The polyploid continuum and the landscape of polyploid genomic variation. [PDF]
Am J BotAbstract Polyploid research has traditionally distinguished between autopolyploids and allopolyploids on the basis of evolutionary origins, modes of inheritance, or chromosomal pairing behavior during meiosis. It has long been recognized, however, that a binary classification does not accurately reflect the complexity and diversity ...

New Phytologist, 2021 SummaryPolyploidy is a dominant feature of extant plant diversity. However, major research questions, including whether polyploidy is important to long‐term evolution or is just ‘evolutionary noise’, remain unresolved due to difficulties associated with the generation and analysis of data from polyploid lineages.

Science China Life Sciences, 2012 Polyploids are organisms with three or more complete chromosome sets. Polyploidization is widespread in plants and animals, and is an important mechanism of speciation. Genome sequencing and related molecular systematics and bioinformatics studies on plants and animals in recent years support the view that species have been shaped by whole genome ...

Polyploidy breaks speciation barriers in Australian burrowing frogs Neobatrachus [PDF]
, 2020 Polyploidy has played an important role in evolution across the tree of life but it is still unclear how polyploid lineages may persist after their initial formation.

Priors for Genotyping Polyploids [PDF]
Bioinformatics, 2019 AbstractMotivationEmpirical Bayes techniques to genotype polyploid organisms usually either (i) assume technical artifacts are knowna priorior (ii) estimate technical artifacts simultaneously with the prior genotype distribution. Case (i) is unappealing as it places the onus on the researcher to estimate these artifacts, or to ensure that there are no ...

Quantification of ploidy in proteobacteria revealed the existence of monoploid, (mero-)oligoploid and polyploid species [PDF]
, 2011 Bacteria are generally assumed to be monoploid (haploid). This assumption is mainly based on generalization of the results obtained with the most intensely studied model bacterium, Escherichia coli (a gamma-proteobacterium), which is monoploid during ...

Polyploidy induction of black sesame (Sesamum indicum L.) for yield component improvement [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2021 This study was conducted with the aim of gaining the outcomes of polyploidy induction by soaking black sesame seeds, Sesamum indicum Linn, in 0.0%, 0.1%, 0.2%, 0.3% and 0.4% colchicine for 24 hours. When checking the characteristics of polyploidy using

Paleo-Polyploidization in Lycophytes
Genomics, Proteomics & Bioinformatics, 2020 Abstract Lycophytes and seed plants constitute the typical vascular plants. Lycophytes have been thought to have no paleo-polyploidization although the event is known to be critical for the fast expansion of seed plants. Here, genomic analyses including the homologous gene dot plot analysis detected multiple paleo-polyploidization events,

BMC Genomics, 2022 Background An important aspect of studying evolution is to understand how new species are formed and their uniqueness is maintained. Hybridization can lead to the formation of new species through reorganization of the adaptive system and significant ...

Loss of APC induces polyploidy as a result of a combination of defects in mitosis and apoptosis [PDF]
, 2007 Mutations in the adenomatous polyposis coli (APC) tumor suppressor gene initiate a majority of colorectal cancers. Acquisition of chromosomal instability is an early event in these tumors.
