Genetic variation, which is generated by mutation, recombination and gene flow, can reduce
the mean fitness of a population, both now and in the future. This 'genetic load'has been …

Over two thousand plant species have been modified morphologically through cultivation
and human use. Here, we review three aspects of crop domestication that are currently …

Hybrid potato breeding will transform the crop from a clonally propagated tetraploid to a
seed-reproducing diploid. Historical accumulation of deleterious mutations in potato …

The “cost of domestication” hypothesis posits that the process of domesticating wild species
can result in an increase in the number, frequency, and/or proportion of deleterious genetic …

Globally, soybean is a major protein and oil crop. Enhancing our understanding of the
soybean domestication and improvement process helps boost genomics-assisted breeding …

Mutations with deleterious consequences in nature may be conditionally deleterious in crop
plants. That is, while some genetic variants may reduce fitness under wild conditions and be …

Here, we describe a worldwide haplotype map for soybean (GmHapMap) constructed using
whole‐genome sequence data for 1007 Glycine max accessions and yielding 14.9 million …

Predicting fitness in natural populations is a major challenge in biology. It may be possible to
leverage fast-accumulating genomic data sets to infer the fitness effects of mutant alleles …

Whole-genome duplication (polyploidization) is among the most dramatic mutational
processes in nature, so understanding how natural selection differs in polyploids relative to …

In grafted plants, such as grapevine, increasing the diversity of rootstocks available to
growers is an ideal strategy for helping plants to adapt to climate change. The rootstocks …
