In Arabidopsis, phot1 mutants have a normal avoidance response and a poor accumulation response, phot2 mutants lack the avoidance response but retain a fairly normal accumulation response, while phot1/phot2 double mutant lack both the avoidance and accumulation responses. These results indicate that,

#Unit 6. System Physiology – Plant
  1. Phot1 plays a key role in the avoidance response, and that both phot1 and phot2 contribute to the accumulation response
  2. Phot2 plays a key role in the avoidance response, and that both phot1 and phot2 contribute to the accumulation response
  3. Phot2 plays a key role in the accumulation response, and that both phot1 and phot2 contribute to the accumulation response as well as in avoidance response 
  4. phot1 mutants in fact do not survive in the field under conditions of full sunlight due to photooxidative damage
