Induction of tetraploidy in rainbow trout (Oncorhynchus mykiss) by heat shock [PDF]

, 2004
This study has been conducted for determination of optimum time and duration of thermal shock on tetraploidy induction in Rainbow trout. This study was carried out by induction of 28°C thermal shock in different times after fertilization (49.5, 54.0, 58 ...

DNA lesions induced by replication stress trigger mitotic aberration and tetraploidy development. [PDF]

PLoS ONE, 2010
During tumorigenesis, cells acquire immortality in association with the development of genomic instability. However, it is still elusive how genomic instability spontaneously generates during the process of tumorigenesis.

The role of DNA content in shaping chromatin architecture and gene expression

The Plant Journal, Volume 121, Issue 6, March 2025.
SUMMARY Whole‐genome duplication is an evolutionary force that drives speciation in all living kingdoms and is notably prevalent in plants. The evolutionary history of plants involved at least two genomic duplications that significantly expanded the plant morphology and physiology spectrum. Many important crops are polyploids, showing valuable features

Variations in morphological, biochemical and phytochemical traits of diploid and induced tetraploid plants of downy thorn-apple (Datura innoxia Mill.)

Journal of Medicinal Plants, 2022
Background: Datura species produce a wide range of tropane alkaloids with medicinal values. D. innoxia is a species of the Datura genus which is poisonous and has an unpleasant odor due to the presence of tropane alkaloids.

Experimental Evolution Reveals Interplay between Sch9 and Polyploid Stability in Yeast. [PDF]

PLoS Genetics, 2016
Polyploidization has crucial impacts on the evolution of different eukaryotic lineages including fungi, plants and animals. Recent genome data suggest that, for many polyploidization events, all duplicated chromosomes are maintained and genome ...

Convergent Patterns of Karyotype Evolution Underlying Karyotype Uniformity in Conifers

Advanced Science, Volume 12, Issue 7, February 17, 2025.
The remarkable karyotype uniformity observed in gymnosperms has long posed an evolutionary puzzle. This study proposes a model of karyotype evolution in gymnosperms, highlighting the rarity of both polyploidy and dysploidy as key factors underlying this uniformity.

Genomic instability in human cancer: molecular insights and opportunities for therapeutic attack and prevention through diet and nutrition [PDF]

, 2015
Genomic instability can initiate cancer, augment progression, and influence the overall prognosis of the affected patient. Genomic instability arises from many different pathways, such as telomere damage, centrosome amplification, epigenetic ...

The Induction of Tetraploidy in Salmonids

Journal of the World Aquaculture Society, 1986
AbstractThe induction of tetraploidy was attempted in three intraspecies crosses (autotetraploid) of sal‐monid: chinook salmon (Oncorhynchus tshawytscha), coho salmon (O. kisutch) and rainbow trout (Salmo gairdneri), and in the interspecies hybrid (allotetraploid) coho × Atlantic salmon (Salmo salar).Pressure treatments of 6.2 × 104 kPa (9,000 psi ...
