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 ...

New 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

Cytogenetic 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 ...

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

Chromosomal aberrations in transitional cell carcinoma that are predictive of disease outcome are independent of polyploidy [PDF]
, 1999 Objective To determine whether aneusomy for chromosomes 7, 9 and 17 (reported to predict recurrence in up to 65% of patients with superficial transitional cell bladder cancer and thus providing the opportunity for early and effective treatment) reflects ...

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 ...

Traversing the effects of ploidy changes in different Eragrostis curvula genotypes through high-throughput RNA sequencing. [PDF]
Plant GenomeAbstract Polyploidization has played a key role in plant genome evolution. Eragrostis curvula (Schrad.) Ness, a perennial forage grass species of the Poaceae family, is an excellent model for investigating genome duplication due to its natural variation in ploidy levels.
