The rate of Ca2+ accumulation in plasmalemma vesicles isolated from quiescent and sprouting potato (Solanum tuberosum L.) tubers and the effect of 10(-5) - 10(-10) M jasmonic acid on the accumulation of Ca+2 in plasmalemma vesicles and its efflux were studied. It was found that potato tuber plasmalemma contains a Ca+2, Mg+2-ATPase whose activity decreases upon the transition from forced quiescence to growth. The direction of the effect ofjasmonic acid on Ca+2, Mg+2-ATPase (stimulation or suppression) depends on the physiological state of tubers and the phytohormone concentration. |
