| 摘要 |
A cDNA encoding a plant sucrose-binding protein (SBP) is provided, together with modified SBPs having enhanced sucrose uptake activity in a yeast assay system. Nucleic acid vectors, transgenic cells and transgenic plants having modified sucrose uptake activity are also provided. The invention also relates to promoter sequences useful for controlling expression of transgenes in plants, including SBP transgenes. |
