Model summarising the current understanding of signalling events that confer hormone activity in cold adaptation. In blue are transcription factors (TFs) and components of hormone signalling pathways, which are regulated by both cold and hormone. In grey are TFs regulated by cold but not by hormone. In white are components of hormone signalling pathways, which are not known to be cold-regulated. Arrows and inhibition lines represent activation and suppression processes, respectively. Solid lines indicate a direct interaction; dotted lines represent indirect interactions
