CRASSULACEAN ACID METABOLISM:Molecular Genetics

Annual Review of Plant Physiology and Plant Molecular Biology, 1999
▪ Abstract  Crassulacean acid metabolism (CAM) is an adaptation of photosynthesis to limited availability of water or CO2. CAM is characterized by nocturnal CO2fixation via the cytosolic enzyme PEP carboxylase (PEPC), formation of PEP by glycolysis, malic acid accumulation in the vacuole, daytime decarboxylation of malate and CO2re-assimilation via ...

Crassulacean acid metabolism in Sedum dasyphyllum L.

Plant Biosystems - An International Journal Dealing with all Aspects of Plant Biology, 1999
Abstract Crassulacean Acid Metabolism (CAM) in Sedum dasyphyllum L. (Crassulaceae) was analysed by studying four ecotypes collected in sites at different altitudes in the Campania region (Italy), and grown in well‐watered conditions at the Botanical Garden of Naples.

The Evolution of Crassulacean Acid Metabolism

1996
This paper takes a wide view of the evolution of CAM; in particular it addresses the question why CAM does what it does and why other CAM-like possibilities have not been used.

Cell organelles from crassulacean acid metabolism (CAM) plants

Planta, 1980
The intracellular distribution of enzymes involved in the Crassulacean acid metabolism (CAM) has been studied in Bryophyllum calycinum Salisb. and Crassula lycopodioides Lam. After separation of cell organelles by isopycnic centrifugation, enzymes of the Crassulacean acid metabolism were found in the following cell fractions: Phosphoenolpyruvate ...

Use of infrared thermography for monitoring crassulacean acid metabolism

Functional Plant Biology, 2016
Crassulacean acid metabolism (CAM) is an alternative carbon fixation pathway that imparts high water-use efficiency in plants adapted to warm, semiarid climates. With concerns that global warming will negatively influence crop production, turning agricultural focus towards CAM plants may provide a solution to increase productivity using either ...

Cryptic crassulacean acid metabolism (CAM) in Jatropha curcas

Functional Plant Biology, 2015
Jatropha curcas L. is a drought-tolerant shrub or small tree that is a candidate bioenergy feedstock. It is a member of the family Euphorbiaceae in which both CAM and C4 photosynthesis have evolved. Here, we report that J. curcas exhibits features diagnostic of low-level CAM.

A Model for Photosynthetic Oscillations in Crassulacean Acid Metabolism (CAM)

Journal of Theoretical Biology, 1997
We propose a model of crassulacean acid metabolism (CAM) describing the varying concentrations of pools of major metabolites by a system of coupled nonlinear differential equations. The model shows regular oscillations in normal day night and free-running endogeneous oscillations in continuous light.

Ecophysiology of Plants with Crassulacean Acid Metabolism

2000
The taxonomic and ecological diversity of CAM plants is testament to a suite of morphological and metabolic attributes. These have evolved under contrasting selective pressures in up to 7% of all plant species many times over the past 10–100 Ma. The water and carbon conserving features of CAM impose: i) morphological constraints in terms of the ...

Functional leaf anatomy of plants with crassulacean acid metabolism

Functional Plant Biology, 2005
Crassulacean acid metabolism (CAM) has evolved independently on dozens of occasions and is now found in over 7% of plant species. In this study, 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 ...

Enzymes of Crassulacean Acid Metabolism

1979
Crassulacean acid metabolism (CAM), whose general features have been discussed by Kluge in Chapter II.8, requires the interaction of several groups of enzymes during alternate periods of the diurnal cycle of light and darkness. These enzymes, which must be subject to a sophisticated mode of regulation in order to bypass undesired competition, are the ...
