To determine the growth rate, all tested strains were cultured on 10% V8 agar medium at 25 °C in the dark. Colony diameters were measured and photographed after seven days. To quantify oospore production, all tested strains were cultured on LBA agar medium in 7 cm petri plates at 25 °C in the dark. The oospores produced by different strains were photographed and counted with at least 30 images per strain. The different morphology of oospores was photographed, and the content ratio was calculated.

“The Aphanomyces life cycle has two phases. The first phase is the oospore stage,” explains Chatterton. “This is a fairly large, single-celled resting spore, surrounded by a very thick cell wall. The oospore can survive in soil for six to 10 years, or more. When a suitable host is around, the oospores germinate, to produce zoospores.

Le oospore si formano durante l’intero periodo vegetativo in seguito alla fecondazione di un oogonio (organo femminile) da parte di un anteridio (organo maschile). Durante l’inverno le oospore, che raggiungono la maturità in autunno, rimangono dormienti e la loro germinazione in primavera è influenzata principalmente dalle condizioni di temperatura e dalle precipitazioni.

Zoospores move via wind and rain and act as the major cause of disease spread during the season, infecting new leaves, shoots and eventually even cones. The reproductive cycle that produces zoospores may repeat multiple times over the season, depending on temperature and moisture availability. Alternately, mycelium may also yield a resting spore (oospore) that it produces through sexual recombination. Oospores are typically more resistant to environmental changes and are often referred to as resting spores. It is unclear at this time if Michigan’s climate provides environmental conditions conducive to oospore production.
