reported similar precursor sequences. The identity percentages (%I) in the alignments were calculated based on the precursor sequences. The predicted signal peptides are shown underlined, the mature peptides are shown in bold typeface, and the propeptides are shown in italics.
