| ABSTRACT |
The ultrastructural changes of the zygospore and zygosporangial walls of Rhizopus stolonifer during zygosporogenesis were studied by both scanning and transmission electron microscopy. The mature zygosporangial wall is composed of a primary, secondary, and tertiary layers. The mature zygospore wall is also multilayered. It was observed, in contrast to earlier reports, that the inner surface of the tertiary zygosporangial wall and zygospore wall are originally smooth and become warty at maturity. We suggest that this feature of wall development be added to the conventional model of zygosporogenesis in Rhizopus. |
