Update on Genetic Identities of Plant Calcium Channels Plant Calcium-Permeable Channels
The transient elevation of free calcium ion concentration in the cytosol and organelles of plant cells is a wellestablished phenomenon. As discussed in this Focus issue on calcium signaling, these elevations occur in response to a range of biotic and abiotic stimuli (McAinsh and Pittman, 2009; Dodd et al., 2010). Recently, transcriptomic analyses coupled with calcium determinations have demonst...
متن کاملCalcium-permeable channels in HeLa cells.
Calcium-permeable channels with a slope conductance of 9 pS were revealed in excised inside-out patches of cultured HeLa cells. Over a potential range from -80 to -10 mV, unitary inward currents were recorded with 110 Ca2+ in the pipette in artificial "intracellular" solutions containing impermeant anions. Channel activity was not considerably affected by varying free calcium concentration betw...
متن کاملCalcium-permeable ion channels in pain signaling.
The detection and processing of painful stimuli in afferent sensory neurons is critically dependent on a wide range of different types of voltage- and ligand-gated ion channels, including sodium, calcium, and TRP channels, to name a few. The functions of these channels include the detection of mechanical and chemical insults, the generation of action potentials and regulation of neuronal firing...
متن کاملCalcium-permeable ion channels in the kidney.
Calcium ions (Ca(2+)) are crucial for a variety of cellular functions. The extracellular and intracellular Ca(2+) concentrations are thus tightly regulated to maintain Ca(2+) homeostasis. The kidney, one of the major organs of the excretory system, regulates Ca(2+) homeostasis by filtration and reabsorption. Approximately 60% of the Ca(2+) in plasma is filtered, and 99% of that is reabsorbed by...
متن کاملVoltage-dependent calcium-permeable channels in the plasma membrane of a higher plant cell.
Numerous biological assays and pharmacological studies on various higher plant tissues have led to the suggestion that voltage-dependent plasma membrane Ca2+ channels play prominent roles in initiating signal transduction processes during plant growth and development. However, to date no direct evidence has been obtained for the existence of such depolarization-activated Ca2+ channels in the pl...
