Fig. 7: Model of the molecular regulation of wing dimorphism in planthoppers.
From: The transcription factor Zfh1 acts as a wing-morph switch in planthoppers

The balance of alternative wing morphs is regulated (i) transcriptionally by the Zfh1-FoxO cascade or (ii) post-translationally by the IIS-FoxO cascade. Components with increased expression levels are shown in bold and red. Components with decreased expression levels are shown in gray. FoxO-P, phosphorylated FoxO. The BPH images were illustrated by Miss Xin-Qiu Wang.
