Development and nature of the partition layer in Tilletia caries teliospore walls.

摘要

Developing Tilletia caries teliospores were studied with thin sectioning procedures. After the W1 and W2 spore walls are formed, lamellar material begins to form adjacent to the W2 wall layer. The patches of lamellar material become continuous, and additional layers are added. After the W3 wall starts to form, the lamellar material is difficult to see without special staining. The lamellar material makes it difficult to get resins to penetrate the partition layer of teliospore walls.
