Muller's ratchet and mutational meltdowns [PDF]
, 1993 We extend our earlier work on the role of deleterious mutations in the extinction of obligately asexual populations. First, we develop analytical models for mutation accumulation that obviate the need for time-consuming computer simulations in certain ...

Genes & Development, 1994 The Drosophila escargot (esg) gene encodes a C2-H2-type zinc finger protein that is expressed in the imaginal discs and histoblasts. In some esg mutants, the abdominal histoblasts become polyploid.

Current advances in haploid stem cells
Protein & Cell, 2019 Diploidy is the typical genomic mode in all mammals. Haploid stem cells are artificial cell lines experimentally derived in vitro in the form of different types of stem cells, which combine the characteristics of haploidy with a broad developmental ...

Effects of an Unusual Poison Identify a Lifespan Role for Topoisomerase 2 in Saccharomyces Cerevisiae [PDF]
, 2017 A progressive loss of genome maintenance has been implicated as both a cause and consequence of aging. Here we present evidence supporting the hypothesis that an age-associated decay in genome maintenance promotes aging in Saccharomyces cerevisiae (yeast)

Potential Drivers of Successful Biocontrol: A Perspective on Parasitoids
New Zealand Journal of Zoology, Volume 53, Issue 1, March 2026.Parasitoids are central to classical biological control, yet predicting their long‐term effectiveness post release remains challenging. In Aotearoa New Zealand, three Microctonus (Hymenoptera: Braconidae) species have been used against pest weevils, but key aspects of their biology remain poorly understood.

Molecular and immunohistochemical characteristics of complete hydatidiform moles
Balkan Journal of Medical Genetics, 2017 Molar pregnancy is a gestational trophoblastic disease that belongs to the category of precancerous lesions. On the other end of the spectrum are gestational trophoblastic neoplasms such as invasive mole, choriocarcinoma, placental site trophoblastic ...

Experimental Evolution Reveals Interplay between Sch9 and Polyploid Stability in Yeast. [PDF]
PLoS Genetics, 2016 Polyploidization has crucial impacts on the evolution of different eukaryotic lineages including fungi, plants and animals. Recent genome data suggest that, for many polyploidization events, all duplicated chromosomes are maintained and genome ...

Autopolyploidization‐Induced Chromatin Remodeling Regulates Leaf Size Variation in Brassica rapa
Advanced Science, Volume 13, Issue 9, 13 February 2026.This study demonstrates that monoploid, diploid, and autotetraploid Brassica rapa lines derived from the same genome exhibit distinct leaf morphology. Ploidy changes remodel chromatin accessibility and histone modifications to regulate gene expression, while key transcription factors BrGRF13 and BrARF11 control leaf size and polarity, driving ...

Induction of gynogenesis by heterogenous sperm and cold shock treatment in Epinephelus fuscoguttatus
Reproduction and Breeding, 2021 Gynogenesis is a chromosome set manipulation technique to accelerate inbred lines used for genomics analysis and genetic breeding. Groupers are hermaphroditic fish whereby they sexually mature as females and subsequently change sex to male. Production of

Isoenzyme electrophoresis of 30 isolates of Giardia from humans and felines [PDF]
, 1988 Thirty isolates of Giardia duodenalis from humans and felines were compared by isoenzyme electrophoresis. Using 10 enzyme systems, 13 different zymodemes were distinguished. The majority of zymodemes could be divided into two groups: one group comprising
