Calciumbinding Proteins In Fungi And Higher Plants

Calcium has long been known to be required for many vital processes in fungi and plants. High levels of calcium are found in cell walls, vacuoles, and most organelles. In contrast, very low levels of calcium are present in the cytosol of fungal and plant cells. The most recent evidence indicates tha

Jul 01, 1994 Ca2-permeable channels showed slow and reversible inactivation. The single-channel conductance was 13 pS in 40 mM CaCl2. These data provide direct evidence for the existence of voltage-dependent Ca2 channels in the plasma membrane of a higher plant cell and point to physiological mechanisms for plant Ca2 channel regulation.

Calciumpermeable Channels In Plant Cells Jammes 2011

Sep 28, 2011 Calcium signal transduction is a central mechanism by which plants sense and respond to endogenous and environmental stimuli. Cytosolic Ca 2 elevation is achieved via two cellular pathways, Ca 2 influx through Ca 2 channels in the plasma membrane and Ca 2 release from intracellular Ca 2 stores. Because of the significance of Ca 2 channels in cellular signaling,

The Role Of Calcium In Exocytosis And Endocytosis In Plant

In both plant and animal cells secretion appears to be dependent on, or is triggered by, a rise in the level of internal free calcium ions from about 10 7 to 10 6 M or even higher. In these eukaryotes internal organelles take up calcium and maintain a low level of calcium in the cell, offsetting the inflow of calcium from the plasma membrane.
