The action potential of Dionaea muscipula Ellis
The intention of this investigation was to acquire more concise information about the nature of the action potential of Dionaea muscipula Ellis and the different types of cells generating and… Expand
Gravity sensing in tip-growing cells.
In addition to the statocytes of roots and shoots, a number of tip-growing cells also sense gravity, which influences the cells' growth and development. Since these tip-growing cells are highly… Expand
Tissue stresses in organs of herbaceous plants III. Elastic properties of the tissues of sunflowers hypocotyl and origin of tissue stresses
The finding that there are considerable tissue stresses (TSs) in the hypocotyl of Helianthus annuus L. prompts the question: how are the stresses generated? Here, a one-dimensiona l model is… Expand
ANALYSIS OF EXTENSION AND CURVATURE DURING THE GRAVIRESPONSE IN LEPIDIUM ROOTS
Intact roots of Lepidium sativum were photographed at 1.5to 6-min intervals before and after being tilted from a vertical to a horizontal position. Relative extension rates were calculated for… Expand
The influence of Ca2+ on the action potential in mesophyll cells ofDionaea muscipula Ellis
Ion fluxes during the action potentials of different characean cells are intensively studied revealing complicated fluxes of both C1and Ca 2+ during depolarisation (for review see BEILBY 1984). In… Expand
Morphogenesis and Polarity of Tubular Cells with Tip Growth
Morphogenesis of a plant cell, as treated in this chapter, is, in general, morphogenesis of the cell wall with an emphasis on growth. The reason for this specialized treatment of cell morphogenesis… Expand
Role of the microtubule cytoskeleton in gravisensing Chara rhizoids.
The arrangement of the microtubule cytoskeleton in tip-growing and gravisensing Chara rhizoids has been documented by immunofluorescence microscopy. Predominantly axially oriented undulating bundles… Expand
On the mechanism of trap closure of Venus flytrap (Dionaea muscipula Ellis)
The rapid trap closure of Dionaea muscinula Ellis has been explained by either a loss of turgor pressure of the upper epidermis, which should thus become flexible, or by a sudden acid-induced wall… Expand
Cyclopiazonic acid disturbs the regulation of cytosolic calcium when repetitive action potentials are evoked in Dionaea traps
Evoking of action potentials (APs) in the trap of Dionaea muscipula Ellis at intervals shorter than 20 s caused a gradual decrease in the amplitude of the APs. At longer intervals the amplitude was… Expand
Rapid Changes in the Pattern of Electric Current around the Root Tip of Lepidium sativum L. following Gravistimulation.
Using a highly sensitive vibrating electrode, the pattern of naturally occurring electric currents around 1-day-old primary roots of Lepidium sativum L. growing vertically downward and the current… Expand
