A S Reddy,B W Poovaiah,

The effect of inositol 1,4,5-trisphosphate (IP3) on Ca2+ release from microsomes of corn coleoptiles was investigated. Addition of micromolar concentrations of IP3 to Ca2+ loaded microsomes resulted in rapid release of 20-30% of sequestered Ca2+. Maximal and half maximal Ca2+ release occurred at 20 and 8 microM of IP3 respectively. Part of the Ca2+ released by IP3 was reaccumulated into microsomes within 4 min. The amount of Ca2+ released by IP3 was found to be dependent on free Ca2+ concentration in the incubation medium at the time of release. Maximum Ca2+ release was observed around 0.1 microM free Ca2+ concentration in the assay medium. These data suggest that IP3 might act as a second messenger in plants in a manner similar to animal systems by altering cytosolic levels of calcium.
