本文研究了菜豆叶腺和玉米根皮层细胞中部分被膜系统和被膜小泡的形成和分布。部分被膜以网状结构存在，其要么稀疏分支要么广泛闭合。包被的囊泡和包被的膜区域可以出现在这样的网状物附近的所有点处。高尔基体堆叠膜，虽然在许多情况下与部分被膜的网衣相连，但并没有一致的取向。偶尔，网衣和相关的被膜小泡位于远离任何高尔基体堆叠的位置。我们还对洋葱、甜菜和烟草等植物的组织进行了观察，发现所有材料都有部分被膜网。我们认为，膜流可能发生从部分包被的网要么高尔基堆栈或其他细胞内的隔间。
SummaryThe form and distribution of partially-coated membrane systems and coated vesicles in the leaf glands ofPhaseolus and the root cortical cells ofZea were investigated. Partially-coated membranes exist as a reticulum which is either sparsely branched or extensively anastomosed. Coated vesicles and coated membrane regions may occur at all points that are in the vicinity of such a reticulum. Golgi stack membranes, though associated with the partially-coated reticulum in many cases, show no consistent orientation to it. Occasionally, the reticulum and the associated coated vesicles are located away from any Golgi stack. We examined other plant tissues from such species asAllium cepa, Beta vulgaris andNicotiana tabacum and the partially-coated reticulum was observed in all material. We suggest that membrane flow may be occurring from the partially-coated reticulum to either the Golgi stack or to other intracellular compartments.
