Zygosporangia

These two pictures (left and right) show what developing zygosporangia look like under a microscope.

Zygosporangia

Name: Rhizopus stolonifer (as seen below)

Characteristics: This fungus has a large range of hosts. Many fruits and vegetables are susceptible to this pathogen.To spread, haphea (known as stolons) grow over the surface of infected food and rhizoids penetrate and digest (by absorption) its host.

Environment:This fungus is commonly found on bread, vegetables, and soft fruits such as peaches. It is found throughout the world and is terrestrial.

Adaptations to the Environment: This fungus only undergoes reproduction when conditions are perfect in it's environment.To transfer to new environments  Rhizopus stolinifer spreads through contact with another unprotected host.

Ecological Roles: hundreds of crops in BC alone are ruined each year by this fungus.

Medical Roles: This fungus acts as an astringent, an antiseptic and is used in anti-inflammatory medicine.

Rhizopus stolinifer reproduces asexually and sexually. Assexually, sporangia produce up to 40 000 spores which scatter and germinate to produce stolons when the conditions are correct.sexually, two haphaes of different genders fuse to form gamatangia, where haploid gametes are formed.Then, two different mating types form a diploid nuclei which developes a thick wall making it a zygospore. In the right conditions the zygospores germinate, undergoes meiosis, then turn into hyphae. These haphae form sporangium, release spores,and each develop into a new mycelium.
