| 41. | The presence of water is important because the zoospores have no way to reach a host without swimming.
|
| 42. | The zoospores make toxins that are shed into the water, basically drugging the fish and making them lethargic,
|
| 43. | The sporangia ripen and release zoospores, which infect plant roots by entering the root behind the root tip.
|
| 44. | Once zoospores reach the root or seed, they encyst, germinate, and infect via a germ tube.
|
| 45. | On the other hand, encysted zoospores of P . colocasiae can survive for several months without a host.
|
| 46. | "It can transform from an amoeba to a toxic zoospore in two minutes, " she said.
|
| 47. | It contains a larger population of bacteria, particularly the cellulolytic bacteria, lower protozoa, and higher fungi zoospores.
|
| 48. | Upon release from the germinated resting spore, zoospores seek out a suitable substrate for growth using chemotaxis or phototaxis.
|
| 49. | The fungus zoospores can survive within a temperature range of 4 25 �C and a pH range of 6 7.
|
| 50. | Chemicals such as deadzeins and genistein are released at the tip of the plant roots which attract the liberated zoospores.
