Defense as in the bee, ant, termite, honey bee, wasp, poison dart frog and plants producing toxins. The toxins used as defense in species among the poison dart frog can also be used for medicinal purposes; Some of the more well known types of biotoxins include: Cyanotoxins, produced by cyanobacteria; Dinotoxins, produced by dinoflagellates
They are usually found in citrus fruit, and produce a bitter substance called limonoid that deters insect feeding. Glycosides are made of one or more sugars combined with a non-sugar like aglycone, which usually determines the level of toxicity. Cyanogenic glycosides are found in many plant seeds like cherries, apples, and plums.
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]
The toxins in poisonous plants affect herbivores, and deter them from consuming the plants. Plants cannot move to escape their predators, so they must have other means of protecting themselves from herbivorous animals. Some plants have physical defenses such as thorns, spines and prickles, but by far the most common type of protection is ...
Cardenolide toxins sequestered during the Monarch's larval stage from feeding on the plant remains in the adult, making it unpalatable to predators. Chemical defense is a strategy employed by many organisms to avoid consumption by producing toxic or repellent metabolites or chemical warnings which incite defensive behavioral changes.
As venomous organisms often use their neurotoxins to subdue a predator or prey very rapidly, toxins have evolved to become highly specific to their target channels such that the toxin does not readily bind other targets [29] (see Ion Channel toxins). As such, neurotoxins provide an effective means by which certain elements of the nervous system ...
For example, plants growing in nitrogen-poor soils will use carbon-based defenses (mostly digestibility reducers), while those growing in low-carbon environments (such as shady conditions) are more likely to produce nitrogen-based toxins. The hypothesis further predicts that plants can change their defenses in response to changes in nutrients.
In plants, resins, fats, waxes, and complex organic chemicals are exuded from plants, e.g., the latex from rubber trees and milkweeds. Solid waste products may be manufactured as organic pigments derived from breakdown of pigments like hemoglobin, and inorganic salts like carbonates, bicarbonates, and phosphate, whether in ionic or in molecular ...
