Chemically defined liquid media were devised which supported
excellent growth of Taphrina cerasi and T. deformans. When grown
in fermentation culture vessels, T. cerasi and T. deformans released
cytokinins into the liquid media. The presence of these cell division
factors was demonstrated with the soybean tissue assay which is
specific...
The teliospore of Tilletia caries germinates to produce a promycelium
with a whorl of primary sporidia at its tip. The time between
emergence of the promycelium and the development of primary sporidia
averaged 2.3 h. Fusion between compatible sporidia occurred within
an additional 3.8 h. Primary sporidia appeared to be...
