Niche divergence and limits to expansion in the high polyploid Dianthus broteri complex [PDF]

open access: yes, 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 ...

Polyploidy breaks speciation barriers in Australian burrowing frogs Neobatrachus [PDF]

open access: yes, 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.

De novo construction of polyploid linkage maps using discrete graphical models [PDF]

open access: yes, 2018
Linkage maps are used to identify the location of genes responsible for traits and diseases. New sequencing techniques have created opportunities to substantially increase the density of genetic markers.

Induction of Synthetic Polyploids and Assessment of Genomic Stability in Lippia alba

open access: yesFrontiers in Plant Science, 2020
Polyploidy is widely recognized as a major evolutionary force in plants and has been reported in the genus Lippia (Verbenaceae). Lippia alba, the most studied species, has been documented as a polyploid complex involving at least four ploidal levels.

Polyploidization and domestication [PDF]

open access: yesSCIENTIA 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 ...

nPhase: an accurate and contiguous phasing method for polyploids

open access: yesGenome 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.
