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 ...

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 ...

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 ...

A new study led by the Roslin Institute seeks to unlock the mysteries behind a powerful genetic phenomenon that has played a ...

A team at Washington University traced how plants gained duplicate DNA-control enzymes that evolved into new functions, boosting their ability to handle stress. The finding shows how a single genetic ...

Cold Spring Harbor, N.Y. – Before a cell can divide into two, first it must duplicate its genetic material--the DNA packed in its chromosomes. The two new sets of chromosomes then have to be separated ...

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 ...

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 ...
