Chloride is an essential micronutrient for plants growth however it accumulates in large amounts in tobacco plants rapidly. To evaluate the effects of chloride concentrations in irrigating water on yield and growth indices of tobacco plant which has an important economic value, an outdoor pot experiment was established in completely randomized design during 2010 crop year at Guilan Tobacco Rese...
The binding of chloride is known to shift the absorption spectrum of most long-wavelength-absorbing cone-type visual pigments roughly 30 nm to the red. We determined that the chloride binding constant for this color shift in the gecko P521 visual pigment is 0.4 mM at pH 6.0. We found an additional effect of chloride on the P521 pigment: the apparent pKa of the Schiff base in P521 is greatly inc...
Rat proximal convoluted tubules were perfused in vivo to examine the active and passive components of chloride absorption. Chloride flux was a linear function of the transepithelial electrochemical driving force, yielding a permeability coefficient of 20.6 X 10(-5) cm/s. In the absence of an electrochemical driving force, chloride absorption persisted at the rate of 131 peq/mm X min, thus demon...
Acyl Activating Enzyme3 (AAE3) was identified to be involved in the catabolism of oxalate, which is critical for seed development and defense against fungal pathogens. However, the role of AAE3 protein in abiotic stress responses is unknown. Here, we investigated the role of rice bean (Vigna umbellata) VuAAE3 in Al tolerance. Recombinant VuAAE3 protein has specific activity against oxalate, wit...
Gastric secretion of hydrochloric acid requires protons and chloride, yet the mechanisms and regulation of gastric chloride secretion remain unclear. We developed an in vivo technique to simultaneously measure acid/base and chloride secretion into the gastric lumen of anesthetized rats. The cannulated stomach lumen was perfused with weakly pH-buffered chloride-free solution containing a chlorid...
