Cytogenetics and Consequences of Polyploidization on Different Biotic-Abiotic Stress Tolerance and the Potential Mechanisms Involved

open access: yesPlants, 2022
The application of polyploidy in sustainable agriculture has already brought much appreciation among researchers. Polyploidy may occur naturally or can be induced in the laboratory using chemical or gaseous agents and results in complete chromosome ...

Polyploidization in Orchids: From Cellular Changes to Breeding Applications

open access: yesPlants, 2022
Polyploidy occurs naturally in plants through cell division errors or can artificially be induced by antimitotic agents and has ecological effects on species adaptation, evolution, and development.

A role for polyploidy in the tumorigenicity of Pim-1-expressing human prostate and mammary epithelial cells. [PDF]

open access: yesPLoS ONE, 2008
BackgroundPolyploidy is a prominent feature of many human cancers, and it has long been hypothesized that polyploidy may contribute to tumorigenesis by promoting genomic instability.

The Influence of Geographical Factors on Polyploidy in Angiosperms with Cartographic Evidence from the Northwestern Himalayas: A Review [PDF]

open access: yesNature Environment and Pollution Technology, 2023
The review paper comprised the impact of geographical and environmental factors on polyploidy and vice versa. The review covers different effects of geographical factors, like spatial isolation, altitude, and local climate on polyploidy, and the behavior

Evolutionary and Genomic Diversity of True Polyploidy in Tetrapods

open access: yesAnimals, 2023
True polyploid organisms have more than two chromosome sets in their somatic and germline cells. Polyploidy is a major evolutionary force and has played a significant role in the early genomic evolution of plants, different invertebrate taxa, chordates ...

POInTbrowse: orthology prediction and synteny exploration for paleopolyploid genomes

open access: yesBMC Bioinformatics, 2023
We describe POInTbrowse, a web portal that gives access to the orthology inferences made for polyploid genomes with POInT, the Polyploidy Orthology Inference Tool.

The influence of experimentally induced polyploidy on the relationships between endopolyploidy and plant function in Arabidopsis thaliana

open access: yesEcology and Evolution, 2020
Whole genome duplication, leading to polyploidy and endopolyploidy, occurs in all domains and kingdoms and is especially prevalent in vascular plants. Both polyploidy and endopolyploidy increase cell size, but it is unclear whether both processes have ...

Polyploidy did not predate the evolution of nodulation in all legumes. [PDF]

open access: yesPLoS ONE, 2010
BACKGROUND: Several lines of evidence indicate that polyploidy occurred by around 54 million years ago, early in the history of legume evolution, but it has not been known whether this event was confined to the papilionoid subfamily (Papilionoideae; e.g.

A Reappraisal of Polyploidy Events in Grasses (Poaceae) in a Rapidly Changing World

open access: yesBiology, 2022
Around 80% of megaflora species became extinct at the Cretaceous–Paleogene (K–Pg) boundary. Subsequent polyploidy events drove the survival of thousands of plant species and played a significant historical role in the development of the most successful ...

The role of cellular polyploidy in the regeneration of the cirrhotic liver in rats and humans [PDF]

open access: yesComparative Cytogenetics
Polyploidy is a condition in which a cell has multiple diploid sets of chromosomes. Two forms of polyploidy are known. One of them, generative polyploidy, is characteristic of all cells of the organism, while the other form develops only in some somatic ...
