The transcription factor bZIP63 is a key regulator of the starvation response in the model plant Arabidopsis thaliana and is directly targeted by the kinase SnRK1.

Young defense metabolites are often believed to be solely outputs but evidence suggests that they can regulate ancient signaling pathways.

Plant autophagy contributes to antiviral defense against geminiviruses by targeting one or more viral proteins for degradation.

A viral protein hijacks the key effector of transcriptional gene silencing, Su(var)3-9, to evade host plant surveillance.
