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.

Polyploidy induction of black sesame (Sesamum indicum L.) for yield component improvement [PDF]

open access: yesSongklanakarin 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

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 ...

Phylogeographic relationships and the evolutionary history of the Carassius auratus complex with a newly born homodiploid raw fish (2nNCRC)

open access: yesBMC 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 ...

A genotyping protocol for multiple tissue types from the polyploid tree species Sequoia sempervirens (Cupressaceae). [PDF]

open access: yes, 2015
Premise of the studyIdentifying clonal lineages in asexually reproducing plants using microsatellite markers is complicated by the possibility of nonidentical genotypes from the same clonal lineage due to somatic mutations, null alleles, and scoring ...

Clinicopathological analysis of polyploid diffuse large B-cell lymphoma. [PDF]

open access: yesPLoS ONE, 2018
Polyploid chromosomes are those with more than two sets of homologous chromosomes. Polyploid chromosomal abnormalities are observed in various malignant tumors. The prognosis in such cases is generally poor.

Meiotic behavior of two polyploid species of genus Pleurodema (Anura: Leiuperidae) from central Argentina [PDF]

open access: yes, 2014
Polyploidy is an important evolutionary force but rare in vertebrates. However, in anurans, the genus Pleurodema has polyploid species, two of them tetraploid and one octoploid.

Formation of autotriploid Carassius auratus and its fertility-related genes analysis

open access: yesBMC Genomics, 2021
Background Formation of triploid organism is useful in genetics and breeding. In this study, autotriploid Carassius auratus (3nRR, 3n = 150) was generated from Carassius auratus red var. (RCC, 2n = 100) (♀) and autotetraploid Carassius auratus (4nRR, 4n =
