Case report: Germline CHEK2 mutation is associated with a giant cell glioblastoma

Frontiers in Oncology
Giant cell glioblastoma often exhibits genome instability and is frequently associated with mutations in genes involved in DNA repair pathways including TP53 and DNA mismatch repair genes.

Haploidy in Peach1

HortScience, 1974
Abstract Twenty-four haploids of peach [ Prunus persica (L.) Batsch] were obtained by visual selection in seedling populations growing in the greenhouse. Frequencies varied markedly between some progenies. Meiosis in pollen-mother cells was extremely irregular.

Economical qualities of crosses between doubled haploid sugar beet lines [PDF]

Agricultural Science and Technology, 2016
. The gynogenesis of isolated in vitro ovules is a basic method for the receipt of haploid plants and doubled haploid forms of sugar beet. The application of the induced haploidy is an excellent possibility for enrichment of the sugar beet gene fund and

Haploidy and androgenesis in Drosophila. [PDF]

Proceedings of the National Academy of Sciences, 1995
Adrogenesis, development from paternal but not maternal chromosomes, can be induced to occur in some organisms, including vertebrates, but has only been reported to occur naturally in interspecific hybrids of the Sicilian stick insect. Androgenesis has not been described previously in Drosophila.

Rapid sexual reproduction intensifies blooms of a mixotrophic dinoflagellate

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract Sexual reproduction is fundamental to the ecology and evolution of eukaryotes, yet its dynamics in microbial eukaryotes are often cryptic. Dinophysis are specialist mixotrophs that must balance prey capture, cell division, and sexual recombination during blooms, but relatively little is known about the occurrence and role of sex in their ...

Near-haploid common acute lymphoblastic leukaemia of childhood with a second hyperdiploid line: A DNA ploidy and fluorescence in-situ hybridization study

, 1998
Near-haploidy is a rare cytogenetic finding in childhood acute lymphoblastic leukaemia (ALL) and is associated with a poor prognosis. A second hyperdiploid line, occurring presumably by endoreduplication of the near-haploid stemline, is often observed ...

A Vertical Stacking Approach to Rapid Generation Cycling for Indoor Growth of Tall Annual Crops—The Case of Vicia faba L.

Plant Breeding, Volume 145, Issue 3, Page 637-648, June 2026.
ABSTRACT Accelerating breeding cycles through rapid generation turnover is a demonstrated strategy to improve the rate of genetic gain in a range of staple crops. This study presents a vertically stacked accelerated single‐seed descent (aSSD) protocol for faba bean (Vicia faba L.), aimed at rapid generation cycling while ensuring robust plant ...

Spider Mites: Genetic Models to Inform Herbivore and Chelicerate Biology

BioEssays, Volume 48, Issue 5, May 2026.
Chelicerates include spiders, scorpions and ticks, and also spider mites that damage crops. Many of the features that make spider mites crop pests have facilitated their adoption as genetically tractable chelicerates. The expanding genetic toolkit developed using spider mites has potential to inform genetic studies in other chelicerates as well ...

A century of theories of balancing selection

Biological Reviews, Volume 101, Issue 2, Page 804-825, April 2026.
ABSTRACT Traits that affect organismal fitness are often highly genetically variable. This genetic variation is vital for populations to adapt to their environments, but it is also surprising given that nature – after all – ‘selects’ the best genotypes at the expense of those that fall short.
