Recently, it has been reported that transcripts
corresponding to a CyP gene from a wild potato
species (the ScCyP gene from S. commersonii )
accumulate in wounded leaves [15]. No information
is available on ScCyP gene expression in
tubers. Interestingly, whereas ScCyp gene expression
is stimulated in response to SA in leaves, SA
treatment does not affect StCyP gene expression
in tubers. These differences may reflect the existence
of different CyP genes which are differentially
regulated under stress conditions in tissues of
the potato plant.
