A Kinetic Study on the Phosphate Efflux in Rice Roots - Rhythmic Phenomena of Phosphate Flux -
초록
This study was performed to elucidate the mechanisms involved in efflux process of phosphate from intact and excised roots of Oryza sativa (Tongil). The rapid loss of phosphate during the first 40-minutes of treatment is mainly from the cytoplasmic fraction, and the gradual loss taking place afterwards is possibly reflecting the losses at the tonoplast. During the first 60 minutes, loss of phosphate from the excised roots treated with KCN was more rapid than the control but slower thereafter. The effect of
