MORPHOGENESIS OF THE MEMBRANOUS LABYRINTH IN PENAEID SHRIMP CELLS INFECTED WITH PENAEUS-MONODON BACULOVIRUS (MBV)

The morphogenesis of a highly organized cellular membrane structure, a membranous labyrinth (ML), in the cells of penaeid shrimp infected wi th Penaeus monodon baculovirus (MBV) is described. The ML possibly ori ginates from dilated Golgi apparatus, endoplasmic reticulum (ER) or th e outer nuclear membrane. The ML apparently grows by proliferation of the cellular membranes of these systems. In addition, its degree of de velopment was correlated with-stages of MBV reproduction.
