Studies in the life cycle of Allomyces javanicus Kniep

Abstract

The life cycle of Allomyces javanicus was studied with the hanging drop method under laboratory conditions. The isolate has a life cyrle similar to that already described in A. javanicus and A. arbuscula. Planonts from resistant sporangia do not germinate directly to produce gametophytic plants, but on the contrary, the latter germinate to produce plants like their immediate parents. Female and male gametes growing in the gametangia of relatively young sexual mycelia develop into asexual mycelia after conjugation, but some of the female gametes after germination develop into asexual mycelia without conjugation. © 1971 Dr. W.
