Heritable variation in gene expression is common within and between species. This
variation arises from mutations that alter the form or function of molecular gene regulatory …

There is abundant variation in gene expression between individuals, populations, and
species. The evolution of gene regulation and expression within and between species is …

From its tropical origin in southwestern Mexico, maize spread over a wide latitudinal cline in
the Americas. This feat defies the rule that crops are inhibited from spreading easily across …

The polymerase chain reaction (PCR) has matured from a labour-and time-intensive, low
throughput qualitative gel-based technique to an easily automated, rapid, high throughput …

Utilization of heterosis has greatly increased the productivity of many crops worldwide.
Although tremendous progress has been made in characterizing the genetic basis of …

During evolution, novel phenotypes emerge through changes in gene expression, but the
genetic basis is poorly understood. We compared the allele-specific expression of two yeast …

Allele‐specific expression (ASE) can lead to phenotypic diversity and evolution. However,
the mechanisms regulating ASE are not well understood, particularly in woody perennial …

Polyploidy is an important force in the evolution of flowering plants. Genomic merger and
doubling induce an extensive array of genomic effects, including immediate and long-term …

Typically, F1-hybrids are more vigorous than their homozygous, genetically distinct parents,
a phenomenon known as heterosis. In the present study, the transcriptomes of the reciprocal …

Gene expression differences between divergent lineages caused by modification of cis
regulatory elements are thought to be important in evolution. We assayed genome-wide cis …
