| 21. | In the presence of nutrients, chlamydospores germinate by producing germ tubes that continue to grow and form mycelial masses.
|
| 22. | The liberated sporangia in turn can either germinate directly with a germ tube or begin to produce biflagellate motile zoospores.
|
| 23. | Most conidial spores do not germinate, and the few that do germinate in soil only have short germ tubes.
|
| 24. | The filamentous fungus " Neurospora crassa " ( bread mould ) produces CATs from conidia and conidial germ tubes.
|
| 25. | A conidium may form germ tubes ( germination tubes ) and / or conidial anastomosis tubes ( CATs ) in specific conditions.
|
| 26. | The zoospores escape from the cyst through a germ tube ~ 4 5 micrometers in diameter and 10 15 micrometers in length.
|
| 27. | Germ tubes give rise to appressorium which form haustorium and allow the pathogen to extract nutrients without penetrating the host s cell membrane.
|
| 28. | Once attached, the spore germinates by growing a germ tube and eventually locates a stoma by a touch responsive process known as thigmotropism.
|
| 29. | In the resistant sunflower cultivars, germination was still induced but the plant's germ tube never develops after penetration by the haustorium.
|
| 30. | When a conditioned seed receives a chemical signal from a host plant, it germinates, forming a germ tube which grows toward the host.
