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 ...

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 ...

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,

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 ...

Untangling nucleotide diversity and evolution of the H genome in polyploid Hordeum and Elymus species based on the single copy of nuclear gene DMC1. [PDF]
PLoS ONE, 2012 Numerous hybrid and polypoid species are found within the Triticeae. It has been suggested that the H subgenome of allopolyploid Elymus (wheatgrass) species originated from diploid Hordeum (barley) species, but the role of hybridization between polyploid

Niche divergence and limits to expansion in the high polyploid Dianthus broteri complex [PDF]
, 2019 Niche evolution in plant polyploids remains controversial and evidence for alternative patterns has been reported. Using the autopolyploid Dianthus broteri complex (2×, 4×, 6× and 12×) as a model, we aimed to integrate three scenarios – competitive ...

Polyploidization and domestication [PDF]
SCIENTIA SINICA Vitae, 2021 Crop domestication is the process to domesticate and propagate wild plants into cultivated crops, and its essence is to purposefully preserve the genetic variation information on the genome through artificial selection. Domestication has played an important role in the origin and evolution of human farming civilization, and promoted the sustainable ...
