Ca2+ and nucleotide dependent regulation of voltage dependent anion channels in the plasma membrane of guard cells.

• Rainer Hedrich, Hauke Busch, Klaus Raschke
• The EMBO journal
• 1990

Using the patch-clamp technique we discovered that the voltage dependent anion channels in the plasma membrane of guard cells are activated by a rise in cytoplasmic Ca2+ in the presence of… (More)

Voltage dependence of K channels in guard-cell protoplasts.

• Julian I Schroeder, Klaus Raschke, Erhard Neher
• Proceedings of the National Academy of Sciences…
• 1987

Stomatal pores in leaves enable plants to regulate the exchange of gases with their environment. Variations of the pore aperture are mediated by controlled changes of potassium salt concentrations in… (More)

A slow anion channel in guard cells, activating at large hyperpolarization, may be principal for stomatal closing.

• Birgitta Linder, Klaus Raschke
• FEBS letters
• 1992

Slowly activating anion channel currents were discovered at micromolar 'cytoplasmic' Ca2+ during patch-clamp measurements on guard-cell protoplasts of Vicia faba and Xanthium strumarium. They… (More)

Ion Channels in the Xylem Parenchyma of Barley Roots (A Procedure to Isolate Protoplasts from This Tissue and a Patch-Clamp Exploration of Salt Passageways into Xylem Vessels.

• L. H. Wegner, Klaus Raschke
• Plant physiology
• 1994

To identify mechanisms for the simultaneous release of anions and cations into the xylem sap in roots, we investigated voltage-dependent ion conductances in the plasmalemma of xylem parenchyma cells.… (More)

Separation and measurement of direct and indirect effects of light on stomata.

• Thomas D Sharkey, Klaus Raschke
• Plant physiology
• 1981

Conductance for water vapor, assimilation of CO(2), and intercellular CO(2) concentration of leaves of five species were determined at various irradiances and ambient CO(2) concentrations.… (More)

Limitation of Photosynthesis by Carbon Metabolism : II. O(2)-Insensitive CO(2) Uptake Results from Limitation Of Triose Phosphate Utilization.

• Thomas D Sharkey, Mark Stitt, Dominique Heineke, Robert T. Gerhardt, Klaus Raschke, Henna Heldt
• Plant physiology
• 1986

The occurrence of O(2)-insensitive photosynthesis at high quantum flux and moderate temperature in Spinacia oleracea was characterized by analytical gas exchange measurements on intact leaves. In… (More)

Topography of photosynthetic activity of leaves obtained from video images of chlorophyll fluorescence.

• Peter Daley, Klaus Raschke, Jerry T. Ball, Joseph A. Berry
• Plant physiology
• 1989

The distribution of photosynthetic activity over the area of a leaf and its change with time was determined (at low partial pressure of O(2)) by recording images of chlorophyll fluorescence during… (More)

Stomatal opening quantitatively related to potassium transport: evidence from electron probe analysis.

• G. D. Humble, Klaus Raschke
• Plant physiology
• 1971

When stomata of Vicia faba opened (from a stomatal aperture of about 2 micrometers to one of 12 micrometers) the solute content of the guard cells increased by 4.8 x 10(-12) osmoles per stoma. During… (More)

The delivery of salts to the xylem. Three types of anion conductance in the plasmalemma of the xylem parenchyma of roots of barley.

• B. Köhler, Klaus Raschke
• Plant physiology
• 2000

To explore possible pathways for anions to enter the xylem in the root during the transport of salts to the shoot, we used the patch-clamp method on protoplasts prepared from the xylem parenchyma of… (More)

Simultaneous requirement of carbon dioxide and abscisic acid for stomatal closing in Xanthium strumarium L.

• Klaus Raschke
• Planta
• 1975

Open stomata of detached leaves of Xanthium strumarium L. closed only when carbon dioxide and abscisic acid (ABA) were presented simultaneously. Three parameters of stomatal closing were determined… (More)
