Prosystemin cDNA

Fig. (1). The wound response in tomato plants. Tomato plants respond to wounding with the transcriptional activation and accumulation of Systemic Wound Response Proteins including defense proteins, proteolysis-associated proteins, signaling-associated proteins, and proteins of yet unknown function in plants defense. The change in gene expression can be monitored on SDS-PAGE gels. In comparison to control plants (I), treatment with systemin (II), or overexpression of the prosystemin cDNA (III) leads to the accumulation of SWRPs (arrowheads) and the downregulation of other, unidentified proteins (triangles). The figure was modified after [13].

Fig. (2). The primary structure of tomato (pro)systemin. The amino acid sequence deduced from the prosystemin cDNA is shown. The systemin precursor comprises 200 amino acids. The 18 amino acids of the systemin oligopeptide (bold, underlined) are located close to the carboxy terminus.
