In this research, the ~ and F2 of the crosses between a natural mutant 慪34?with super-minute grain and 慪38?with super-large grain,慡huhui 881擲huhui 527?with middle grain size were carried out to study the inheritance of the grain shape (grain length, grain width, grain thickness and grain length/width ratio) and 1000-grain weight. The main results are summarized as below:? The F1 grain length, grain width, grain thickness and 1000-grain weight of three crosses were lay between the two parents and tended to Y34, which indicated that those grain traits were all governed by the dominant effect of Y34 and influenced by both female and male parents. The differences of F1 grain length, grain width, grain thickness and 1000-grain weight of positive and negative crosses between Y38 and Y34 indicated the existence of cytogene effects.? The broad heritabilities of major grain traits were calculated.

本研究利用一份水稻极小粒自然突变材料Y34与一份水稻极大粒材料Y38、两份常规籽粒大小材料蜀恢881、蜀恢527的杂交F_1及F_2，对主要粒形性状（粒长、粒宽、粒厚、长宽比）及千粒重进行了遗传研究，根据遗传研究的结果利用微卫星标记结合F_2群分法对控制Y34短粒性状基因进行了分子标记定位，主要结果如下：●各组合F_1粒长、粒宽、粒厚和千粒重介于双亲之间且明显偏向于小值亲本 Y34，这表明粒长、粒宽、粒厚和千粒重均主要受小值亲本显性基因的控制并同时也受大值亲本核基因的影响。Y34与Y38正反交F_1在粒长、粒宽、粒厚、千粒重等性状上存在差异，表明存在细胞质效应。

Now we have known that SARS-CoV encoded 11 varietal proteins. They have 4 constitutive proteins: spike protein, membrane protein, envelope protein and nucleocapsid protein. Spike protein trimer form spike and exsertion? virus peplos on the surface. Spike protein is archi-surface antigen component of virus, it has acceptor binding and membrane fusion activity. Spike protein has important effect at tissue tropism, cell-fusion and toxicity. Nucleocapsid protein can bind genome RNA to shape neucleocapsid. Membrane protein and envelope protein are necessary constituent to shape virus peplos. Spike protein is I-type membrane glycoprotein, it mediate virus binding with host cell epimembranal acceptor and to fuse host cell membrane.

SARS-CoV属于巢状病毒目、冠状病毒科，为单正链RNA病毒，基因组全长约29.7kb，已知编码11种蛋白，其中包括4种结构蛋白，分别是刺突蛋白、包膜蛋白、小包膜蛋白和核蛋白或核壳体蛋白。S蛋白三聚体形成突起，伸出包膜表面。S蛋白是病毒的主要表面抗原成分，具有受体结合和膜融合活性，在组织嗜性、细胞融合和毒力等方面起重要作用。N蛋白与基因组RNA结合形成核衣壳。M蛋白和E蛋白是包膜形成所必需的成分。
