Previous work in Arabidopsis showed that after an ancient tetraploidy event, genes were
preferentially removed from one of the two homeologs, a process known as fractionation …

Polyploidy is an important feature of plant genomes, but the nature of many polyploidization
events remains to be elucidated. Here, we demonstrate that the evolutionary fates of the …

Modern plant genomes are diploidized paleopolyploids. We revisited grass genome
paleohistory in response to the diploidization process through a detailed investigation of the …

Unlike in mammals, plants rapidly delete functionless, nonrepetitive DNA from their
genomes. Following paleopolyploidies, duplicate genes are deleted by intrachromosomal …

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 …

A phylogenetic tree can be used to illustrate the evolutionary relationship between a group
of genes, especially duplicated genes, which are sources of genetic innovation and are …

Both ancient and recent polyploidy, together with post-polyploidization loss of many
duplicated gene copies, complicates angiosperm comparative genomics. To explore an …

Most eukaryotes have genomes that exhibit high levels of gene redundancy, much of which
seems to have arisen from one or more cycles of genome doubling. Polyploidy has been …

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

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