Stem-Like Adaptive Aneuploidy and Cancer Quasispecies [PDF]

open access: yes, 2013
We analyze and reinterpret experimental evidence from the literature to argue for an ability of tumor cells to self-regulate their aneuploidy rate. We conjecture that this ability is mediated by a diversification factor that exploits molecular mechanisms

Metroplasty before IVF in women with a T‐shaped uterus: A clinical challenge

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract A T‐shaped uterus is a uterine malformation, which can be either congenital or acquired, potentially impairing fertility and increasing the risk of miscarriage. Diagnosis primarily relies on three‐dimensional ultrasound and hysteroscopy. Hysteroscopic metroplasty is the standard surgical intervention aimed at restoring normal uterine anatomy ...

Genome composition of 'Elatior'-begonias hybrids analyzed by genomic in situ hybridisation [PDF]

open access: yes, 2010
Interspecific hybridization of various tuberous Begonia species hybrids with Begonia socotrana results in so-called 'Elatior'-begonias hybrids (B. x hiemalis Fotsch).

Recombining your way out of trouble: the genetic architecture of hybrid fitness under environmental stress [PDF]

open access: yes, 2020
Hybridization between species is a fundamental evolutionary force that can both promote and delay adaptation. There is a deficit in our understanding of the genetic basis of hybrid fitness, especially in non-domesticated organisms.

Veronica paczoskiana is no more than a pine forest ecotype of V. spicata that evolved independently in forest‐steppes of Ukraine and the Altai region

open access: yesNordic Journal of Botany, EarlyView.
The Eurasian steppe area has been a dynamic vegetation biome during the Pleistocene with its repeated cycles of forest advances and retreats. Such a scenario allows the evolution of ecotypes at the ecotone with the potential for parallel evolution in different parts of the distribution area.

Genetic diversity of wheat (Triticum aestivum L.) plants-regenerants produced by anther culture

open access: yesВавиловский журнал генетики и селекции, 2016
The study of genetic diversity of wheat (Triticum aestivum L.) plants-regenerants produced by anther culture method from hybrids involved in the Latvian wheat breeding programme was performed. Flow cytometry was used to test ploidy of 3×103 cells of each

Pan-cancer Alterations of the MYC Oncogene and Its Proximal Network across the Cancer Genome Atlas [PDF]

open access: yes, 2018
Although theMYConcogene has been implicated incancer, a systematic assessment of alterations ofMYC, related transcription factors, and co-regulatoryproteins, forming the proximal MYC network (PMN),across human cancers is lacking.

Friends or foes? Polyploidy and competition in a grassland geophyte

open access: yesOikos, EarlyView.
Previous studies have suggested polyploids may possess a competitive advantage over diploids, due to their larger size, increased vigour or ability to better respond to abiotic stress. However, few studies have tested the effect of polyploidy on competitive ability directly, and only relatively recently has this oversight begun to be addressed. Here we
