Abstract The systemic induction of expression of the gene for proteinase inhibitor II after wounding different parts of potato (Solanum tuberosum L.) plants was analysed at the RNA level. Wounding of either leaves or tubers led to an induction of expression of this gene in non-wounded upper and lower leaves as well as in the upper stem segment, whereas no expression was observed in nonwounded roots or in the lower stem segment. The signal mediating the systemic induction in nonwounded tissue must therefore be able to move both acropetally and basipetally. The systemic wound response is specific for the expression of the proteinase-inhibitor-II gene as no influence was observed for the expression of genes encoding the small subunit of ribulose-1,5-bisphosphate carboxylase and the tuber storage protein patatin which were examined in parallel with the proteinase-inhibitor-II gene.
