De novo genome assembly of the cichlid fish Astatotilapia latifasciata reveals a higher level of genomic polymorphism and genes related to B chromosomes
(2019-01-01)
Supernumerary B chromosomes (Bs) are accessory elements to the regular chromosome set (As) and have been observed in a huge diversity of eukaryotic species. Although extensively investigated, the biological significance ...
Chromosomal copy number variation reveals differential levels of genomic plasticity in distinct Trypanosoma cruzi strains
(BioMed Central, 2015)
Background: Trypanosoma cruzi, the etiologic agent of Chagas disease, is currently divided into six discrete typing units (DTUs), named TcI-TcVI. CL Brener, the reference strain of the T. cruzi genome project, is a hybrid ...
Chromosome-Level Genome Assembly of the Blue Mussel Mytilus chilensis Reveals Molecular Signatures Facing the Marine Environment
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-04)
The blue mussel Mytilus chilensis is an endemic and key socioeconomic species inhabiting the southern coast of Chile. This bivalve species supports a booming aquaculture industry, which entirely relies on artificially ...
Complete Chromosome-scale genome sequence resource for sporisorium panici-leucophaei, the causal agent of sourgrass smut disease
(2021-04-01)
Here, we present the first complete chromosome-level genome assembly of the smut fungus strain Sporisorium panici-leucophaei SPL10A, the causal agent of the sourgrass (Digitaria insularis) smut disease. Combining Illumina ...
Chromosomal Instability in Mouse Embryonic Fibroblasts Null for the Transcriptional Co-Repressor Ski
(WILEY-BLACKWELL, 2012-01)
Ski is a transcriptional regulator that has been considered an oncoprotein given its ability to induce oncogenic transformation in avian model systems. However, studies in mouse and in some human tumor cells have also ...
Long-term persistence of supernumerary B chromosomes in multiple species of Astyanax fish
(2021-12-01)
Background: Eukaryote genomes frequently harbor supernumerary B chromosomes in addition to the “standard” A chromosome set. B chromosomes are thought to arise as byproducts of genome rearrangements and have mostly been ...
Chromosome-Level Genome Reveals the Origin of Neo-Y Chromosome in the Male Barred Knifejaw Oplegnathus fasciatus
(Elsevier Inc., 2020-04-24)
The barred knifejaw, Oplegnathus fasciatus, is characterized by an X1X2Y system with a neo-Y chromosome for males. Here, a chromosome-level genome was assembled to investigate the origin of neo-Y chromosome to the male O. ...
Characterization of the repetitive DNA landscape in wheat homeologous group 4 chromosomes
(2015)
Background:
The number and complexity of repetitive elements varies between species, being in general most represented in those with larger genomes. Combining the flow-sorted chromosome arms approach to genome analysis ...
Further evidence of chromosome abnormalities in normal and haploid gynogenetic progenies of rainbow trout, oncorhynchus mykiss
(WILEY-LISS, 1996)
A molecular characterization of tubulin and microtubule-associated proteins (MAPs) along with their intracellular pool distributions in both unfertilized and fertilized oocytes of the trout Oncorhynchus mykiss was carried ...
