TL;DR: Single-nucleotide polymorphism genotyping and data on numerous environmental variables are used to describe the genetic basis of local adaptation in 21 populations of teosinte, the wild ancestor of maize, to find complex hierarchical genetic structure created by altitude, dispersal events, and admixture among subspecies.

TL;DR: Results provide empirical support for an important role for incomplete dominance of deleterious alleles in explaining heterosis and demonstrate the utility of incorporating functional annotation in phenotypic prediction and plant breeding.

TL;DR: This paper used genome-wide genotyping data to characterize deleterious variants in a large panel of maize inbred lines and found that genes associated with a number of complex traits are enriched for deleterius variants.

TL;DR: Results provide strong empirical support for an important role for incomplete dominance of deleterious alleles in explaining heterosis and demonstrate the utility of incorporating functional annotation in phenotypic prediction and plant breeding.

TL;DR: In this article, the authors used high-density genotype data to describe the genetic basis of local adaptation in 21 populations of teosinte, the wild ancestor of maize, and found that altitude, dispersal events and admixture among subspecies formed a complex hierarchical genetic structure within teopsinte.
