Characeae Biomass: Is the Subject Exhausted?
Popularly known as stoneworts, brittleworts, muskgrass, muskworts or bass-weeds, Characeae are among the largest and most complex green algae. All common names come from some characteristics these plants may exhibit, such as the brittle, limestone (calcium carbonate) exoskeleton that can form on the external surfaces of the plant (e.g. Chara vulgaris and Chara globularis) and, particularly, fro...
متن کاملIonic mechanism of mechano-perception in Characeae.
Characean internodal cells generate receptor potential in response to mechanical stimuli. We studied responses of internodal cells to a long-lasting stimulus and the results were as follows. (i) The cell generated receptor potential at the moment of both compression and decompression. (ii) The receptor potential (DeltaE (m)) was significantly larger at the moment of decompression than at compre...
متن کاملSalt tolerance at single cell level in giant-celled Characeae
Characean plants provide an excellent experimental system for electrophysiology and physiology due to: (i) very large cell size, (ii) position on phylogenetic tree near the origin of land plants and (iii) continuous spectrum from very salt sensitive to very salt tolerant species. A range of experimental techniques is described, some unique to characean plants. Application of these methods provi...

15 صفحه اولExogenous melatonin affects photosynthesis in characeae Chara australis
Melatonin was found in the fresh water characeae Chara australis. The concentrations (~4 μg/g of tissue) were similar in photosynthesizing cells, independent of their position on the plant and rhizoids (roots) without chloroplasts. Exogenous melatonin, added at 10 μM to the artificial pond water, increased quantum yield of photochemistry of photosystem II by 34%. The increased efficiency appear...
