The invention relates to methods of producing a desired phenotype in a plant by manipulation of gene expression within the plant. The method relates to means which inhibit the level of PK220 gene expression or activity, wherein a desired phenotype such as increased water use efficiency relative to a wild type control plant. The invention also relates to nucleic acid sequences and constructs useful such methods and methods of generating and isolating plants having decreased PK220 expression or activity. 本发明涉及提高植物水分利用效率的方法和手段。本发明涉及通过对植物内部基因表达的操作，获得所需植物表型的方法。该方法涉及抑制PK220基因的表达水平或者活性的手段，相对于野生型对照植物，其中所需的表型例如水分利用率有所提高。本发明还涉及到核酸序列以及有用的构建物等方法，以及构建和分离具有降低的PK220表达或活性的植物的方法。
