Polyploidy-associated autophagy promotes larval tracheal histolysis at Drosophila metamorphosis [Dataset]

open access: yes, 2023
Polyploidy is an extended phenomenon in biology. However, its physiological significance and whether it defines specific cell behaviors is not well understood.

Decidual cell polyploidization necessitates mitochondrial activity. [PDF]

open access: yesPLoS ONE, 2011
Cellular polyploidy has been widely reported in nature, yet its developmental mechanism and function remain poorly understood. In the present study, to better define the aspects of decidual cell polyploidy, we isolated pure polyploid and non-polyploid ...

Polyploidy in the adult Drosophila brain

open access: yeseLife, 2020
Long-lived cells such as terminally differentiated postmitotic neurons and glia must cope with the accumulation of damage over the course of an animal’s lifespan. How long-lived cells deal with ageing-related damage is poorly understood.

Regulated polyploidy in halophilic archaea [PDF]

open access: yes, 2006
Polyploidy is common in higher eukaryotes, especially in plants, but it is generally assumed that most prokaryotes contain a single copy of a circular chromosome and are therefore monoploid.

Polyploidy : a biological force from cells to ecosystems [PDF]

open access: yes, 2020
Polyploidy, resulting from the duplication of the entire genome of an organism or cell, greatly affects genes and genomes, cells and tissues, organisms, and even entire ecosystems.

Evolution by duplication: paleopolyploidy events in plants reconstructed by deciphering the evolutionary history of VOZ transcription factors

open access: yesBMC Plant Biology, 2018
Background Facilitated by the rapid progress of sequencing technology, comparative genomic studies in plants have unveiled recurrent whole genome duplication (i.e. polyploidization) events throughout plant evolution.

Induced polyploidy deeply influences reproductive life cycles, related phytochemical features, and phytohormonal activities in blackberry species

open access: yesFrontiers in Plant Science, 2022
In some cases, polyploidy is an important phenomenon in the evolution of fruit crops. Polyploidy can be used in fruit breeding programs to develop varieties with higher yields and better fruit quality, as well as better adaptation to adverse ...

Extreme Polyploidy Reveals Functional Trade-Offs in Plant Drought Responses. [PDF]

open access: yesPlant Cell Environ
ABSTRACT Polyploidy shapes plant physiology and anatomy, yet the extent to which different ploidy levels influence drought responses remains unclear. Here, we investigated how ploidy affects cell‐level coordination and functional traits associated with water transport and retention.

Cytotaxonomical aspects of Antarctic mosses, with special reference to the proportion of polyploidy

open access: yesAntarctic Record, 1994
The evolutionary tendency concerning karyological features, especially the proportion of polyploidy and infraspecific polyploidy in Antarctic mosses is reviewed.

Whole-Genome Doubling as a source of cancer: how, when, where, and why?

open access: yesFrontiers in Cell and Developmental Biology, 2023
Chromosome instability is a well-known hallmark of cancer, leading to increased genetic plasticity of tumoral cells, which favors cancer aggressiveness, and poor prognosis.
