  2. Endospore - Wikipedia

    en.wikipedia.org/wiki/Endospore

    An endospore stain of the cell Bacillus subtilis showing endospores as green and the vegetative cell as red Phase-bright endospores of Paenibacillus alvei imaged with phase-contrast microscopy. An endospore is a dormant, tough, and non-reproductive structure produced by some bacteria in the phylum Bacillota.

  3. Sporulation in Bacillus subtilis - Wikipedia

    en.wikipedia.org/wiki/Sporulation_in_Bacillus...

    B. subtilis can divide symmetrically to make two daughter cells (binary fission), or asymmetrically, producing a single endospore that is resistant to environmental factors such as heat, desiccation, radiation and chemical insult which can persist in the environment for long periods of time. The endospore is formed at times of nutritional ...

  4. Endospore staining - Wikipedia

    en.wikipedia.org/wiki/Endospore_staining

    Endospores can last for decades in multiple hard conditions, such as drying and freezing. This is because the DNA inside the endospore can survive over a long period. Most bacteria are unable to form endospores due to their high resistance, but some common species are the genera Bacillus ( over 100 species) and Clostridium (over 160 species). [2]

  5. Sporogenesis - Wikipedia

    en.wikipedia.org/wiki/Sporogenesis

    The term sporogenesis can also refer to endospore formation in bacteria, which allows the cells to survive unfavorable conditions. Endospores are not reproductive structures and their formation does not require cell fusion or division. Instead, they form through the production of an encapsulating spore coat within the spore-forming cell.

  6. Bacterial cell structure - Wikipedia

    en.wikipedia.org/wiki/Bacterial_cell_structure

    Endospores are bacterial survival structures that are highly resistant to many different types of chemical and environmental stresses and therefore enable the survival of bacteria in environments that would be lethal for these cells in their normal vegetative form.

  7. Bacteria - Wikipedia

    en.wikipedia.org/wiki/Bacteria

    Some genera of Gram-positive bacteria, such as Bacillus, Clostridium, Sporohalobacter, Anaerobacter, and Heliobacterium, can form highly resistant, dormant structures called endospores. [93] Endospores develop within the cytoplasm of the cell; generally, a single endospore develops in each cell. [94]

  8. Clostridium tetani - Wikipedia

    en.wikipedia.org/wiki/Clostridium_tetani

    Upon exposure to various conditions, C. tetani can shed its flagellums and form a spore. [1] Each cell can form a single spore, generally at one end of the cell, giving the cell a distinctive drumstick shape. [1] C. tetani spores are extremely hardy and are resistant to heat, various antiseptics, and boiling for several minutes. [2]

  9. Endospory in plants - Wikipedia

    en.wikipedia.org/wiki/Endospory_in_plants

    There is debate as to whether endospory or heterospory evolved first. Some debate centers upon the requirement of endospory to develop before heterospory. [2] Endospory is assumed to follow heterospory but it has been suggested that without endospory, early plant species dependency on water fertilization and environmental impacts on gametophytic gene expression would have reduced the chances ...
