The results showed that: 1 under the hydroponic culture established in this research, the experimental wheat plants grew well andperformed the typical architecture responses when exposed in Pi deprivation. Hemi-qantitative RT-PCR revealed that the transcriptional level of known P response gene changed dramatically; 2 In general the length of wheat root axis and the root/ shoot ratio arose when the Pi supply was deprived, however, the change models differed among different wheat genotypes. The investigation on their molecular basis would offer the useful clue for seeking high phosphorus efficiency protoplasma and gene resources of wheat.

结果表明：1在研究建立的小麦水培体系中，小麦植株生长正常并对磷饥饿胁迫条件做出发育形态建成水平的反应；半定量RT-PCR分析显示在此体系中小麦磷响应基因也在转录水平上产生显著变化；2在水培条件下不同基因型小麦对磷饥饿胁迫的反应总体上表现在根轴长度和根冠比有所提高，但不同基因型小麦的反应特点有差异；对这些反应特征的分子机理的深入分析可为有效筛选磷高效小麦新种质以及发掘磷高效基因资源提供线索。
