The results showed that OsAgpS1a transcripts and the reporter gene GUS driven by the OsAgpS1a promoter had a similar expression pattern that abundantly expressed in endosperms but very low in leaves, whereas OsAgpS1b transcripts and the reporter gene GUS driven by the OsAgpS1b promoter own other similar expression pattern that expressed at a low level in leaves, roots and early development endosperms of rice.

结果表明，两个启动子与其下游转录本的表达模式完全一致，即OsAgpS1a转录本和OsAgpS1a上游启动子控制的GUS基因主要在胚乳中高水平表达，在叶片中有很低水平的表达；而OsAgpS1b转录本和OsAgpS1b上游启动子控制的GUS基因主要在叶片和胚乳发育早期低水平表达。

Expression patterns of genes differentially expressed in starch metabolism and cell cycle during endosperm development7 DAP kernals, 15 DAP endosperms and 25 DAP endosperms of B73, ae/wx and sh1 were used to study the expression patterns of 18 differentially expressed genes in sugar metabolism and 9 differentially expressed genes in cell cycle. We found that the expression patterns of Pul, SBEⅡa, UGPase, SUS3, SSⅡa in sh1 and Sh2-1, SUS3, SSⅡa in ae/wx were altered, revealing that these genes may interact with each other.

碳水化合物代谢基因和细胞周期基因随胚乳发育的变化以B73、ae/wx、sh1授粉后7天种子、15天和25天胚乳为材料，分析18个糖代谢差异基因和9个细胞周期调节相关的差异基因的表达模式，研究发现sh1突变体中Pul、SBEⅡa、UGPase、SUS3和SSⅡa基因表达模式发生改变，ae/wx突变体中Sh2-1、SUS3和SSⅡa基因表达模式发生改变，揭示了突变体对这些基因的巨大影响，反映了它们可能存在相互作用。

At the meantime, rigid endosperms enwrap the embryo.

这也是其发芽困难的主要原因。
