The plant family Portulacaceae is a relatively small family (∼19 genera and ∼425 species) with a widespread distribution. Species of the Portulacaceae range in size from small herbaceous plants to shrubs that measure up to 4 m in height. Most members of the family have leaves that range from fleshy to fully succulent and live in very diverse habitats ranging from shady understory plants to plants exposed to full sunlight. The Portulacaceae have members that utilize different photosynthetic… 
A phylogenetic view of low-level CAM in Pelargonium (Geraniaceae).
A survey for CAM across Pelargonium is presented, emphasizing theWinter rainfall clade, predominantly from the winter rainfall region of southern Africa, likely proliferated in response to Miocene or Pliocene aridification.
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.
Does the C4 plant Trianthema portulacastrum (Aizoaceae) exhibit weakly expressed crassulacean acid metabolism (CAM)?
Trianthema becomes the second genus of vascular land plants in which C4 and features of CAM have been demonstrated to co-occur in the same plant and the first C4 plant with CAM-type acidification described for the Aizoaceae.
Evolutionary physiology: the extent of C4 and CAM photosynthesis in the genera Anacampseros and Grahamia of the Portulacaceae.
The Portulacaceae is one of the few terrestrial plant families known to have both C(4) and Crassulacean acid metabolism (CAM) species. There may be multiple origins of the evolution of CAM within the
Concerted anatomical change associated with crassulacean acid metabolism in the Bromeliaceae.
Overall, leaf anatomy is clearly and strongly coupled with the photosynthetic pathway in the Bromeliaceae, where the independent origins of CAM have involved significant anatomical restructuring.
Low-level CAM photosynthesis in a succulent-leaved member of the Urticaceae, Pilea peperomioides.
This is the first report of CAM in the family Urticaceae and nocturnal increases in titratable acidity in both leaf laminas and petioles were observed in all plants exposed to wet-dry-wet cycles, providing unequivocal evidence of CAM activity.
Photosynthetic and anatomical characteristics in the C4crassulacean acid metabolism-cycling plant Portulaca grandiflora.
Results demonstrate, for the first time, that the stem of P. grandiflora is an inducible CAM-idling tissue, and indicate that the C4 and CAM pathways operate independently of one another in P.grandiflorA.
Evolution of leaf anatomy and photosynthetic pathways in Portulacaceae.
The diversity of leaf anatomical types and C4 biochemical variants suggest multiple independent origins of C4 photosynthesis, and evidence for a switch from C4 to C3-C4 intermediacy supports the hypothesis that intermediates represent a distinct successful strategy.
Crassulacean acid metabolism in the Basellaceae (Caryophyllales).
The reversible induction of nocturnal net CO2 uptake by drought stress indicates that Anredera baselloides is able to exhibit C4 and crassulacean acid metabolism in a facultative manner, the first report of CAM in a member of the Basellaceae.


Crassulacean Acid Metabolism in Three Species of the C4 Genus Portulaca
This study confirms past reports of CAM acid fluctuations in P. grandiflora and P. oleracea and marks the first report of CAM activity in P., which is found on rock outcrops throughout the southwestern United States.
Carbon metabolism in two species of pereskia (cactaceae).
Water stress causes these cacti to shift to an internal CO(2) recycling ("idling") that has all attributes of Crassulacean acid metabolism except nocturnal stomata opening and CO(3) uptake.
Crassulacean Acid Metabolism
Plants with crassulacean acid metabolism (CAM) are rarely the most abundant in plant communities, and rarely attain high biomass, but they are capable of an extraordinary array of physiological
Characteristics of Crassulacean Acid Metabolism in the Succulent C(4) Dicot, Portulaca oleracea L.
Results indicate that under certain conditions, such as water stress or short photoperiods, P. oleracea is capable of developing an acid metabolism with many similarities to CAM.
Occurrence of Inducible Crassulacean Acid Metabolism in Leaves of Talimum triangulare (Portulacaceae)
CAM seems to be important for the tolerance of plants of this species to moderately prolonged periods of drought in conditions of full exposure as well as shade, and also for regaining high photosynthetic rates shortly after irrigation.
Structural aspects of the leaves of seven species of Portulaca growing in Hawaii
Seven species of Portulaca growing in Hawaii can be divided into two groups based on the morphology, anatomy, and ultrastructure of their leaves. Portulaca oleracea, P. molokiniensis, P. lutea,
Seasonal patterns of water relations and enzyme activity of the facultative CAM plant Portulacaria afra (L.) Jacq.
The results support the hypothesis that the induction of CAM occurred due to low transient water potentials and may be partially mediated through the loss of turgor and lead to an increase in water use efficiency during such periods when compared to other inducible CAM species.
Induction of Acid Metabolism in Portulacaria afra.
Stressed plants showed only dark CO(2) uptake and dark water loss, nocturnal stomatal opening, and an increased diurnal fluctuation of titratable acidity indicating that the response to stress was reversible.
Crassulacean Acid Metabolism in the Succulent C(4) Dicot, Portulaca oleracea L Under Natural Environmental Conditions.
Results substantiate earlier work with growth-chamber-grown plants and show that limited CAM activity can occur in the succulent C(4) dicot Portulaca oleracea L. Oleracea under certain natural environmental conditions.
