Polyploidy and whole genome duplication (WGD) are widespread biological phenomena with substantial cellular, meiotic, and genetic effects. Despite their prevalence and significance across the tree of ...

Researchers pinpoint the genes responsible for the final three pea traits studied by the famed citizen scientist.

TO THE AMERICAN PEOPLE We all rely on science. Science gave us the smartphones in our pockets, the navigation systems in our cars, and life-saving medical care. We count on engineers when we drive acr...

After an extensive international search, the Donald Danforth Plant Science Center has named Giles Oldroyd, PhD, as its next President.

Domestication is a process marked by complex interactions between demographic changes and selective pressures, which together shape genetic diversity. While the phenotypic outcomes of domestication ar...

The current “consensus” order in which amino acids were added to the genetic code is based on potentially biased criteria, such as the absence of s...

Abstract Despite newly formed polyploids being subjected to myriad fitness consequences, the relative prevalence of polyploidy, both contemporarily and in ancestral branches of the tree of life, sugge...

Adaptation to novel environments requires genetic variation, which may either predate the novel environment or arise as new mutations. The relative importance of standing genetic variation vs. de novo...

Three cross-incompatibility loci each control a distinct reproductive barrier in domesticated maize ( Zea mays ssp. mays ) and its wild teosinte relatives. These three loci, Teosinte crossing barrier ...
