Ploidy determination of Canadida albicans [PDF]
Journal of Bacteriology, 1979 The dimorphic yeast Candida albicans, as a member of the fungi imperfecti, has been assumed to be in the haploid, or imperfect, state. The deoxyribonucleic acid content of this species has been measured by flow microfluorometry, a technique capable of analyzing single cells.

FEMS Microbiology Letters, 2011 A recently developed real-time PCR method for the determination of genome copy numbers was optimized for the application to cyanobacteria. Three species were chosen to represent a fresh water species, a salt water species, and two strains of a widely used laboratory species.

Ploidy and the evolution of parasitism [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2011 Levels of parasitism are continuously distributed in nature. Models of host–parasite coevolution, however, typically assume that species can be easily characterized as either parasitic or non-parasitic. Consequently, it is poorly understood which factors influence the evolution of parasitism itself.

The hybrid number of a ploidy profile
Journal of Mathematical Biology, 2022 AbstractPolyploidization, whereby an organism inherits multiple copies of the genome of their parents, is an important evolutionary event that has been observed in plants and animals. One way to study such events is in terms of the ploidy number of the species that make up a dataset of interest.

Ploidy levels and reproductive behaviour in invasive Hieracium pilosella in Patagonia [PDF]
, 2011 Within a population of invasive Hieracium pilosella in Chilean Patagonia we found two ploidy levels, pentaploid and hexaploid. Each ploidy level was represented by one clone.

Interspecific hybridization of sturgeon species affects differently their gonadal development
Czech Journal of Animal Science, 2018 Gonad development in fish is generally assumed to be negatively influenced by interspecific hybridization, resulting in sterility or sub-sterility. However, this is not the case in sturgeons (Acipenseridae), in which fertile hybrids are common.

CENH3-GFP: a visual marker for gametophytic and somatic ploidy determination in Arabidopsis thaliana [PDF]
, 2016 Background: The in vivo determination of the cell-specific chromosome number provides a valuable tool in several aspects of plant research. However, current techniques to determine the endosystemic ploidy level do not allow non-destructive, cell-specific

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

Ploidy dynamics and evolvability in fungi [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2016 Rapid responses to acute stresses are essential for stress survival and are critical to the ability of fungal pathogens to adapt to new environments or hosts. The rapid emergence of drug resistance is used as a model for how fungi adapt and survive stress conditions that inhibit the growth of progenitor cells. Aneuploidy and loss of heterozygosity (LOH)
