Bt Toxin Resistance from Loss of a Putative Carbohydrate-Modifying

Enzyme

This study is telling one is science speak that toxins affect the way

an organism processes carbohydrates

The damage being done is to not inform people that their environment

is getting more and more toxic and that the effects are reversible.

All I want is people to know that they can improve their health

thereby improving cognition, nothing else no fighting. No anger But

truth and science and taking responsibility for the environment and

it's effect on us when we don't. As I stated I like the way my brain

works just fine, and maybe this info isn't for anyone and when I said

I was a researcher I was serious. not of glam mags but science. I

am aware that I am being wordy and I am unsure why I am responding

this way I guess I want people to know I am serious and committed. I

am trying to be part of all of the solution based science from Better

school programs to better nutrition. not in an effort to cure but in

an effort to reveal what intelligence is there and possible minus

toxins. I also apologise. I will not post on this topic as I have

again. mimi

The development of resistance is the main threat to the long-term use

of toxins from Bacillus thuringiensis (Bt) in transgenic plants. Here

we report the cloning of a Bt toxin resistance gene, Caenorhabditis

elegans bre-5, which encodes a putative -1,3-galactosyltransferase.

Lack of bre-5 in the intestine led to resistance to the Bt toxin

Cry5B. Wild-type but not bre-5 mutant animals were found to uptake

toxin into their gut cells, consistent with bre-5 mutants lacking

toxin-binding sites on their apical gut. bre-5 mutants displayed

resistance to Cry14A, a Bt toxin lethal to both nematodes and

insects; this indicates that resistance by loss of carbohydrate

modification is relevant to multiple Bt toxins.
