Polyploidy [PDF]

open access: yesCurrent Biology, 2015
Polyploidy is defined as an increase in genome DNA content. Throughout the plant and animal kingdoms specific cell types become polyploid as part of their differentiation programs. When this occurs in subsets of tissues within an organism it is termed somatic polyploidy, because it is distinct from the increase in ploidy that is inherited through the ...

Evolutionary and Genomic Diversity of True Polyploidy in Tetrapods [PDF]

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 ...

Focus on polyploidy [PDF]

open access: yesNew Phytologist, 2010
Polyploidy (whole-genome duplication) has played a pervasive role in the evolution of fungi and animals, and is particularly prominent in plants (Wendel & Doyle, 2005; Cui et al., 2006; Otto, 2007; Wood et al., 2009). This important evolutionary phenomenon has attracted renewed and growing interest from the scientific community in the last decade since

Polyploidy Index and Its Implications for the Evolution of Polyploids

open access: yesFrontiers in Genetics, 2019
Polyploidy has contributed to the divergence and domestication of plants; however, estimation of the relative roles that different types of polyploidy have played during evolution has been difficult.

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 ...

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.

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.

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

Polyploidy in Amphibia [PDF]

open access: yesCytogenetic and Genome Research, 2015
This review summarizes the current status of the known extant genuine polyploid anuran and urodelan species, as well as spontaneously originated and/or experimentally produced amphibian polyploids. The mechanisms by which polyploids can originate, the meiotic pairing configurations, the diploidization processes operating in polyploid genomes, the ...
