A lot of the poisonous plants are things that people never consider eating but are used in OTC drugs or were when I was a lot younger. You can hardly get past the first page of ANY toxicology textbook without reading that the dose makes the poison. All of the toxins you mentioned, digitalis, nicotine,... are not mild poisons, as they have fairly low LD50's. Butulina toxin is one of the most toxic of all poisons, but properly diluted is used to take the wrinkles out of John Kerry's forehead. In the other extreme, water has a very high LD50, but people have killed themselves by drinking too much of it. Again, it is the dose that makes the poison. John |

For example, aflatoxin is one of the most highly toxic and carcinogenic compounds there is, but it is only toxic to animals that have certain monooxygenases that "activate" aflatoxin into its toxic state; it is also hard to see how making aflatoxin would protect a common fungus that grows in the soil or on peanuts and corn (Aspergillus flavus) from mammals that make the particular monooxygenase.

Thanks for the brief tutorial. And I am at a dead-end here of trying to connect poison with the theory that PlantKingdom is the quantum compliment dual of AnimalKingdom. My original reason for embarking on poisons was to try to wring or wrung out the idea that if Quantum Duality and not Darwin Evolution was at work here that poisons would be in a *gradation spectrum throughout both plant and animal kingdoms* whereas if Darwin Evolution was correct then there would be no gradation and there would be mostly spikes of high toxins and concentrated to particular genomes and family genomes. My original reasoning is that Quantum Duality in Biology is necessary because if only one kingdom existed on Earth without its dual compliment then many elements of the periodic chart of Chemical Elements would not be used in biology. Animals use calcium so much more than plants and plants use carbon so much more than animals. So by focusing in on poisons there should be a more evenly distribution of production of poisons in both animal and plant kingdoms if Quantum Duality is true and that Darwin Evolution would show less of this even distribution. Because Quantum Duality forces a larger use of the Chemical Elements and compounds. Mind you I believe the Darwin Evolution theory is somewhat accurate in many narrow-minded applications for it is a algorithm at best and not a true theory of science. So Darwin Evolution is a rule-of-thumb just like the old slide rulers we used in mathematics would give crude first approximate answers but not smack exact answers. So Darwin Evolution is like slide-rulers are to mathematics. But it appears as though there is not enough clear evidence in the toxins and poisons to be able to drive a wedge between Quantum Duality of the Kingdoms of biology and Darwin Evolution.

COMMENT: Of course. Indeed you only find plants trying to poison animals eating the wrong parts of them, like roots, stems, leaves. Which is why herbals medicines come from those things-- herbals are dilute plant poisons, as are many medicines, at base. The difference between herbs and spices is which part of the plant they come from-- spices are from parts the plants are more willing to give up, and thus are generally less toxic. Nor is it a coincidence that most medicinal plants come from tropical climates. In temperature climates, plants get rest from insects when winter kills them off, and they don't come back in numbers to do damage until later in the growing season. So some plants get along without much insect poison at all. In the tropics, it's chemical warfare ALL the time. Plants will discourage eating of fruits generally only if at the wrong time, by making them toxic or at least sour. It's pretty rare you find toxic fruits, and even then the plant is trying to discourage animals that don't carry seeds, rather than ones that do. SBH |

Are there any poisons involved here? I don't know. Given the way these plants work, I doubt it. But this would be the place to look. Can any animal that is trapped by a carnivorous plant kill/inhibit it and escape?) There are 3 trap systems that carnivorous plants use. Bottles, Sticky Snares, and Closing Boxes. (I made all those terms up for this post) Bottles are passive traps that contain digestive fluids, and generally downward pointing hairs to prevent escape. To escape, an animal must either not sink in the fluid, or be able to chew their way out, Another option would be to be immune to the digestive action of the fluids, which I believe that there are a few mosquitos or other flies that can do that, their larvae eat the plants victims, the adults escape because they float. There is no toxicity toward the plant though, only defense against the digestive action. Pitcher plants such as Sarracenia and Darlingtonia are Bottle traps Sticky Snares are usually hairs that have glands that produce a sticky, digestive substance. The hairs are often, but not always capable of moving to improve the success of the catch. To escape, your victim must be strong enough to pull out of the glue. Using some sort of chemical would be useless, unless it is capable of breaking down the glue. Sundews (Drosera) are common users of Sticky Snares, along with Butterworts (Pinguicula). Closing Boxes are traps that move quickly when they are stimulated by the presence of an animal. They generally have some trigger that sets them off, they trap the unfortunate, and then close more slowly to seal their fate. Venus Fly-trap has long trichomes that prevent escape after the first motion. To escape, you must either be strong enough to open the trap, or be able to chew your way out. To use chemistry, the trapped animal would have to produce some compound that reverses the action of the trap, or fools the trap into thinking that there is nothing there. Bladderworts (Utricularia) and Venus Fly-trap (Dionaea) use a Closing Box type of trap. Sean |
