CHANGE IN ULTRASTRUCTURE OF ASPERGILLUS ORYZAE CONIDIA DURING GERMINATION

Abstract

Electron microscopic studies have been made on ultrathin sections of Aspergillus oryzae conidia fixed in potassium permanganate. Staining of sections in uranyl acetate solution was necessary to disclose the fine structure of dormant cells. Although the remarkable difference could not be seen between dormant and germinated conidia, some minor differences in membranous systems were noticed. In dormant conidium, invaginations of cytoplasmic membrane and the presence of unidentified membranous organelles were characteristic.
