Crop genomics has seen dramatic advances in recent years due to improvements in
sequencing technology, assembly methods, and computational resources. These advances …

Mixed-ploidy species harbor a unique form of genomic and phenotypic variation that
influences ecological interactions, facilitates genetic divergence, and offers insights into the …

A goal of evolutionary biology is to understand the roles of geography and ecology in
speciation. The recent shared ancestry of sister species can leave a major imprint on their …

Allopolyploids result from hybridization between different evolutionary lineages coupled with
genome doubling. Homoeologous chromosomes (chromosomes with common shared …

Root-knot nematodes (genus Meloidogyne) exhibit a diversity of reproductive modes
ranging from obligatory sexual to fully asexual reproduction. Intriguingly, the most …

Many previous studies have provided evidence for genome changes in polyploids, but there
are little data on the overall population dynamics of genome change and whether it causes …

Speciation is characterized by the evolution of reproductive isolation between two groups of
organisms. Understanding the process of speciation requires the quantification of barriers to …

Though polyploidy is an important aspect of the evolutionary genetics of both plants and
animals, the development of population genetic theory of polyploids has seriously lagged …

A large number of mathematical models have been developed that show how natural and
sexual selection can cause prezygotic isolation to evolve. This article attempts to unify this …

The wheat group has evolved through allopolyploidization, namely, through hybridization
among species from the plant genera Aegilops and Triticum followed by genome doubling …
