Insights into the rice and Arabidopsis genomes: intron fates, paralogs, and lineage-specific genes
… expression profile datasets, we examined</p> <p>segmental duplication, intron turnover, and paralogous protein family</p> <p>composition in rice. These data suggest a large percentage of the rice genome</p> <p>was involved in segmental duplication creating a large number of paralogous</p> …

Unsupervised Learning : Model-guided and Model-agnostic Approaches
… to a specific phenomenon in genomics, known as segmental duplication. The problem can be formulated as either a (a) low-rank matrix completion or a (b) robust signed community detection based on suitable assumptions on the data. We design algorithms for resolving segmental duplication in genomes …

Sequence of the mouse Y chromosome
… mouse Y chromosome is made up of a single 92 Mb segmental duplication that we have named the Huge Repeat array. The Huge Repeat array is a collection of 150-200 515 kb repeat units. The repeat units are internally repetitive, gene-containing, and have a repeat unit to repeat unit similarity …

Organ-specific regulation and molecular evolution of the maize pericarp color1 gene
… novel cis-regulatory regions. Because tandem and segmental duplication are common in both animal and plant genomes, homologous recombination between non-coding duplicated sequences could have been an important means to generate genetic and phenotypic variations.</p>

Identification and annotation of recombinant repeats in mammals indicates they are experimental products for creating novel transposable element families.
… they contained polyA tails and target site duplications, showing that they integrated into the genome via retrotransposition events. However, complex recombinant repeat families were only replicated via segmental duplications. My analysis showed that complex recombinant repeat families are …

Transcription of human-specific duplicate genes
… interest in these genes is twofold: First, gene duplication is a fundamental process by which evolutionary innovations at the organismal level arise; and second, we believe that variation in these new genes is an important and unappreciated source of phenotypic differences between individuals, …

Analysis of the antifreeze glycoprotein containing genomic locus in the Antarctic notothenioid fish dissostichus mawsoni
… in haplotype 2) that very likely resulted from segmental duplications of the AFGP gene and its flanking regions, as seen in the >95 % sequence identity between AFGP gene modules. Thus it is clear that extensive AFGP gene duplication resulting in high gene dosage is the molecular basis for the …

Creating sense from non-sense DNA: de novo genesis and evolutionary history of antifreeze glycoprotein gene in northern cod fishes (gadidae)
… cds, which supports the hypothesis that de novo duplication of the 9-nt element in the middle created the repetitive AFGP cds. Comparison of these AFGPs with non-coding AFGP homologous sequences in three gadid species that lack AFGP reveals that a putative promoter region was only present in the …
