Abstract
Inositol 1,4,5-trisphosphate (IP{sub 3}) was determined by competition with ({sup 3}H)-IP{sub 3} for binding to an IP{sub 3} specific protein. A hypertonic mannitol, sorbitol or lactose shock induced an increase in the rate of K{sup +} uptake and raised the IP{sub 3} content of Beta vulgaris slices, excised Vigna mungo and Sorghum bicolor roots, as well as attached V. mungo roots. Increased K{sup +} uptake could also be induced by compounds that artificially induce the PIP cascade, or mimic it's products. A hypertonic shock, administered to intact B. vulgaris slices, further enhanced the phosphorylation of a 20 kD protein in the plasmalemma. Maximal IP{sub 3} content was found 10 min after hypertonic induction and maximal K{sup +} uptake was obtained 10 min later. The effect of a continuous hypertonic treatment on IP{sub 3} content, but not on K{sup +} uptake, was transient. Li{sup +} decreased the rate of IP{sub 3} metabolism.
