    • The present invention relates to methods and materials in the field of molecular biology and the regulation of protein synthesis through plant genetic engineering. More particularly, the invention relates to newly-isolated nucleotide sequences, nucleotide sequences having substantial identity thereto and proteins encoded thereby. The invention also involves the introduction of foreign nucleotide sequences into a plant genome, wherein the introduction of the nucleotide sequence effects an increase in the plant's ability to transport phosphate. Plant transformants harboring a DNA construct comprising a promoter operably linked to an inventive nucleotide sequence demonstrate increased levels of phosphate transporter proteins, rendering the plant better able to sustain growth in a phosphate-deficient substrate.
    • 本发明涉及分子生物学领域的方法和材料以及通过植物遗传工程调节蛋白质合成。 更具体地,本发明涉及新分离的核苷酸序列,与其具有实质同一性的核苷酸序列及其编码的蛋白质。 本发明还涉及将外源核苷酸序列引入植物基因组中,其中引入核苷酸序列会影响植物运输磷酸盐的能力。 携带包含可操作地连接到本发明核苷酸序列的启动子的DNA构建体的植物转化体表现出增加的磷酸转运蛋白水平,使得植物能够更好地维持磷酸盐缺乏的底物中的生长。
