Global analysis of the small RNA transcriptome in different ploidies and genomic combinations of a vertebrate complex--the Squalius alburnoides. [PDF]

PLoS ONE, 2012
The Squalius alburnoides complex (Steindachner) is one of the most intricate hybrid polyploid systems known in vertebrates. In this complex, the constant switch of the genome composition in consecutive generations, very frequently involving a change on ...

Karyotypic determinants of chromosome instability in aneuploid budding yeast. [PDF]

PLoS Genetics, 2012
Recent studies in cancer cells and budding yeast demonstrated that aneuploidy, the state of having abnormal chromosome numbers, correlates with elevated chromosome instability (CIN), i.e.

Characterization of Repetitive DNA in Saccharum officinarum and Saccharum spontaneum by Genome Sequencing and Cytological Assays

Frontiers in Plant Science, 2022
In most plant species, DNA repeated elements such as satellites and retrotransposons are composing the majority of their genomes. Saccharum officinarum (2n = 8x = 80) and S.

The Analysis of Short-Term Differential Expression of Transcription Factor Family Genes in Diploid and Tetraploid Rice (Oryza sativa L.) Varieties during Blast Fungus Infection

Agronomy, 2023
The necessity to understand plant adaptations to environmental stressors is underscored by the role of polyploidy in species evolution. This study focuses on the superior stress resistance exhibited by autotetraploid rice, which arises from chromosome ...

The Effect of Triploidy on Gonadal Development, Hematology and Biochemistry in the European Grayling (Thymallus thymallus). [PDF]

Animals (Basel)
Sterile triploid European graylings (Thymallus thymallus) could serve as an alternative to allochthonous stocking, potentially protecting native populations from genetic introgression.

Energetic budget of diploid and triploid eastern oysters during a summer die-off

Frontiers in Marine Science, 2023
Triploid oysters are widely used in off-bottom aquaculture of eastern oysters, Crassostrea virginica. However, farmers of the Gulf of Mexico (GoM) and Atlantic coast estuaries have observed unresolved, late-spring die-offs of triploid oysters ...

A comparative analysis of DNA methylation in diploid and tetraploid apple (Malus × domestica Borkh.)

Czech Journal of Genetics and Plant Breeding, 2017
DNA methylation is one of the major epigenetic modifications. It is very important to the regulation of gene expression. Methylation-sensitive amplification polymorphism (MSAP) profiling was applied to a diploid apple cultivar and its derived ...

Use of natural trophic resources by Eastern oysters and Pacific oysters of different ploidy

Aquaculture and Fisheries, 2021
Ploidy manipulation, such as triploidy, in farmed oysters has been used as a tool to enhance oyster quality throughout all seasons because triploid oysters allocate less energy to gametogenesis, and therefore are deemed better performers than fertile ...

A seasonal study on the microbiomes of Diploid vs. Triploid eastern oysters and their denitrification potential

iScience
Summary: Oyster reefs are hotspots of denitrification mediated removal of dissolved nitrogen (N), however, information on their denitrifier microbiota is scarce.

Frequencies and variation in cytosine methylation patterns in diploid and tetraploid cytotypes of Paspalum notatum

Biologia Plantarum, 2012
Paspalum notatum Flügge is a grass species organized as an agamic complex. The objective of the current research was to survey the frequencies and variation of cytosine methylation at CCGG sequences in diploid and tetraploid genotypes, and to determine ...
