The evolution of genes and genomes after polyploidization has been the subject of
extensive studies in evolutionary biology and plant sciences. While a significant number of …

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 …

Episodes of whole-genome duplication (WGD) followed by gene loss dominate the
evolutionary history of flowering plants. Despite the importance of understanding gene …

Gene duplication, arising from region-specific duplication or genome-wide polyploidization,
is a prominent feature in plant genome evolution. Understanding the mechanisms …

Ancient duplication events and a high rate of retention of extant pairs of duplicate genes
have contributed to an abundance of duplicate genes in plant genomes. These duplicates …

For most sequenced flowering plants, multiple whole-genome duplications (WGDs) are
found. Duplicated genes following WGD often have different fates that can quickly disappear …

Background All extant seed plants are successful paleopolyploids, whose genomes carry
duplicate genes that have survived repeated episodes of diploidization. However, the …

Gene duplication is a primary means to generate genomic novelties, playing an essential
role in speciation and adaptation. Particularly in plants, a high abundance of duplicate …

Background Gene duplication has played an important role in the evolution and
domestication of flowering plants. Yet little is known about how plant duplicate genes evolve …

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 …
