Plants tend to hoard DNA, not throwing anything out. The extra genes they hold inside can mutate to produce new physical traits. Holding onto the extra genes increases the tempo of evolution for the ...

Biologists at Washington University in St. Louis have discovered the origin of a curious duplication that gives plants multiple ways to override instructions that are coded into their DNA. This ...

A new study shows that DNA duplication has been vitally important throughout the evolutionary history of gymnosperms, a diverse group of seed plants that includes pines, cypresses, sequoias, ginkgos ...

A new, large-scale analysis of the relationships among members of the largest subfamily of grasses, which includes wheat and barley, reveals gene-duplication events that contributed to the adaptation ...

New research shows genome duplication in the ancestor of modern gymnosperms, a group of seed plants that includes cypresses and pines, might have directly contributed to the origin of the group over ...

Researchers at USC have developed a yeast model to study a gene mutation that disrupts the duplication of DNA, causing massive damage to a cell's chromosomes, while somehow allowing the cell to ...

GAINESVILLE, Fla. --- Plants are DNA hoarders. Adhering to the maxim of never throwing anything out that might be useful later, they often duplicate their entire genome and hang on to the added ...
