Genetic architecture refers to the numbers and genome locations of genes that affect a trait,
the magnitude of their effects, and the relative contributions of additive, dominant, and …

One-third of the planet's arable land has been lost to soil erosion in recent decades, …

… gene increases the selection pressure for virulence in pathogen populations, which could
lead to rapid spread of pathogen types able to overcome the resistance gene (Holland 2001a). …

As population structure can result in spurious associations, it has constrained the use of
association studies in human and plant genetics. Association mapping, however, holds great …

Flowering time is a complex trait that controls adaptation of plants to their local environment
in the outcrossing species Zea mays (maize). We dissected variation for flowering time with a …

We investigated the genetic and statistical properties of the nested association mapping (NAM)
design currently being implemented in maize (26 diverse founders and 5000 distinct …

Maize genetic diversity has been used to understand the molecular basis of phenotypic
variation and to improve agricultural efficiency and sustainability. We crossed 25 diverse inbred …

Heritability was originally defined by Lush as the proportion of phenotypic variance among
individuals in a population that is due to heritable genetic effects (Nyquist 1991, p. 248). This …

US maize yield has increased eight-fold in the past 80 years, with half of the gain attributed
to selection by breeders. During this time, changes in maize leaf angle and size have altered …

Nested association mapping (NAM) offers power to resolve complex, quantitative traits to
their causal loci. The maize NAM population, consisting of 5,000 recombinant inbred lines (RILs…
