Results obtained in this study differ from that reported for cyclophilin induction in potato tubers where
Fusarium eumartii
elicitors and salicylic acid had no effect on induction (Godoy
et al.
2000). These differences may reflect the existence of different CyP genes which are differentially regulated under stress conditions in cells and tissues of the potato plant. As yet, no systematic investigation into the organization of potato cyclophilin genes and the characteristics of their promoters has been performed
