It is clear that both calcium and AOS are important modulators of the cellular signal transduction events following biotic and abiotic stress insults, although the long-distance signalling capabilities of some AOS implicate that they, or derived molecules, are more important for the induction of cross-tolerance.

Moreover, NO has also been reported to play a key role as signaling molecule in biotic and abiotic signal transduction pathways in plants. Calcium (Ca2+) is recognized as an essential nutrient for growth and devel- opment of plants and considered as one of the important signaling carriers in .
Calcium transport, calmodulin, signal transduction: DOI: 10.17660/ActaHortic.1995.383.2: Abstract: Calcium plays an important role in plant growth and development. Its importance as a mineral nutrient has two main purposes: apoplastic and symplastic. Apoplastic calcium has an important structural and functional role in the plant cell walls and ...
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.[PDF]
Calmodulin (CaM) (an abbreviation for calcium-modulated protein) is a multifunctional intermediate calcium-binding messenger protein expressed in all eukaryotic cells. It is an intracellular target of the secondary messenger Ca 2+, and the binding of Ca 2+ is required for the activation of calmodulin. Once bound to Ca 2+, calmodulin acts as part of a calcium signal transduction pathway by ...[PDF]

Mar 22, 2007 · Calcium ion (Ca 2+) is one of the very important ubiquitous intracellular second messenger molecules involved in many signal transduction pathways in plants.The cytosolic free Ca 2+ concentration ([Ca 2+] cyt) have been found to increased in response to many physiological stimuli such as light, touch, pathogenic elicitor, plant hormones and abiotic stresses including high salinity, .

Summary. In plants, calcium acts as a second messenger in the regulation of a variety of physiological and metabolic processes. For signal transduction via calcium, transient and often local elevations in the level of cytosolic Ca 2+ must occur. This requires a well-controlled co-operation of tightly regulated Ca 2+-channels and active Ca 2+-transporters such as primary Ca 2+-ATPases and the H ...[PDF]
downstream components of the signal transduction pathways, rather than calcium and cGMP themselves. Furthermore, we have found that the calcium/cGMP-dependent pathway has a lower requirement for cGMP than does the cGMP-dependent pathway. The role of these phenomena in the regulation of plant photoresponses is discussed.
In response to a signal relayed by a signal transduction pathway, the cytosolic calcium level may rise, usually by a mechanism that releases calcium from the cell's ER. The pathways leading to calcium release involve still other messengers, inositol triphosphate (IP3) and diacylglycerol (DAG).

Metabolism vs. Signal Transduction Metabolism • Provides mass transfer • Quantity of converted material: μMor mM • A metabolic network is determined by the present set of enzymes • The catalyst to substrate ratio is low (quasi-steady-state assumption in Michaelis-Menten kinetics) Signal Transduction • Provides information transfer
Aug 23, 2019 · Gangliosides are associated with calcium ions which is thought to have a role in neuronal function. Ganglioslide micelles bind to calcium ions with high affinity and may play a significant role in synaptic transmission. It has been reported that sphingosine and ceramide mediate the release of calcium from intracellular stores.
