Ancient duplication events and a high rate of retention of extant pairs of duplicate genes
have contributed to an abundance of duplicate genes in plant genomes. These duplicates …

Whole-genome duplication (WGD) is characteristic of almost all fundamental lineages of
land plants. Unfortunately, the timings of WGD events are loosely constrained and …

Animal genomes show networks of deeply conserved gene linkages whose phylogenetic
scope and chromosomal context remain unclear. Here, we report chromosome-scale …

Gene duplications have long been recognized as a contributor to the evolution of genes with
new functions. Multiple copies of genes can result from tandem duplication, from …

Polyploidy is an evolutionary innovation for many animals and all flowering plants, but its
impact on selection and domestication remains elusive. Here we analyze genome evolution …

Adaptive changes in plant phenology are often considered to be a feature of the so-called
'domestication syndrome'that distinguishes modern crops from their wild progenitors, but …

Background The sharp increase of plant genome and transcriptome data provide valuable
resources to investigate evolutionary consequences of gene duplication in a range of taxa …

Understanding why some evolutionary lineages generate exceptionally high species
diversity is an important goal in evolutionary biology. Haplochromine cichlid fishes of Africa's …

Chenopodium quinoa (quinoa) is a highly nutritious grain identified as an important crop to
improve world food security. Unfortunately, few resources are available to facilitate its …

Ancient whole-genome duplications (WGDs or polyploidy) are prevalent in plants, and some
WGDs occurred during the timing of severe global environmental changes. It has been …
