zygospore

Upon germination, a zygospore produces colonies that are genetically different from either parent.

Once two opposite mating types have made initial contact, they give rise to a zygospore through multiple steps.

After some time, the zygospore makes another sporangium, which then makes spores.

In sexual reproduction, a dark zygospore is produced at the point where two compatible mycelia fuse.

As the zygospore enlarges, so do the warty structures until there are contiguous around the entire cell.

A zygospore is a diploid reproductive stage in the life cycle of many fungi and protists.

These dark patches on the wall will eventually develop into warty structures that make up the thickness of the zygospore wall.

Meiosis usually occurs before zygospore germintation and there are a few main types of distinguishable nuclear behavior.

Meiosis occurs within the zygospore, and one of the resulting recombinant nuclei survives.

Azygospore is an asexually formed zygospore in fungi.

The zygosporangium typically contains a single zygospore.

A zygospore remains dormant while it waits for environmental cues, such as light, moisture, heat, or chemicals secreted by plants.

The gametangium develops into a zygospore, a thick-walled spore formed by the union of gametes.

For example, in zygomycetes, two gametangia (single cells at the end of hyphae) form upon good contact with each other and fuse into a zygospore.

For example, in zygomycetes the thick-walled zygosporangium cracks open and the zygospore inside gives rise to the emerging sporangiophore.

Type 1 is when the nuclei fuse quickly, within a few days, resulting in mature zygospore having haploid nuclei.

The zygote develops a resistant cell wall, forming a single-celled zygospore, the characteristic that gives its name to this group of fungi.

When good conditions resume, the zygospore will germinate, undergo meiosis, and produce new haploid algal cells.

When the environment is favorable, the zygospore germinates, meiosis occurs, and haploid vegetative cells are released.

Suspensors are filamentous structural formations employed by Fungi in holding a zygospore between two strains of hyphae.

Once conditions have improved the zygospore germinates and undergoes meiosis to produce haploid offspring of both mating types.

Progametangia from each strain grow towards each other and fuse into gametangia, forming a thick-walled zygospore.

Several cell wall modifications, as well as incorporation of sporopollenin (dark colour of spores) take place resulting in a mature zygospore.

Subsequently, the zygospore germinates and forms a sporangiophore whose sporangium contains both + and - haploid spores.

When the zygospore germinates, it undergoes meiosis, generating new haploid hyphae, which may then form asexual sporangiospores.
