Genome size evolution is a dynamic process involving counterbalancing mechanisms
whose actions vary across lineages and over time. Whereas the primary mechanism of …

Genome sizes vary by several orders of magnitude, driven by mechanisms such as
illegitimate recombination and transposable element proliferation. Prior analysis of the CesA …

Genome sizes in plants vary over several orders of magnitude, reflecting a combination of
differentially acting local and global forces such as biases in indel accumulation and …

Of the many processes that generate gene duplications, polyploidy is unique in that entire
genomes are duplicated. This process has been important in the evolution of many …

Genome duplication is thought to be central to the evolution of morphological complexity,
and some polyploids enjoy a variety of capabilities that transgress those of their diploid …

Background Modern allotetraploid cotton contains an “A” and “D” genome from an ancestral
polyploidy event that occurred approximately 1–2 million years ago. Diploid A-and D …

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

Polyploidy plays a major role in genome evolution, which corresponds to environmental
changes over millions of years. The mechanisms of genome evolution, particularly during …

Understanding the composition, evolution, and function of the Gossypium hirsutum (cotton)
genome is complicated by the joint presence of two genomes in its nucleus (AT and DT …

Transposable elements, particularly LTR-retrotransposons, comprise the primary vehicle for
genome size expansion in plants, while DNA removal through illegitimate recombination …
