Ploidy Regulation of Gene Expression
Science, 1999Microarray-based gene expression analysis identified genes showing ploidy-dependent expression in isogenic Saccharomyces cerevisiae strains that varied in ploidy from haploid to tetraploid. These genes were induced or repressed in proportion to the number of chromosome sets, regardless of the mating type.

Ploidy manipulation and performance
Aquaculture, 1986Abstract The chromosome set manipulation techniques of induced polyploidy, gynogenesis and androgenesis are likely to have significant applications in aquaculture. Induced triploidy is valuable for production of sterile individuals and increasing hybrid survival, and may be useful for producing individuals with increased heterozygosity.

Ploidy and Prognosis in Renal Carcinoma
British Journal of Urology, 1993SummaryThe value of tumour ploidy status as a prognostic indicator in renal carcinoma is disputed. In this retrospective study the DNA content of 90 primary and 10 secondary renal cell carcinomas was measured using flow cytometry. Data on recurrence and survival were available in all cases.

The puzzle of ploidy of Purkinje neurons
The Cerebellum, 2006This paper places attention on the discrepancies existing in the literature on the ploidy of Purkinje neurons and focuses on the special case of partial replication of their genome and on the unequal frequency of polyploid Purkinje neurons in the cerebellar cortex of the lobes and the vermis. Owing to the compartmental structure of the cerebellum, this

On the DNA content and ploidy of trypanosomes
Molecular and Biochemical Parasitology, 1982We have determined the nuclear and kinetoplast DNA content of two trypanosomatids by quantitative absorption and fluorescence cytophotometry of individual Feulgen-pararosaniline stained cells. For the insect trypanosomatid Crithidia fasciculata we find nuclear and kinetoplast DNA contents of 0.095 and 0.032 pg per non-replicating cell.

Ploidy Study in Sporothrix schenkii
Fungal Genetics and Biology, 1999Sporothrix schenckii is a dimorphic fungus that is pathogenic for humans. No sexual cycle has been reported for this fungus and little is known of its genetic constitution. To inquire into the ploidy state of Sporothrix schenckii, different approaches were followed: DNA content during transition from conidia to yeast, survival to ultraviolet ...

Ploidy Breeding in Ornamentals
2018Ploidy alterations are frequently used in ornamental plant breeding to induce novel variation, to overcome crossing barriers, or to create homogenous lines. Here we review three in vitro ploidy breeding tools with proven practical potential: mitotic polyploidization using mitosis arresting chemicals, meiotic polyploidization through the application of ...

Maize is unique among plant species in having techniques available in which conversion from diploidy to tetraploidy can be accomplished by the use of two meiotic mutants that produce diploid unreduced gametes—namely, asynaptic (as) (e.g., Miller 1963, Alexander 1957) and elongate (el) (Rhoades and Dempsey 1966). Although theoretically these two mutants
