  2. Cytolysin - Wikipedia

    en.wikipedia.org/wiki/Cytolysin

    One specific type of cytolysin is the cholesterol-dependent cytolysin (CDC). CDCs exist in many Gram-positive bacteria. The pore forming process of CDCs require the presence of cholesterols on target-cell membranes. The pore size created by CDC is large (25–30 nm) due to the oligomeric process of cytolysins.

  3. Toxin - Wikipedia

    en.wikipedia.org/wiki/Toxin

    The debate is one of linguistic semantics. The word toxin does not specify method of delivery (as opposed to venom, a toxin delivered via a bite, sting, etc.). Poison is a related but broader term that encompasses both toxins and toxicants; poisons may enter the body through any means - typically inhalation, ingestion, or skin absorption. Toxin ...

  4. Microbial toxin - Wikipedia

    en.wikipedia.org/wiki/Microbial_toxin

    Some of these species produce harmful toxins such as botulinum toxin and tetanus toxin among others. Most Clostridium species that do have toxins typically have binary toxins with the first unit involved in getting the toxin into the cell and the second unit cause cellular stress or deformation. [6]

  5. Wound response in plants - Wikipedia

    en.wikipedia.org/wiki/Wound_response_in_plants

    The structure of a plant cell wall is incredibly important for wound responses, as both protect the plant from pathogenic infections by preventing various molecules from entering the cell. [ 1 ] Plants are capable of activating innate immunity, by responding to wounding events with damage-associated Molecular Patterns (DAMPs). [ 1 ]

  6. Phytochemical - Wikipedia

    en.wikipedia.org/wiki/Phytochemical

    Phytochemicals are chemicals of plant origin. [1] Phytochemicals (from Greek phyto , meaning "plant") are chemicals produced by plants through primary or secondary metabolism . [ 2 ] [ 3 ] They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, pathogens, or predators.

  7. Plant physiology - Wikipedia

    en.wikipedia.org/wiki/Plant_physiology

    For example, plant cells have a cell wall which maintains the shape of plant cells. Plant cells also contain chlorophyll, a chemical compound that interacts with light in a way that enables plants to manufacture their own nutrients rather than consuming other living things as animals do. Thirdly, plant physiology deals with interactions between ...

  8. Toxin-antitoxin system - Wikipedia

    en.wikipedia.org/wiki/Toxin-antitoxin_system

    A cell that carries two plasmids from the same incompatibility group will eventually generate two daughter cells carrying either plasmid. Should one of these plasmids encode for a TA system, its "displacement" by another TA-free plasmid system will prevent its inheritance and thus induce post-segregational killing. [13]

  9. Clostridium botulinum - Wikipedia

    en.wikipedia.org/wiki/Clostridium_botulinum

    C. botulinum is a Gram-positive, rod-shaped, spore-forming bacterium. [1] It is an obligate anaerobe, the organism survives in an environment that lacks oxygen.However, C. botulinum tolerates traces of oxygen due to the enzyme superoxide dismutase, which is an important antioxidant defense in nearly all cells exposed to oxygen. [7]
