Multi-Omics Unveils the Dual-Life of the Aquatic Plant Potamogeton nodosus. [PDF]

open access: yesPhysiol Plant
ABSTRACT Heterophylly, characterized by distinct leaf morphologies, is an adaptive strategy evolved by some aquatic plants to cope with the contrasting environments in which they grow. It is shaped by environmental factors and by hormones, particularly abscisic and gibberellic acids.

The consequences of tetraploidy and aneuploidy [PDF]

open access: yesJournal of Cell Science, 2008
Polyploidy, an increased number of chromosome sets, is a surprisingly common phenomenon in nature, particularly in plants and fungi. In humans, polyploidy often occurs in specific tissues as part of terminal differentiation. Changes in ploidy can also result from pathophysiological events that are caused by viral-induced cell fusion or erroneous cell ...

Discovery of tetraploidy in a mammal [PDF]

open access: yesNature, 1999
The red viscacha rat is unaffected by having double the usual number of chromosomes. Polyploidy, or having more than a pair of each type of chromosome, is considered to be unlikely in mammals because it would disrupt the mechanism of dosage compensation that normally inactivates one X chromosome in females1.

Clinicopathological analysis of near-tetraploidy/tetraploidy acute myeloid leukaemia [PDF]

open access: yesJournal of Clinical Pathology, 2015
Aims Near-tetraploidy/tetraploidy (NT/T) is a rare cytogenetic alteration in acute myeloid leukaemia (AML). NT/T-AML is categorised as complex cytogenetics and therefore, presumed to have an unfavourable prognosis.

Induction of Polyploidy in Citrus Rootstocks through In Vitro Colchicine Treatment of Seed-Derived Explants

open access: yesAgronomy, 2023
Polyploidy, frequently observed in citrus species, aids in achieving better adaptation to environmental stresses. In this context, the current work aims to develop stable tetraploids in citrus rootstock cultivars, viz., Rough lemon, Rangpur lime and ...

Tetraploidy causes chromosomal instability in acentriolar mouse embryos

open access: yesNature Communications, 2019
During cell division, tetraploidy can drive chromosomal instability (CIN) via supernumerary centrosomes, but it is unclear if this is the only route to CIN. Here the authors show that, in early mouse embryos, tetraploidy can drive chromosomal instability

The fate of extra centrosomes in newly formed tetraploid cells: should I stay, or should I go?

open access: yesFrontiers in Cell and Developmental Biology, 2023
An increase in centrosome number is commonly observed in cancer cells, but the role centrosome amplification plays along with how and when it occurs during cancer development is unclear. One mechanism for generating cancer cells with extra centrosomes is

Tetraploidy and tumor development

open access: yesOncotarget, 2014
Tetraploid cells, which contain a doubled chromosomal content, are known to facilitate tumorigenesis [1]. Two specific characteristics of tetraploid cells play major roles in promoting neoplastic transformation. First, proliferating tetraploid cells are genomically unstable and accumulate both numerical and structural chromosomal abnormalities.

An Emerging Animal Model for Querying the Role of Whole Genome Duplication in Development, Evolution, and Disease

open access: yesJournal of Developmental Biology, 2023
Whole genome duplication (WGD) or polyploidization can occur at the cellular, tissue, and organismal levels. At the cellular level, tetraploidization has been proposed as a driver of aneuploidy and genome instability and correlates strongly with cancer ...
