Which of the following given statements about PHYA is incorrect?

#Unit 6. System Physiology – Plant
  1. PhyA mediates very few responses because they are highly regulated at transcriptional and translational level
  2. PHYA gene is transcriptionally active in dark-grown seedlings, but its expression is strongly inhibited in the light in monocots
  3. The amount of phyA in the cell is also regulated by protein destruction
  4. In presence of light stabilization of PHYA expression
