1. Initially, germ tubes emerge from soil residing sclerotia that overwinter. 2. The most common are germ tubes which grow and develop into hyphae. 3. The germ tubes will grow to form the hyphae and fungal mycelia. 4. The conidial anastomosis tubes are morphologically and physiologically distinct from germ tubes . 5. From this germ tube , it grows a haustorium. 6. Secondary sporidia accomplish this by penetrating the epidermis of host glumes via germ tubes . 7. The germ tube differentiates, grows, and develops by mitosis to create somatic hyphae. 8. CATs are morphologically and physiologically distinct from germ tubes and are under separate genetic control. 9. Sporangia can infect taro leaves either directly via germ tubes or indirectly by producing zoospores. 10. Sporangia germinate directly in a nutrient medium by producing germ tubes that develop into mycelial masses.
