AllCoPol: inferring allele co-ancestry in polyploids
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 ...

FISH-aimed karyotype analysis in Aconitum subgen : aconitum reveals excessive rDNA sites in tetraploid taxa [PDF]
, 2018 The location of 5S and 35S rDNA sequences in chromosomes of four Aconitum subsp. Aconitum species was analyzed after fluorescence in situ hybridization (FISH). Both in diploids (2n = 2x = 16; Aconitum variegatum, A. degenii) and tetraploids (2n = 4× = 32;

Problematic octaploid forms and a new chromosome number in the genus Achillea L., 2n = 126
Acta Societatis Botanicorum Poloniae, 2014 Among the offspring of a problematic form of Achillea sp., a 2n = 126 seedling which probably arose as the result of fusion of unreduced octo- and hexaploid gametes (72 + 54) was found along with seedlings having an octaploid chromosome number (2n = 72).

A Reappraisal of Polyploidy Events in Grasses (Poaceae) in a Rapidly Changing World
Biology, 2022 Around 80% of megaflora species became extinct at the Cretaceous–Paleogene (K–Pg) boundary. Subsequent polyploidy events drove the survival of thousands of plant species and played a significant historical role in the development of the most successful ...

Tetraploidization in citrus rootstocks: effect of genetic constitution and environment in chromosome duplication [PDF]
Crop Breeding and Applied Biotechnology, 2016 The objective of this study was to identify polyploid plants from citrus rootstocks and to evaluate the influence of the genetic constitution and of the environment on the frequency of chromosome duplication. Populations obtained from rootstock seeds of

Minimum error correction-based haplotype assembly: considerations for long read data
, 2020 The single nucleotide polymorphism (SNP) is the most widely studied type of genetic variation. A haplotype is defined as the sequence of alleles at SNP sites on each haploid chromosome.
