Effects of competition on induction of crassulacean acid metabolism in a facultative CAM plant
Oecologia, 2017Abiotic drivers of environmental stress have been found to induce CAM expression (nocturnal carboxylation) in facultative CAM species such as Mesembryanthemum crystallinum. The role played by biotic factors such as competition with non-CAM species in affecting CAM expression, however, remains largely understudied. This research investigated the effects

Engineering crassulacean acid metabolism to improve water-use efficiency [PDF]
Trends in Plant Science, 2014 Climatic extremes threaten agricultural sustainability worldwide. One approach to increase plant water-use efficiency is to introduce crassulacean acid metabolism (CAM) into C3 crops.

Crassulacean acid metabolism (CAM) in high elevation tropical cactus
Plant, Cell & Environment, 1989Abstract. Several taxa of cacti are distributed in high elevation tropical alpine habitats between 4000–4700 m in central Peru. This region has a marked dry season with soil water potentials as low as – 25 MPa. The barrel type cactus Oroya peruviana and the low ceaspitose Tephrocactus floccosus (both the typical hairy form and a hairless form) all ...

Abstract. The CAM plants Kalanchoe tubiflora and K. blossfeldiana were grown under photoperiodically controlled conditions (short days). In these plants, phos‐phoenolpyruvate carboxylase capacity and the sensitivity of the enzyme to the effectors L‐malate (inhibitor) and glucose‐6‐phosphate (activator) were measured throughout the diurnal CAM cycle. In

Cell organelles from crassulacean-acid-metabolism (CAM) plants
Planta, 1978Cell organelles were isolated from the CAM plants Crassula lycopodioides Lam., Bryophyllum calycinum Salisb. and Sedum rubrotinctum R.T. Clausen by isopycnic centrifugation in sucrose gradients. The inclusion of 2.5% Ficoll in the grinding medium proved to be essential for a satisfactory separation of cell organelles during the subsequent ...

Crassulacean acid metabolism (CAM) in leaves of Aloe arborescens mill
Planta, 1979In the succulent leaves of Aloe arborescens Mill diurnal oscillations of the malic acid content, being indicative of Crassulacean Acid Metabolism (CAM), were exhibited only by the green mesophyll. In contrast, the malic acid level of the central chloroplast-free water-storing tissue remained constant throughout the day-night cycle.

The Flow of Carbon in Crassulacean Acid Metabolism (CAM)
1979It is now generally accepted that the Crassulacean Acid Metabolism (CAM) may be interpreted as a variant of the photosynthetic CO2 fixation. CAM is performed mainly but not exclusively by succulents of the Crassulacean family (Black and Williams, 1976; Szarek and Ting, 1977; Kluge and Ting, 1978).

Past studies have largely focused on hydraulic redistribution (HR) in trees, shrubs, and grasses, and recognized its role in interspecies interactions. HR in plants that conduct crassulacean acid metabolism (CAM), however, remains poorly investigated, as does the effect of HR on transpiration in different vegetation associations (i.e., tree-grass, CAM ...

Seasonal changes in the Crassulacean Acid Metabolism (CAM) activity and growth characteristics of Opuntia humifusa Raf. were examined under midwest climatic conditions. Twenty-four hour studies were done at monthly intervals for two years, with diurnal changes in transpiration, gas exchange, and titratable acidity monitored under natural conditions ...

This study demonstrates unequivocally the presence of crassulacean acid metabolism (CAM) in a species of the Rubiaceae, the fourth largest angiosperm plant family. The tropical Australian endemic epiphytic ant-plant, Myrmecodia beccarii Hook.f., exhibits net CO(2) uptake in the dark and a concomitant accumulation of titratable acidity in plants in the ...
