Hydrogen, Oxygen, and Carbon Isotope Ratios of Cellulose from Submerged Aquatic Crassulacean Acid Metabolism and Non-Crassulacean Acid Metabolism Plants

, 1984
Isotope ratios of cellulose and cellulose nitrate from aquatic Crassulacean acid metabolism (CAM) and non-CAM plants were determined. Cellulose oxygen istope ratios for all plants that grew together were virtually identical, whereas large differences ...

Dental enamel hypoplasia and intra‐tooth isotope records as indicators of physiological stress and environmental variability in Early Pleistocene hippopotamids from Melka Kunture (Upper Awash, Ethiopia)

Journal of Quaternary Science, EarlyView.
ABSTRACT Enamel hypoplasia results from temporary disruptions of enamel deposition during tooth development. It is widely used as an indicator of physiological stress in archeological and paleontological contexts; yet, its relationship with environmental conditions during tooth formation remains poorly constrained.

Altered Gene Regulatory Networks Are Associated With the Transition From C3 to Crassulacean Acid Metabolism in Erycina (Oncidiinae: Orchidaceae)

Frontiers in Plant Science, 2019
Crassulacean acid metabolism (CAM) photosynthesis is a modification of the core C3 photosynthetic pathway that improves the ability of plants to assimilate carbon in water-limited environments. CAM plants fix CO2 mostly at night, when transpiration rates

Nutritional properties, traditional uses and potential new applications for the sotol plant (Asparagaceae, Convallarioideae): A review

PLANTS, PEOPLE, PLANET, EarlyView.
Sotol (Dasylirion spp.) is a resilient desert plant that sustains ecosystems, cultures and livelihoods in Chihuahua Desert. Our review highlights its nutritional properties, traditional uses and potential new applications in food, pharmaceuticals, renewable energy and water remediation. By synthesizing evidence across disciplines, we show how sotol can

Diel rewiring and positive selection of ancient plant proteins enabled evolution of CAM photosynthesis in Agave

BMC Genomics, 2018
Background Crassulacean acid metabolism (CAM) enhances plant water-use efficiency through an inverse day/night pattern of stomatal closure/opening that facilitates nocturnal CO2 uptake.

Spatial Patterns of Avian Stable Isotopes Reveal Ecological Impacts of Climate and Land‐Use Change

Integrative Zoology, EarlyView.
Increased feather δ15N values with pasture coverage reveal an elevated baseline δ15N in grazing landscapes, while broader isotopic niches in farmland habitats reflect agricultural expansion's significant influence on resource use patterns of the avian community.

Diversity of CAM plant photosynthesis (crassulacean acid metabolism): a tribute to Barry Osmond [PDF]

Functional Plant Biology, 2021
This special issue is a tribute to the Australian plant biologist Professor Charles Barry Osmond – Fellow of the Australian Academy of Sciences, the Royal Society of London, and Leopoldina, the German National Academy of Sciences – and his many contributions to our understanding of the biochemistry and physiological ecology of CAM (crassulacean acid ...

Photo-Protective Mechanisms and the Role of Poly (ADP-Ribose) Polymerase Activity in a Facultative CAM Plant Exposed to Long-Term Water Deprivation

Plants, 2020
The Crassulacean acid metabolism (CAM) pathway helps plants to alleviate the oxidative stress under drought, but the shift to CAM-idling may expose plants to the overproduction of reactive oxygen species causing cell damages.
