Phosphorylation of Phosphoenolpyruvate Carboxylase Is Essential for Maximal and Sustained Dark CO2 Fixation and Core Circadian Clock Operation in the Obligate Crassulacean Acid Metabolism Species Kalanchoe fedtschenkoi [PDF]

open access: yes, 2017
Phosphoenolpyruvate carboxylase (PPC; EC 4.1.1.31) catalyzes primary nocturnal CO2 fixation in Crassulacean acid metabolism (CAM) species. CAM PPC is regulated posttranslationally by a circadian clock-controlled protein kinase called phosphoenolpyruvate ...

Synchronization of metabolic processes in plants with Crassulacean acid metabolism [PDF]

open access: yesJournal of Experimental Botany, 2004
In plants with Crassulacean acid metabolism, a diel separation of carboxylation processes mediated by phosphoenolpyruvate carboxylase (PEPC) and Rubisco optimizes photosynthetic performance and carbon gain in potentially limiting environments. This review considers the mechanisms that synchronize the supply and demand for carbon whilst maintaining ...

Stomatal Responses to Light, CO2, and Mesophyll Tissue in Vicia faba and Kalanchoë fedtschenkoi

open access: yesFrontiers in Plant Science, 2021
The responses of stomatal aperture to light intensity and CO2 concentration were studied in both Vicia faba (C3) and Kalanchoë fedtschenkoi (Crassulacean acid metabolism; CAM), in material sampled from both light and dark periods.

The ins and outs of CO2 [PDF]

open access: yes, 2015
© 2015 The Author 2015. Published by Oxford University Press on behalf of the Society for Experimental Biology. It is difficult to distinguish influx and efflux of inorganic C in photosynthesizing tissues; this article examines what is known and where ...

Crassulacean acid metabolism in the Basellaceae (Caryophyllales)

open access: yesPlant Biology, 2018
Abstract C4 and crassulacean acid metabolism (CAM) have evolved in the order Caryophyllales many times but neither C4 nor CAM have been recorded for the Basellaceae, a small family in the CAM‐rich sub‐order Portulacineae. 24 h gas exchange and day–night changes in titratable acidity were measured in leaves of Anredera baselloides exposed to wet–dry ...

Phosphoenolpyruvate carboxykinase, pyruvate orthophosphate dikinase and isocitrate lyase in both tomato fruits and leaves, and in the flesh of peach and some other fruits [PDF]

open access: yes, 2016
In this study the occurrence of a number of enzymes involved in gluconeogenesis was investigated in both tomato fruits and leaves during their development and senescence and in some other fruits. The enzymes studied were phosphoenolpyruvate carboxykinase

Ecophysiology of Crassulacean Acid Metabolism (CAM) [PDF]

open access: yesAnnals of Botany, 2004
Crassulacean Acid Metabolism (CAM) as an ecophysiological modification of photosynthetic carbon acquisition has been reviewed extensively before. Cell biology, enzymology and the flow of carbon along various pathways and through various cellular compartments have been well documented and discussed.

Orchestration of carbohydrate processing for crassulacean acid metabolism [PDF]

open access: yesCurrent Opinion in Plant Biology, 2016
The production of phosphoenolpyruvate as a substrate for nocturnal CO2 uptake represents a significant sink for carbohydrate in CAM plants which has to be balanced with the provisioning of carbohydrate for growth and maintenance. In starch-storing CAM species, diversification in chloroplast metabolite transporters, and the deployment of both ...

The Epiphytic Fern Elaphoglossum luridum (Fée) Christ. (Dryopteridaceae) from Central and South America: Morphological and Physiological Responses to Water Stress

open access: yesThe Scientific World Journal, 2014
Elaphoglossum luridum (Fée) Christ. (Dryopteridaceae) is an epiphytic fern of the Atlantic Forest (Brazil). Anatomical and physiological studies were conducted to understand how this plant responds to water stress. The E.

Photosynthetic primary production in the Mesoproterozoic

open access: yesNew Phytologist, EarlyView.
Summary The Mesoproterozoic atmosphere had more CO2 and less O2 than at present. While the upper ocean was oxygenated, the deeper ocean was euxinic or ferruginous. Primary production was performed by Chlorobia, Cyanobacteria, Proteobacteria, and Archaeplastida.
