Abstract
|
|
|
The origins and the functions of the multivesicular bodies and thevarious structures of the membranes related to the cytolysomes were studied in the mycelium cells of Rhizopus nigricans, Aspergillus niger and A. ochraceus, in the hymenium and basidium cells of .Aggricus ,bisporus and Rhizopogon rubescens, in the cells of assimilation tissue of Marchtantia polymorpha and -Pogonatum inflexum and in the mesophyll cells of Pteridium agiulinusn, Pinus densiflora; Ginkgo biloba and Panax ginseng fixed with glutaraldehyde-paraformaldehyde Os04.
In Rhizopus, nigricans, Aspergillus ,niger. A. ochraceus, Agricus bisporus and Rhizopogon rubescens, the concentric-multilamellar, multivesicular, myelin-vesicle-tubular and concentric parallel-lamellar"complexes were originated from the plasmalemma; while in Marchantia polymorpha, Pogonatum inflexum,: Pteridium aquilinum, Pinus densiflora, Ginkgo biloba and Panax ginseng,.. they were originated from plasma lemma and the cytoplasm.
The structures. originated from the plasma lemma may be grouped into multivesicular body and myelin-like structure, both forming the secondary vacuoles or protruding into the central vacuoles and finally degrading. In some cases, endoplasmic reticulum within the cytoplasm encloses-some part of the cytoplasm to form a circle. where the membranous, lamellae increase .in number, while thee enclosed, decrease to be,eventually-replaced by the multilameliarm structure which is released into- the vacuoles and subsquently degraded.
The structures. originated from the. cytoplasm are believed to be the cytosegresomes or cytolysomes closely related, to the differentiation of the vacuoles.
The possible fate of these structures are also discussed.
