Scientists uncover key mechanism in evolution: Whole-genome duplication drives long-term adaptation
Sometimes, the most significant scientific discoveries happen by accident. Scientists have long known that whole-genome duplication (WGD)—the process by which organisms copy all their genetic material—plays an important role in evolution. But understanding just how WGD arises, persists, and drives adaptation has remained poorly understood.
Mapping the yerba mate genome reveals surprising facts about the evolution of caffeine
Yerba mate, along with tea and coffee, is one of the world's most popular caffeinated beverages. Widely consumed in South America, this remarkable plant is rich in diverse, bioactive compounds that contribute many health benefits.
The effects of whole genome duplication on the plant metabolome
Whole genome duplication (WGD) is a common mutation in plants with profound evolutionary potential. While it is well-known that an increase in genetic material can lead to larger cell sizes, the impact of gene dosage multiplication on the metabolome remains largely unexplored.
Geneticists discover hidden 'whole genome duplication' that may explain why some species survived mass extinctions
Geneticists have unearthed a major event in the ancient history of sturgeons and paddlefish that has significant implications for the way we understand evolution. They have pinpointed a previously hidden "whole genome duplication" (WGD) in the common ancestor of these species, which seemingly opened the door to genetic variations that may have conferred an advantage around the time of a major mass extinction some 200 million years ago.
