An oospore is a thick-walled sexual spore that develops from a fertilized oosphere in some algae, fungi, and oomycetes. [1] They are believed to have evolved either through the fusion of two species or the chemically induced stimulation of mycelia, leading to oospore formation. [2]

Under warm and moist soil conditions oospore germination is stimulated by the host exudates (Dyer and Windels, 2003). Oospores form a germ tube which develops vegetative hyphae that can directly infect the host (Dyer and Windels, 2003).

The meaning of OOSPORE is a spore (as of a fungus) produced by heterogamous fertilization.

The oospore, the fertilized female egg, has spirals on its surface that were imprinted by the spiraling protective cells that surrounded the oospore. Oospores from before about 225 million years ago had right-handed spirals, whereas those formed since that time have had left …

Zoospore motility allows it to move out of its host and spread through water or air while oospore motility allows it to travel only within a plant cell and not move freely unless it is a parasite that needs to be transported from one plant to another by insects or birds (zoospore reproduction).

As nouns the difference between zoospore and oospore is that zoospore is an alternative spelling of lang=en while oospore is a fertilized female zygote, having thick chitinous walls, that develops from a fertilized oosphere in some algae and fungi.

Sexual reproduction of an oospore is the result of contact between hyphae of male antheridia and female oogonia; these spores can overwinter and are known as resting spores. [4]: 409 Asexual reproduction involves the formation of chlamydospores …

These fungus-like eukaryotes show multiple sporulation pattern including the production of sporangium, zoospore, chlamydospore and oospore, which are critical for their survival, dispersal and infection on hosts.

Oospores and zygospores are the result of sexual reproduction in the Oomycota and Zygomycota, respectively. An oospore forms when an oogonium (female gamete) is fertilized by an antheridial (male gamete) nucleus; a characteristically thick wall and food reserves help to ensure survival.

oospore the thick-walled spore found, for example, in some fungi, and arising from the fertilization of the OOSPHERE derived from an OOGONIUM.
