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。

The seed embryoes were penetrated by 〓 ion beams of 75 MeV/u and the seed endosperms were implanted by the proper degraded 〓 ions, and soluble protein of the seedling in M1 generation was divided into 5 sections to analyze their changes at different molecular weight. 1 In comparison with control, the relative content of the second section (molecular weight is heavier in all sections) of all irradiated materials got down, while the relative content of the fifth section (molecular weight is the lightest) of those went up. 2 The penetrating seeds made the relative content of the first section (molecular weight is the heaviest) and the third section (mid-molecular weight) drop, while the fourth section went up. Moreover, the changes of the third section and the fourth section of the penetrated materials were clearly different from those of the implanted materials. 3 The difference between implanted embryo and implanted endosperm existed in deeper dropping of the first section and higher rising of the fifth section on relative content of soluble protein of the latter. 4 On irradiated materials at lower doses, there were exceptional changes of soluble protein, it may be thought that there was excited effect of low dose.

1.75MeV／u 〓O〓离子经过适当降能后注入小麦种子的不同部位和贯穿整个种子，对其M1代幼苗的可溶性蛋白质组分以及电泳中不同区段蛋白质组分相对含量加以分析，结果表明：1）同对照相比，随着辐照剂量的增加，所有辐照材料第二区段蛋白质组分的相对含量下降；而第五区段蛋白质组分的相对含量升高。2）种子的贯穿处理，同时也引起第一区段和第三区段蛋白质组分相对含量的下降以及第四区段的升高；其中第三、四区段的变化明显区别于注入效应。3）注入胚和胚乳的区别在于后者第一区段蛋白质组分相对含量的较大下降和第五区段的较大提高。4）小剂量辐照的材料，可溶性蛋白质组分的变化异常，可能与低剂量辐射兴奋效应有关。

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.

Highly active, small-molecule furin inhibitors are attractive drug candidates to fend off bacterial exotoxins and viral infection. Based on the 22-residue, active Lys fragment of the mung bean trypsin inhibitor, a series of furin inhibitors were designed and synthesized, and their inhibitory activity toward furin and kexin was evaluated using enzyme kinetic analysis. The most potent inhibitor, containing 16 amino acid residues with a Ki value of 2.45×10~(-9) M for furin and of 5.60×10~(-7) M for kexin, was designed by three incremental approaches.
