全基因加倍/复制(whole genome duplication, WGD)或者多倍化(polyploidy)事件是指某物种通过染色体倍增的方式导致多套染色体共存于同一细胞核中,形成稳定遗传的新物种的现象。根据多倍化后染色体的演化状态,可将多倍体分为两类:古多倍体(paleo-polyploids)和新多倍体(neo-polyploids)。古多倍体物种是指经历多倍化事件的...
Whole genome duplication (WGD) is a major factor in evolution, adaptation and speciation. Yet by doubling the number of homologs present, WGD challenges reliable chromosome segregation, a process conserved across eukaryotes. Through its negative effects on chromosome segregation, WGD can contribute to ...

Whole-genome duplication (WGD), or polyploidy, events are widespread and significant in the evolutionary history of angiosperms. However, empirical evidence for rediploidization, the major process where polyploids give rise to diploid descendants, is still lacking at the genomic level. Here we prese...

Gene duplication, a major evolutionary path to genomic innovation, can occur at the scale of an entire genome. One such "whole-genome duplication" (WGD) event among the Ascomycota fungi gave rise to genes with distinct biological properties compared to s

Whole-genome duplication (WGD), or polyploidy, is a major force in plant genome evolution. A duplicate of all genes is present in the genome immediately following a WGD event. However, the evolutionary mechanisms responsible for the loss of, or retention and subsequent functional divergence of ...
