Myzus cerasi transcriptional responses to different hosts.

Myzus cerasi was maintained on American Land cress within our laboratory. However, we could not successfully infest cress with aphids taken directly off its primary host (cherry). However, when aphid were temporarily reared on Gallium the aphids were then able to colonise cress. Therefore, in order to infest cress we hypothesise that some transcriptional changes need to be induced, which are when aphid are reared on Gallium. We conducted RNAseq analysis of aphids reared on cherry, Gallium and cress. Differential expression analysis reveals a two-mode transcription response for M. cerasi: one for the primary host (Cherry) and a different set for its secondary hosts (Cress and Galium).
