AB  - Constitutively photomorphogenic 1 (COP1) is an E3 ubiquitin ligase that has been 
      studied extensively in the photomorphogenesis- and light-related processes in 
      Arabidopsis. However, the possible role of COP1 in plant drought stress response 
      remains unknown. Hence, in the present study, the stomatal behavior as one of the 
      key elements in plant dehydration response was investigated in Arabidopsis cop1-4 
      and pea light-independent photomorphogenesis (lip1) mutants. We observed that 
      water loss rate in the cop1-4 and lip1 detached leaves was significantly much 
      faster than wild-type, resulting from failing to reduce the stomatal aperture by 
      the mutants. But, interestingly, the cop1-4 and lip1 isolated leaves treated with 
      abscisic acid (ABA) as well as cop1-4 and lip1 soil-grown under drought stress 
      could close their stomata as wild-type. Hence, COP1 plays a fundamental role in 
      the regulation of stomatal movements in response to dehydration and its function 
      was conserved during evolution in both Arabidopsis and pea. Further evaluations 
      showed the cop1-4 mutant was not significantly damaged from the oxidative stress 
      derived from soil water limiting conditions when compared to wild-type. 
      Similarly, the up-regulation level of several key stress-responsive genes was 
      relatively lower in cop1-4 than wild-type. Therefore, COP1 might be considered as 
      a potential key regulator of both short-and long-term dehydration response. 
      Multiple stress-related cis-elements were also detected in the COP1 promoter 
      region, which supported its up-regulation in response to drought, salt, and cold 
      stresses. Besides, we figured out the constitutively open stomata of cop1-4 in 
      darkness can be as a result of the reduced AtMYB61 expression.
