Domestication and plant breeding are ongoing 10,000-year-old evolutionary experiments
that have radically altered wild species to meet human needs. Maize has undergone a …

Identifying mechanisms of tolerance to herbivore damage will facilitate attempts to understand
the role of tolerance in the evolutionary and ecological dynamics of plants and herbivores. …

Local adaptation shapes species diversity, can be a stepping stone to ecological speciation,
and can facilitate species range expansion. Population genetic analyses, which …

Patterns of reproductive isolation between species may provide insight into the mechanisms
and evolution of barriers to interspecific gene exchange. We used data from published …

Individuals of the same species are generally thought to have very similar genomes. However,
there is growing evidence that structural variation in the form of copy number variation (…

DNA methylation is a chromatin modification that is frequently associated with epigenetic
regulation in plants and mammals. However, genetic changes such as transposon insertions …

Medicago truncatula is a model for investigating legume genetics, including the genetics and
evolution of legume–rhizobia symbiosis. We used whole-genome sequence data to identify …

Several mechanisms are expected to rapidly rid mutualisms of genetic variation in partner
quality. Variation for mutualist quality, however, appears to be widespread. We used a model …

Analyses among animal species have found that reproductive isolation increases monotonically
with genetic distance, evolves more quickly for prezygotic than postzygotic traits, and is …

The anthocyanin biosynthetic pathway is responsible for the production of anthocyanin pigments
in plant tissues and shares a number of enzymes with other biochemical pathways. The …
