nPhase: an accurate and contiguous phasing method for polyploids
Genome Biology, 2020 While genome sequencing and assembly are now routine, we do not have a full, precise picture of polyploid genomes. No existing polyploid phasing method provides accurate and contiguous haplotype predictions.

AllCoPol: inferring allele co-ancestry in polyploids [PDF]
BMC Bioinformatics, 2020 Inferring phylogenetic relationships of polyploid species and their diploid ancestors (leading to reticulate phylogenies in the case of an allopolyploid origin) based on multi-locus sequence data is complicated by the unknown assignment of alleles found ...

Benchmarking small-variant genotyping in polyploids [PDF]
bioRxiv, 2021 Genotyping from sequencing is the basis of emerging strategies in the molecular breeding of polyploid plants. However, compared with the situation for diploids, where genotyping accuracies are confidently determined with comprehensive benchmarks ...

Genes, 2020 Floral organ size, especially the size of the corolla, plays an important role in plant reproduction by facilitating pollination efficiency. Previous studies have outlined a hypothesized organ size pathway. However, the expression and function of many of

Natural and artificial polyploids in aquaculture
, 2017 Genome polyploidy has been revealed to result in evolutionary advantages and novelties, and therefore, polyploid aquatic animals may possess excellent traits of economic interest including rapid growth, extensive adaptability and disease resistance.

PolyHaplotyper: haplotyping in polyploids based on bi-allelic marker dosage data
BMC Bioinformatics, 2022 Background For genetic analyses, multi-allelic markers have an advantage over bi-allelic markers like SNPs (single nucleotide polymorphisms) in that they carry more information about the genetic constitution of individuals. This is especially the case in

The Case of the Missing Ancient Fungal Polyploids
American Naturalist, 2016 Polyploidy—the increase in the number of whole chromosome sets—is an important evolutionary force in eukaryotes. Polyploidy is well recognized throughout the evolutionary history of plants and animals, where several ancient events have been hypothesized ...

Progenitor-derivative relationships of Hordeum polyploids (Poaceae, Triticeae) inferred from sequences of TOPO6, a nuclear low-copy gene region. [PDF]
PLoS ONE, 2012 Polyploidization is a major mechanism of speciation in plants. Within the barley genus Hordeum, approximately half of the taxa are polyploids. While for diploid species a good hypothesis of phylogenetic relationships exists, there is little information ...

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 ...
