A list of plant species documented over the past 25 years to exhibit Crassulacean Acid Metabolism (CAM) is presented. The list compiles all available information on these species including their growth habits, succulent parts, carbon isotope discrimination values, CAM types, CAM inducers, and CAM modifications. 
Crassulacean acid metabolism-cycling in Euphorbia milii
The occurrence of CAM-cycling is shown to serve as a mechanism of water conservation and a detailed report of such CAM mode in the genus, which is abundant in constitutive CAM and C4 species.
CAM is widely distributed among botanical families, its origin is believed to be polyphyletic; however, the evolutionary mechanisms which allowed reappearance of this complex metabolism are not yet understood.
INVITED REVIEW Ecophysiology of Crassulacean Acid Metabolism (CAM)
The present attempt at reviewing CAM once again tries to use a different approach, considering a wide range of inputs, receivers and outputs.
Functional leaf anatomy of plants with crassulacean acid metabolism.
The leaf structure of a phylogenetically diverse assemblage of 18 CAM plants was compared with six C3 plants and four C4 plants to assess whether consistent anatomical patterns that may reflect functional constraints are present.

Examination of quantitative census data for CAM diversity and biomass suggests that the larger CAM domains are those systems which are governed by a network of interacting stress factors requiring versatile responses and not systems where a single stress factor strongly prevails.
The occurrence of crassulacean acid metabolism in Cymbidium (Orchidaceae) and its ecological and evolutionary implications
The evolution of strong CAM likely enabled Cymbidium to extend to exposed sites in tropical lowland where marked water stress exists and such potential plasticity of CAM may realize the radiation of Cymbium into sites with different environmental conditions.
Crassulacean Acid Metabolism and Survival of Asexual Propagules of Sedum wrightii
In Sedum wrightii grown in a growth chamber, detached leaves could survive for at least 120 d with a high rate of success for propagule formation. The pattern of gas exchange, associated with CAM,
Crassulacean Acid Metabolism Permutation and Survival of Caralluma Species (Apocynaceae) in Arid Habitats
Investigations showed that these three Caralluma species were obligate CAM plants exhibiting this mode of photosynthesis during both the wet and the dry seasons, and under protracted water stress during the long dry season very low values of stomatal diffusive conductance and dampening of CAM acidification-deacidification cycles denoted the tendency of these three species to shift from the obligating CAM physiotype to CAM-idling mode.
Temperature determines the occurrence of CAM or C3 photosynthesis in pineapple plantlets grown in vitro
A role for temperature in determining the type of carbon fixation pathway in in vitro grown pineapple plants is clearly indicated, and evidence that ABA and IAA participate in CAM signaling is provided.

Taxonomic distribution of crassulacean acid metabolism
The list presented in Table 26.1 summarizes the available information on the taxonomic occurrence of the CAM pathway. Details of the methods used to detect CAM activity can be found in the original
Evolutionary Aspects of Crassulacean Acid Metabolism in the Crassulaceae
The CAM pathway is taxonomically widespread and is believed to be used by about 16 000 species of vascular plants (see p. 9), a figure that includes more than 6% of all angiosperms. In addition, CAM
Crassulacean acid metabolism : biochemistry, ecophysiology, and evolution
New areas of research reviewed in detail in this book include regulation of gene expression and the molecular basis of CAM, the ecophysiology of CAM plants from tropical environments, the productivity of agronomically important cacti and agaves, the ecology of CAM in submerged aquatic plants, and the taxonomic diversity and evolutionary origins of CAM.
CAM: Regulated Photosynthetic Metabolism for all Seasons
The essence of crassulacean acid metabolism (CAM) as reviewed by Osmond and Holturn (1981), Ting and Gibbs (1982), and its relationship to C3 and C4 photosynthesis can be summarised as shown
Crassulacean Acid Metabolism in Submerged Aquatic Plants
The evidence of CAM in Isoetes howellii, the data on the distribution of CAMIn aquatic species, and the work to date on the functional significance of Cam in aquatic species are summarized.
Crassulacean Acid Metabolism in Leaves and Stems of Cissus quadrangularis
It is suggested that CAM is a widespread feature in the genus Cissus that might have facilitated the spread of the genus from the wet into the arid tropics.
Crassulacean acid metabolism in Lithops insularis; a non-halophytic member of the Mesembryanthemaceae
Lithops insularis, a non-halophytic member of the Mesembryanthemaceae, is shown to exhibit major features if crassulacean acid metabolism, and the accumulation of malic acid synthesised in darkness from carbon dioxide is demonstrated.
Altitudinal changes in the incidence of crassulacean acid metabolism in vascular epiphytes and related life forms in Papua New Guinea
The highland epiphytic orchids possessed a greater mean leaf thickness than their lowland C3 counterparts due to the frequent occurrence of water storage tissue located on the adaxial side of the leaf, and it is suggested that low daytime temperatures in the highland microhabitats is a major factor in explaining the absence of CAM.
