MeSH Heading: Crassulacean Acid Metabolism
Tree Number(s): G02.111.158.937.350; G02.111.669.700.350; G02.740.921.500; G03.191.937.350; G03.493.700.500; G03.800.700.350; G15.568.500
Unique ID: D000081962
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D000081962
Scope Note: A water-saving mode of photosynthesis whereby CARBON DIOXIDE (CO2) taken up during the nocturnal opening of stomata (STOMATA, PLANT) is fixed to produce malate, which is accumulated in VACUOLES overnight as malic acid and subsequently decarboxylated during the day with the resulting CO2 produced being re-fixed by RUBISCO and re-assimilated through the REDUCTIVE PENTOSE PHOSPHATE CYCLE. CAM photosynthesis is found mostly in plants in arid areas, but it is also found in aquatic plants and orchids.
