The nematocyst extract of Hydra attenuata causes single channel events in lipid bilayers.
The nematocyst extract of Hydra attenuata causes single conductance events in reconstituted planar lipid membranes as well as in inside-out patches derived from liposomes. The smallest single channel conductance level of the toxins is 110 pS. The conductance levels increase stepwise with time up to 2000 pS. These large conductance jumps indicate channel cooperativity. If the membrane-voltage is...
متن کاملGenetic analysis of developmental mechanisms in Hydra. IV. Characterization of a nematocyst-deficient strain.
The authors have previously found that mutant hydra strains showing various types of developmental defects can be isolated through sexual inbreeding of wild hydra. One such defective strain, called nem-4, contains virtually no stenoteles, one of the four types of nematocysts present in hydra, in its tentacles. However, stenoteles are present at a normal level in the body column of this strain, ...
متن کاملHydra
What is Hydra? Hydra is a member of the animal phylum Cnidaria. This phylum includes corals, sea anemones and jellyfish. While most cnidarians are marine, Hydra is unusual in that it lives exclusively in fresh water. Hydra was first described by Antoni van Leeuwenhoek (1632– 1723) in a letter he sent to the Royal Society on Christmas day, 1702. The letter included a red chalk drawing of Hydra o...
متن کاملNanosecond-scale kinetics of nematocyst discharge
dispersed genes in different lineages. First, the cluster may have been broken up in organisms with elevated rates of genome evolution, such as C. intestinalis, C. elegans and Drosophila melanogaster. This implies that cluster integrity in other lineages may not be due to selection. Conversely, clusters may have been maintained in some lineages due to selection. This would imply a relaxation of...
متن کاملMeasuring glutathione-induced feeding response in hydra.
Hydra is among the most primitive organisms possessing a nervous system and chemosensation for detecting reduced glutathione (GSH) for capturing the prey. The movement of prey organisms causes mechanosensory discharge of the stinging cells called nematocysts from hydra, which are inserted into the prey. The feeding response in hydra, which includes curling of the tentacles to bring the prey tow...
