Importance of gene duplication in the evolution of genomic imprinting revealed by molecular evolutionary analysis of the type I MADS-box gene family in Arabidopsis species. [PDF]
PLoS ONE, 2013 The pattern of molecular evolution of imprinted genes is controversial and the entire picture is still to be unveiled. Recently, a relationship between the formation of imprinted genes and gene duplication was reported in genome-wide survey of imprinted ...

Tandem duplications and the limits of natural selection in Drosophila yakuba and Drosophila simulans [PDF]
, 2014 Tandem duplications are an essential source of genetic novelty, and their variation in natural populations is expected to influence adaptive walks. Here, we describe evolutionary impacts of recently-derived, segregating tandem duplications in Drosophila yakuba and Drosophila simulans. We observe an excess of duplicated genes involved in defense against

Duplication processes in Saccharomyces cerevisiae haploid strains [PDF]
, 2005 Duplication is thought to be one of the main processes providing a substrate on which the effects of evolution are visible. The mechanisms underlying this chromosomal rearrangement were investigated here in the yeast Saccharomyces cerevisiae. Spontaneous

Landscape of standing variation for tandem duplications in Drosophila yakuba and Drosophila simulans [PDF]
, 2014 We have used whole genome paired-end Illumina sequence data to identify tandem duplications in 20 isofemale lines of D. yakuba, and 20 isofemale lines of D. simulans and performed genome wide validation with PacBio long molecule sequencing. We identify 1,415 tandem duplications that are segregating in D.

The divergence of alternative splicing between ohnologs in teleost fishes
BMC Ecology and Evolution, 2021 Background Gene duplication and alternative splicing (AS) are two distinct mechanisms generating new materials for genetic innovations. The evolutionary link between gene duplication and AS is still controversial, due to utilizing duplicates from ...

Nonrandom divergence of gene expression following gene and genome duplications in the flowering plant Arabidopsis thaliana [PDF]
, 2006 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 genome-wide duplication events. Recently, we have shown that gene loss is strikingly

Duplication and expression of Sox genes in spiders [PDF]
BMC Evolutionary Biology, 2018 BACKGROUND: The Sox family of transcription factors is an important part of the genetic 'toolbox' of all metazoans examined to date and is known to play important developmental roles in vertebrates and insects. However, outside the commonly studied Drosophila model little is known about the repertoire of Sox family transcription factors in other ...

Partial duplication of the APBA2 gene in chromosome 15q13 corresponds to duplicon structures. [PDF]
, 2003 BackgroundChromosomal abnormalities affecting human chromosome 15q11-q13 underlie multiple genomic disorders caused by deletion, duplication and triplication of intervals in this region.
