Figure 5. Differences in the transcriptional profiles of larval
midgut genes 2 hours (n=12,622) and 17 hours (n=12,910) after the host
switch. After two hours most of the differentially expressed genes still
showed expression profiles specific for a response to Host 1 (yellow).
After 17 hours these patterns had largely changed and host-specific
responses to the second plant (green) as well as expression differences
that were not expected from the differences between the controls (blue,
orange) were found. Ud= Urtica dioica , Sc=Salix caprea,Ru=Ribes uva-crispa.
