Calcium Channels And Signal Transduction In Plant Cells

Calcium signal transduction is a central mechanism by which plants sense and respond to enstoneenous 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.

Calcium signaling - Wikipedia

Calcium signaling is the use of calcium ions (Ca 2+) to communicate and drive intracellular processes often as a step in signal transduction.Ca 2+ is important for cellular signalling, for once it enters the cytosol of the cytoplasm it exerts allosteric regulatory effects on many enzymes and proteins.Ca 2+ can act in signal transduction resulting from activation of ion channels or as a second .

Signal transduction - Wikipedia

Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events, most commonly protein phosphorylation catalyzed by protein kinases, which ultimately results in a cellular response.Proteins responsible for detecting stimuli are generally termed receptors, although in some cases the term sensor is used.
