| 11. | The pathogen persists as oospores in the soil.
|
| 12. | The oospores germinate to form usually one sporangia.
|
| 13. | The storage material is starch, except in the oospore, where oil also occurs.
|
| 14. | The zygote produced is named an oospore.
|
| 15. | It is also possible for oospores and mycelium to overwinter in the seeds of maize.
|
| 16. | Once infection season comes to an end, sexual reproduction occurs to form an oospore.
|
| 17. | The oospores are then left to overwinter in the dead plant s debris and the soil.
|
| 18. | Oospores are double walled and uninucleate during dormancy, but become multinucleate in preparation for germination.
|
| 19. | Chlamydospores are larger than oospores in size, and are only formed under certain environmental triggers.
|
| 20. | During the winter, oospores, which are sexual resting spores, survive in the soil.
