🔬 Subdivision Zygomycotina
Defining characters and examples of Zygomycotina relevant to plant pathology study.
Zygomycotina includes fast-growing fungi with simple mycelial organization and distinctive sexual reproduction through zygospore formation.
Diagnostic Characteristics
Main features:
- Aseptate or coenocytic mycelium.
- Asexual reproduction by sporangiospores.
- Sexual reproduction by zygospores.
- Mostly saprophytic, with some weak pathogens.
Asexual Reproduction
Sporangia are produced on sporangiophores and release many sporangiospores that aid quick colonization of substrates.
Sexual Reproduction
Fusion of compatible gametangia produces a thick-walled zygospore, which acts as a resistant survival structure.
Pathological Importance
Although many species are non-pathogenic, members can be associated with soft rots, seedling decay, and post-harvest spoilage under high humidity.
Commonly Discussed Genera
In basic mycology and pathology teaching:
- Rhizopus.
- Mucor.
