National Institutes of Health researchers have identified a gene that makes yeast resistant to a lethal toxin, according to a new study published in the Proceedings of the National Academy of Sciences. To study the evolution of toxin resistance, researchers at the National Human Genome Research Institute (NHGRI), part of NIH, used yeast—the kind commonly used for home baking—as a model organism. While researchers have long known about yeast’s remarkable ability to evade the effects of lethal toxins, the reason was a mystery until now. Read More
