Goodchild, D. J. (Commonwealth Scientific and Industrial Research Organization, Canberra, Australia), and F. J. Bergersen. Electron microscopy of the infection and subsequent development of soybean nodule cells. J. Bacteriol. 92:204-213. 1966-Electron microscopy of thin sections of the developing central tissue cells of young soybean root nodules has shown that infection is initiated by a few infection threads which penetrate cells of the young central tissue. Extension growth of the threads may be a result of pressure developed from the growth of the bacteria within the threads. Release of bacteria from a thread is preceded by the development on an infection thread of a bulge with a cellulose-free membrane-bounded extension; bacteria move from this into the host cells by an endocytotic process and remain enclosed in an infection vacuole which is bounded by a membrane of host-cell origin. Multiplication of the intracellular bacteria takes place within these vacuoles. Until the host cell becomes filled with bacteria, the vacuoles separate into discrete units at each division. Later, division of the bacteria occurs within each vacuole, thus leading to the mature structure of the central tissue cells in which several bacteria are enclosed within each membrane-bounded unit.

J. 伯格森。大豆根瘤细胞感染及后续发育的电子显微镜观察。《细菌学杂志》92:204 - 213。1966年——对年轻大豆根瘤发育中的中央组织细胞薄切片的电子显微镜观察表明，感染由少数侵染丝引发，这些侵染丝穿透年轻中央组织的细胞。侵染丝的延伸生长可能是丝内细菌生长产生压力的结果。细菌从侵染丝释放之前，侵染丝上会形成一个带有无纤维素膜包被延伸部分的凸起；细菌通过胞吞过程从这里进入宿主细胞，并被包裹在一个由宿主细胞来源的膜界定的侵染液泡中。细胞内细菌在这些液泡中繁殖。在宿主细胞充满细菌之前，液泡在每次分裂时会分离成离散的单元。后来，细菌在每个液泡内进行分裂，从而形成中央组织细胞的成熟结构，其中每个膜包被单元内都包有几个细菌。
