The ability of some species of the genus Senecio to perform Crassulacean acid metabolism (CAM) in plants growing both under controlled conditions and outdoors and the anatomy of their photosynthesizing organs, leaves, and/or stems were investigated. The studied species differed in leaf morphology and in degrees of leaf and stem succulence. Malate accumulation differed with environmental conditions. The carbon isotope ratio δ13C indicated that, in most of the species, the C3 carboxylation… 
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.
Crassulacean acid metabolism in Sedum dasyphyllum L.
During the growth season, from winter to late spring, the overall malate content at dusk and at dawn declined strongly, thus showing a negative correlation with photoperiod, and the specific activity of the enzymes involved in CAM showed a seasonal pattern with a significant increase for phosphoenolpyruvate carboxylase, but a decrease for NAD‐dependent malate dehydrogenase and NADP‐ dependent malic enzyme.
The Influence of Leaf "Windows" on Crassulacean Acid Metabolism in the South African Succulent Senecio Rowleyanus (Asteraceae)
Net CO2 exchange rate (PN) of shoots and diel fluctuations in titratable acidity of leaves of Senecio rowleyanus were measured to determine whether penetration of radiant energy through leaf
Morpho-anatomical changes and photosynthetic metabolism of Stenocereus beneckei seedlings under soil water deficit.
In this study, photosynthetic metabolism (titratable protons) and morpho-anatomical features of Stenocereus beneckei seedlings were examined under limiting water conditions and it seems that soil moisture does not determine CAM expression.
Are thick leaves, large mesophyll cells and small intercellular air spaces requisites for CAM?

Neither leaf thickness nor mesophyll traits helped explain the degree of CAM expression, and an influence of phylogeny on leaf anatomy was evidenced in a few cases but this precluded generalization for widely separate taxa containing CAM species.
Diel patterns of CO2 exchange for epiphytic cacti differing in succulence.
For 6 species of epiphytic cacti examined, increased reliance on nocturnal CO, uptake characteristic of Crassulacean acid metabolism (CAM) was closely correlated with increases in stem thickness, fresh weight per unit area, water mass per unit Area, and to a somewhat lesser extent with another measure of succulence, watermass per unit mass of chlorophyll.
Comparative Morphology and Anatomy of the Stem of the Flowering Plants
With few exceptions, this discussion is restricted to literature published in the years 1986–1990 which has been responsible for the formation of new morphological concepts as well as the reinforcement, substantial modification, or even abandonment of existing theories on the nature, structure, origin, and evolution of angiosperm stems and tissues.
Photosynthetic electron transport rate (ETR) in the littoral herb Launaea sarmentosa known as mole crab in Thailand
Green shade cloth has no effect on total daily photosynthetic electron transport of Launaea but offers some protection from desiccation and excessive evapotranspiration, and waterlogging decreases ETR by about 40%.


Variability in Crassulacean Acid Metabolism: A Survey of North Carolina Succulent Species
The correlation between succulence and Crassulacean acid metabolism was investigated in 28 succulent species growing in various habitats throughout North Carolina, emphasizing that one photosynthetic pathway does not characterize all succulents in North Carolina.
Environmental Influences on CAM Activity of Cissus quadrangularis
Data indicate that under natural conditions CAM should effectively contribute to the successful adaptation of C. quadrangularis to its environment.
Effects of photoperiod and ageing on the carbon isotope composition of Bryophyllum daigremontianum Berger
Changes in crassulacean acid metabolism in the leaves of Bryophyllum daigremontianum were studied comparatively under closely controlled and semi-natural conditions utilizing measurements of natural carbon isotope composition (δ13C) of the total leaf matter.
CAM, Transpiration, and Adaptive Mechanisms to Xeric Environments in the Succulent Cucurbitaceae
Outdoor experiments demonstrated very low daily transpiration rates, relatively large nocturnal water loss, and malate accumulation, that is, the occurrence of crassulacean acid metabolism, which constitutes a high degree of physiological adaptation to drought.
Nocturnal Accumulation of Acid in Leaves of Wall Pennywort (Umbilicus rupestris) Following Exposure to Water Stress
Physiological responses to water stress (drought) have been investigated in Umbilicus rupestris by comparing control and draughted plants with respect to diurnal fluctuations in the acid content of the leaves, CO2 exchange patterns and stomatal conductance, and a clear CAM-type pattern is observed.
CAM activity and day/night changes in the ultrastructure of stem chlorenchyma of Cissus quadrangularis L. as influenced by drought
The maintenance of the cellular integrity accounts for the ability of C. quadrangularis to recover rapidly from water stress, and the increase in chlorophyll coment was higher in stressed plants.
Transpiration in Succulent Plants
F. FROMME examines the cells of the central arch of the peridium of Peridermium Pini and finds that the apical cells ofthe central spore chains that have, before their metamorphosis into peridial cells, cut off intercalary cells below are morphologically aeciospores.
Crassulacean Acid Metabolism: Analysis of an Ecological Adaptation
This chapter discusses the taxonomy and Geographical Distribution of CAM plants, Morphology, Anatomy, and Ultrastructure of CAM Plants, and Metabolic Control of CAM.

The extraction of chlorophylls in higher plant tissue using N,N-dimethylformamide expedites the process and enables the determination of small samples with low pigment level, and formulae for quantitative determination of pigments concentrations were developed.
