Abstract

This article describes a new organelle found in the cytoplasm of the growth stage fish oocytes. In particular, we describe its organization at the morphological level and investigate its composition by different cytochemicaland immunocytochemical approaches with both light and electron microscope. The conclusion is that the body is a peculiar protein scaffold functioningas a temporary trap for the storage of rRNA in the mid to late growth stage oocytes. Its presence would be related to the reorganization of the mass of amplified rDNA in micronucleoli and to the consequent temporary stop in the rRNA synthesis. Mel. Reprod. Dev. 56:198-206, 2000.
