Reversible Burst of Transcriptional Changes during Induction of Crassulacean Acid Metabolism in Talinum triangulare.
Drought tolerance is a key factor for agriculture in the 21st century as it is a major determinant of plant survival in natural ecosystems as well as crop productivity. Plants have evolved a range of mechanisms to cope with drought, including a specialized type of photosynthesis termed Crassulacean acid metabolism (CAM). CAM is associated with stomatal closure during the day as atmospheric CO2 ...
متن کاملCrassulacean Acid Metabolism
Crassulacean acid metabolism (CAM) is a CO2 acquisition, CO2 transient storage and CO2 concentrating mechanism based on organic acid synthesis. CO2 acquisition occurs in the dark. CO2 is fixed and stored in the form of organic acids. Remobilization of CO2 from the organic acids occurs in the light and leads to massive CO2 concentration inside photosynthesizing plant organs (green leaves or stem...
متن کاملMolluscicidal Effects of Talinum triangulare on Bulinus truncatus
The molluscicidal effects of Talinum triangulare from two locations in Nigeria on Bulinus truncatus were studied in the laboratory. Snails were exposed for 96h to different concentrations of ethanolic extract of the plant root from Nsukka in Enugu State and Erei in Cross River State, Nigeria. Those in dechlorinated water served as control. On coming in contact with the test medium, the snails r...
متن کاملCrassulacean acid metabolism: plastic, fantastic.
The occurrence, activity and plasticity of the CAM pathway is described from an introductory viewpoint, framed by the use of the four "Phases" of CAM as comparative indicators of the interplay between environmental constraints and internal molecular and biochemical regulation. Having described a number of "rules" which seem to govern the CAM cycle and apply uniformly to most species, a number o...
متن کاملUpdate on Crassulacean Acid Metabolism Crassulacean Acid Metabolism. A Plastic Photosynthetic Adaptation to Arid Environments
Crassulacean acid metabolism (CAM) is an important elaboration of photosynthetic carbon fixation that allows chloroplast-containing cells to fix CO2 initially at night using phosphoenolpyruvate carboxylase (PEPC) in the cytosol. This leads to the formation of C4 organic acids (usually malate), which are stored in the vacuole. Subsequent daytime decarboxylation of these organic acids behind clos...
