Ancient tetraploidies are found throughout the eukaryotes. After duplication, one copy of
each duplicate gene pair tends to be lost (fractionate). For all studied tetraploidies, the loss …

The maize genome experienced an ancient whole genome duplication∼ 10 MYA and the
duplicate subgenomes have since experienced reciprocal gene loss such that many genes …

Polyploidy is an important feature of plant genomes, but the nature of many polyploidization
events remains to be elucidated. Here, we demonstrate that the evolutionary fates of the …

With a size approximating that of the human genome, the maize genome is about to become
the largest plant genome yet sequenced. Contributing to that size are a whole-genome …

Not all genes are created equal. Despite being supported by sequence conservation and
expression data, knockout homozygotes of many genes show no visible effects, at least …

Over the past 10 000 years, man has used the rich genetic diversity of the maize genome as
the raw material for domestication and subsequent crop improvement. Recent research …

Cellular processes mediated through nuclear DNA must contend with chromatin. Chromatin
structural assays can efficiently integrate information across diverse regulatory elements …

Maize is one of the world's highest value crops, with a multibillion dollar annual contribution
to agriculture. The great adaptability and high yields available for maize as a food, feed and …

Previous work in Arabidopsis showed that after an ancient tetraploidy event, genes were
preferentially removed from one of the two homeologs, a process known as fractionation …

Maize (Zea mays L. ssp. mays), one of the most important agricultural crops in the world,
originated by hybridization of two closely related progenitors. To investigate the fate of its …
