First Insight Into Multiple Paternity in the Potato Cyst Nematode <i>Globodera pallida</i> Facing Masculinizing Plant Resistance. [PDF]

open access: yesEcol Evol
This study demonstrated multiple paternity in the potato cyst nematode Globodera pallida: all females were polyandrous. Moreover, the female mating rate with different males appeared to remain stable, i.e., an average of seven fathering males, throughout the adaptation process to a masculinizing potato resistance.

Ploidy Variation and Spontaneous Haploid-Diploid Switching of Candida glabrata Clinical Isolates

open access: yesmSphere, 2022
The human fungal pathogen Candida glabrata is phylogenetically closely related to Saccharomyces cerevisiae, a model eukaryotic organism. Unlike S. cerevisiae, which has both haploid and diploid forms and a complete sexual cycle, C. glabrata has long been

The evolution of haploidy and diploidy [PDF]

open access: yesCurrent Biology, 2008
It is remarkable that one of the most fundamental features of an organism — its ploidy level — is so variable among taxa, with life cycles running the entire gamut from complete haploid dominance to complete diploid dominance. Theoretical studies have clarified many important genetic advantages to haploidy (for example, lower mutation load, more rapid ...

Hydatidiform mole diagnostics using circulating gestational trophoblasts isolated from maternal blood

open access: yesMolecular Genetics & Genomic Medicine, 2021
Background In gestational trophoblastic disease, the prognosis is related to the genetic constitution. In some cases, taking a biopsy is contraindicated. Methods In a pregnant woman, ultrasound scanning suggested hydatidiform mole.

Evolutionary route to diploidy and sex [PDF]

open access: yesProceedings of the National Academy of Sciences, 2001
By using a bit-string model of evolution, we find a successful route to diploidy and sex in simple organisms. Allowing the sexually reproducing diploid individuals to also perform mitosis, as they do in a haploid-diploid cycle, leads to the complete takeover of the population by sexual diploids.

EVALUATION OF SOME GROWTH CHARACTERS AND ALKALOID PRODUCTIVITY OF DIPLOIDY AND TETRAPLOIDY FORMS OF Datura stramonium AND Datura innoxia PLANTS [PDF]

open access: yesJournal of Soil Sciences and Agricultural Engineering, 2004
Field experiment was conducted to study the diversity in growth parameters and alkaloid production between diploidy and tetra ploidy levels of Datura stramonium and Datura innoxia plants. Increases in plant height.

Mutation accumulation may only be a minor force in shaping life-history traits, even when reproduction is sexual. [PDF]

open access: yesPLoS ONE, 2012
In a previous theoretical study we investigated whether adaptive or non-adaptive processes are more important in the evolution of senescence. We built a model that combined both processes and found that mutation accumulation is important only at those ...

Correlation between histological grading and ploidy status in oral leukoplakia, oral submucous fibrosis, and oral squamous cell carcinoma: A flow cytometric analysis

open access: yesJournal of Pharmacy and Bioallied Sciences, 2020
Background: Methods to analyze progression of carcinogenesis and stage of cancer are vital nowadays due to the high prevalence of these lesions. DNA ploidy analysis is one such important method in early diagnosis and improving prognosis.
