The frequency and importance of polyploidy in tropical rainforest tree radiations. [PDF]
New PhytolSummary The presence of more than two copies of the genome in an organism, termed ‘polyploidy’, is a crucial force in plant evolution, generating genetic, phenotypic and ecological diversity. [Correction added on 22 January 2026, after first online publication: the preceding sentence has been corrected.] The Amazonian tree flora is the most species ...

Current 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 ...

Polyploidy and the proteome [PDF]
Biochimica et Biophysica Acta (BBA) - Proteins and Proteomics, 2016 Although major advances have been made during the past 20 years in our understanding of the genetic and genomic consequences of polyploidy, our knowledge of polyploidy and the proteome is in its infancy. One of our goals is to stimulate additional study, particularly broad-scale proteomic analyses of polyploids and their progenitors. Although it may be

Karyotyping and Distribution Patterns of Endemic Chinese Lilies: Insights Into Their Conservation Under Climate Change. [PDF]
Ecol EvolThis study integrates cytogenetic and ecological analyses of two endemic Chinese alpine lilies, Lilium lophophorum (2n = 24) and L. nanum (2n = 48), to establish a foundational understanding of their chromosomal diversity and distribution patterns. We document substantial intraspecific karyotypic variation in diploid L.

Polyploidy did not predate the evolution of nodulation in all legumes. [PDF]
PLoS 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
Biology, 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]
Comparative CytogeneticsPolyploidy 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 ...

Decidual cell polyploidization necessitates mitochondrial activity. [PDF]
PLoS 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
eLife, 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.
