摘要
本文选用大豆属Skja亚属的栽培大豆(Glycine max)和野生大豆(G.Soja)以及中间型(G. gracilis)为材料,应用电子显微镜技术观察了子叶细胞伸展发育时期的超微结构特征,发现了蛋白体形成方式的差异。栽培大豆(品种Harosoy)子叶细胞蛋白体以中心单点式聚集贮藏蛋白质,而且其合成蛋白质的运输以内质网囊泡为主。野生大豆(Jw93—1,Jw98—2)子叶细胞蛋白体以边缘多点式聚集贮藏蛋白质,其合成蛋白质以直接或间接的途径运输至蛋白体内。
The developing cotyledon ultrastructure observed by electron-microscope was shown to be different betweer cultivated soybean (G. max) and wild soybean (G. soja) on protein body depositing way. The protein bodies of developing cultivated soybean cotyledons were filled by central-single-point depositing way, and the storage protein was transported maimly by ER cisterna during cotyledons developing. The protein bodies of developing wild soybean cotyledons were filled by edge-multi-point depositing way and the storage protein was transported by direct and indirect way to protein bodies.
