AB  - Crassulacean acid metabolism (CAM) is an adaptation of photosynthesis to limited 
      availability of water or CO2. CAM is characterized by nocturnal CO2 fixation via 
      the cytosolic enzyme PEP carboxylase (PEPC), formation of PEP by glycolysis, 
      malic acid accumulation in the vacuole, daytime decarboxylation of malate and CO2 
      re-assimilation via ribulose-1,5-bisphosphate carboxylase (RUBISCO), and 
      regeneration of storage carbohydrates from pyruvate and/or PEP by 
      gluconeogenesis. Within this basic framework, the pathway exhibits an 
      extraordinary range of metabolic plasticity governed by environmental, 
      developmental, tissue-specific, hormonal, and circadian cues. Characterization of 
      genes encoding key CAM enzymes has shown that a combination of transcriptional, 
      posttranscriptional, translational, and posttranslational regulatory events 
      govern the expression of the pathway. Recently, this information has improved our 
      ability to dissect the regulatory and signaling events that mediate the 
      expression and operation of the pathway. Molecular analysis and sequence 
      information have also provided new ways of assessing the evolutionary origins of 
      CAM. Genetic and physiological analysis of transgenic plants currently under 
      development will improve our further understanding of the molecular genetics of 
      CAM.
