Systemic wound response protein

Systemic Wound Response Proteins in Tomato Plants... 

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].

There is no life without cells and there are no cells without membranes. The cell membrane of animal cells is very important in that it protects the organelles and also keeps undesired particles from entering the cell body. Proteins span the membrane and touch both the inside and outside of the cell. Their function is to interact with molecules outside the cell which includes the ability to serve as protein receptors for hormones, to bind to other cells in wound healing and in the immune response, and to transport molecules into and out of the cell. What is outlined in these few sentences, however, is a very complex biological system which has been described only phenomenologically for a long time. 

An example of a so-called primitive immune system, somewhat parallel to that in animals, is provided by the finding by Nelson et al. (29) that two proteinase inhibitors accumulate in leaves of tomato plants when attacked by chewing insects or mechanically wounded. The accumulation of the two antinutrient proteins is apparently a defense response and is initiated by the release of a putative wound hormone called the proteinase inhibitor inducing...
