PLANT PHOSPHATE TRANSPORTER GENE AND METHOD OF REGULATING PLANT GROWTH WITH SAID GENE

摘要

A gene encoding a phosphate transporter protein has been isolated from Arabidopsis thaliana and its structure has been elucidated. By integrating the gene into a highly active expression vector to effect transformation into cultured tobacco cells, it has become possible to remarkably enhance the phosphate absorption by the transgenic cultured tobacco cells and to increase the growth rate of the cells. This technique is expected to be widely applicable to plants.
