为了探讨高尔基体与细菌增殖和周膜扩展的关系,用电子显微镜研究了大豆根瘤侵染细胞发育中高尔基体的变化.结果表明:幼龄侵染细胞中有高尔基体,但在成熟和衰老的侵染细胞中却几乎没有这种结构.高尔基体随幼龄侵染细胞中细菌的增多而增多,它们主要位于细菌附近.这些高尔基体的生理活性较高,不断向周围的细胞质分泌含有纤维状物质的小泡,有的小泡还在向细菌运动.一些小泡位于细菌的周膜上,其附近细菌的周膜常向外形成隆起,并有纤维状物质出现在其中.由此说明,大豆根瘤侵染细胞中的高尔基体参与了细菌的增殖和周膜的扩展.

In order to discuss the correlation between Golgi bodies and the increase of bacteria and their peribacteroid membranes , the changes of Golgi bodies were studied by electron microscopy during the development of the infected cells in soybean root nodules. Results showed that the infected cells were divided into young infected cell,mature infected cell and senescent infected cell. They were increased with the bacteria in the young infected cells, but this structure almost disappeared in mature and senescent infected cells. Golgi bodies were mainly located near bacteria and were very active in bio-physiology , they often secreted vesicles with fibriHiform material to surrounding cytoplasm, some vesicles continuously moved to near bacteria, some vesicles even closed to the bacteria or were located on the peribacteroid membranes of bacteria and some peribacteroid membranes of near bacteria formed different bulges out with fibrilliform material. Thus it cound revealed that Golgi bodies participated in the increase of the bacteria and their peribacteroid membranes during the development of the infected cells of soybean root nodules.
