The importance of gene gain through duplication has long been appreciated. In contrast, the
importance of gene loss has only recently attracted attention. Indeed, studies in organisms …

Genome duplication is potentially a good source of new genes, but such genes take time to
evolve. We have found a group of 'duplication-resistant'genes, which have undergone …

Gene duplication is an important mechanism for adding to genomic novelty. Hence, which
genes undergo duplication and are preserved following duplication is an important question …

Background Genome analyses have revealed that gene duplication in plants is rampant.
Furthermore, many of the duplicated genes seem to have been created through ancient …

Given the prevalence of duplicate genes and genomes in plant species, the study of their
evolutionary dynamics has been a focus of study in plant evolutionary genetics over the past …

Genome duplication followed by massive gene loss has permanently shaped the genomes
of many higher eukaryotes, particularly angiosperms. It has long been believed that a …

Gene duplication is an important mechanism for acquiring new genes and creating genetic
novelty in organisms. Many new gene functions have evolved through gene duplication and …

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 …

Genome doubling (polyploidy) has been and continues to be a pervasive force in plant
evolution. Modern plant genomes harbor evidence of multiple rounds of past …

Gene duplications provide evolutionary potentials for generating novel functions, while
polyploidization or whole genome duplication (WGD) doubles the chromosomes initially and …
