AB  - Light signals regulate a plethora of plant responses throughout their life cycle, 
      especially the red and far-red regions of the light spectrum perceived by the 
      phytochrome family of photoreceptors. However, the mechanisms by which 
      phytochromes regulate gene expression and downstream responses remain elusive. 
      Several recent studies have unraveled the details on how phytochromes regulate 
      photomorphogenesis. These include the identification of E3 ligases that degrade 
      PHYTOCHROME INTERACTING FACTOR (PIF) proteins, key negative regulators, in 
      response to light, a better view of how phytochromes inhibit another key negative 
      regulator, CONSTITUTIVELY PHOTOMORPHOGENIC 1 (COP1), and an understanding of why 
      plants evolved multiple negative regulators to repress photomorphogenesis in 
      darkness. These advances will surely fuel future research on many unanswered 
      questions that have intrigued plant photobiologists for decades.
