sporulation

(noun)

The process of a bacterium becoming a spore.

Examples of sporulation in the following topics:

  • Sporulation in Bacillus

    • Sporulation is the last-ditch response to starvation; it is suppressed until alternative responses prove inadequate.
    • Although sporulation in B. subtilis is induced by starvation, the sporulation developmental program is not initiated immediately when growth slows due to nutrient limitation.
    • Sporulation is a last-ditch response to starvation, and it is suppressed until alternative responses prove inadequate.
    • Sporulation requires a great deal of time and energy, and it is essentially irreversible, making it crucial for a cell to monitor its surroundings efficiently and ensure that sporulation is embarked upon at only the most appropriate times.
    • Two transcriptional regulators, σH and Spo0A, play key roles in initiation of sporulation.

  • Cyclospora Diarrheal Infection

    • The oocysts demonstrate the ability to undergo sporulation in a crop and water host as well beginning with the oocyst stage.
    • In the environment (2), sporulation occurs after days or weeks at temperatures between 22°C to 32°C, resulting in division of the sporont into two sporocysts, each containing two elongate sporozoites (3).
    • Fresh produce and water can serve as vehicles for transmission (4) and the sporulated oocysts are ingested (in contaminated food or water) (5).

  • Toxoplasmosis

    • The oocysts will then take 1-5 days to sporulate in the environment and become infective.
    • Cats, can become infected after consuming intermediate hosts that are infected with tissue cysts or by ingesting sporulated oocysts .

  • Non-Spore-Forming Firmicutes

    • These comprise a class of Firmicutes and are Gram-positive, low-GC, acid-tolerant, generally non-sporulating, non-respiring rod or cocci that are associated by their common metabolic and physiological characteristics.

  • Endospores

    • Sporulation is now complete, and the mature endospore will be released when the surrounding vegetative cell is degraded.

  • Reporter Fusions

  • Firmicutes

    • Sporulation is now complete, and the mature endospore will be released when the surrounding vegetative cell is degraded.

  • Genetically Modified Organisms (GMOs)

    • Bacillus thuringiensis (Bt) is a bacterium that produces protein crystals during sporulation that are toxic to many insect species that affect plants.

  • Chromalveolata: Stramenopiles

    • Most species of diatoms reproduce asexually, although some instances of sexual reproduction and sporulation also exist.
