Although hybrid crop varieties are among the most popular agricultural innovations, the
rationale for hybrid crop breeding is sometimes misunderstood. Hybrid breeding is slower …

Polyploidy, or whole genome multiplication, is ubiquitous among angiosperms. Many crop
species are relatively recent allopolyploids, resulting from interspecific hybridization and …

Hybrid maize displays superior heterosis and contributes over 30% of total worldwide cereal
production. However, the molecular mechanisms of heterosis remain obscure. Here we …

Networks are powerful tools to uncover functional roles of genes in phenotypic variation at a
system-wide scale. Here, we constructed a maize network map that contains the genomic …

Maize is a globally valuable commodity and one of the most extensively studied genetic
model organisms. However, we know surprisingly little about the extent and potential utility …

Since the development of single-hybrid maize breeding programs in the first half of the
twentieth century, maize yields have increased over sevenfold, and much of that increase …

Single-cross maize hybrids display superior heterosis and are produced from crossing two
parental inbred lines belonging to genetically different heterotic groups. Here we assembled …

Domesticated crops experience strong human-mediated selection aimed at developing high-
yielding varieties adapted to local conditions. To detect regions of the wheat genome subject …

Background Genotyping by sequencing, a new low-cost, high-throughput sequencing
technology was used to genotype 2,815 maize inbred accessions, preserved mostly at the …

The domestication and development of cattle has considerably impacted human societies,
but the histories of cattle breeds and populations have been poorly understood especially …
