Outline of Final Research Achievements |
This study aimed to reveal the evolution and fungi-algae interaction based on the detailed observation of life cycle and manner of infection in chytrids, a primitive group of fungi. Chytrid ultrastructure was observed by transmission electron microscopy. Time-lapse microscopy was performed to observe their transition of life cycle stage, and fluorescent microscopy was performed to examine lectin-binding pattern in each life cycle stage. As a result, the lectin-binding patterns and the timing of zoospore release were different among life cycle stages or chytrid species. It was suggested that N-acetyl-D-glucosamine, one of the amino-sugars, was accumulated highly at the basal part of the rhizoid system.
