【摘要】 用电子显微镜放射自显影方法,研究了6-BA在烟草愈伤组织细胞中的定位。发现6-BA既可和质膜、液泡膜、质体和线粒体的膜相结合,又可和细胞核特别是核仁相结合。说明6-BA的受体蛋白既存在于质膜等细胞的膜系统上,又存在于细胞核内,呈现出多元位点现象。更多还原

【Abstract】 The localization of 6-benzyladenine in the callus cell of tobacco was studied by means of autoradiography. Electron microscope autoradiographs showed that the silver grains localized at not only cell membrane system such as plasma membrane, tonoplast, plastid membrane and mitochondrion membrane but also nucleus especially nucleolus. The results of the present study indicated that 6-benzyladenine receptor site associated with both cell membrane system and nucleus.更多还原
