Matromorfie in Brassica oleracea L. [PDF]
INLEIDINGDe ontwikkeling van een diploid embryo uit een onbevruchte eicel van een diploide plant, mede ten gevolge van de stimulerende invloed van soort- of geslachtsvreemd pollen, wordt matromorfie of pseudogame diploide parthenogenese genoemd (EENINK ...

Hybridization may lead to introgression of genes among species. Introgression may be bidirectional or unidirectional, depending on factors such as the demography of the hybridizing species, or the nature of reproductive barriers between them.

Ploidy‐Dependent Response to Anticancer Drugs of Human Embryonic Stem Cells
Using isogenic hESCs, differing only in their ploidy level, we show the effect of ploidy on the resistance to anticancer drugs. We demonstrate that polyploidy, by itself, confers sensitivity to chemotherapies, leading to higher apoptosis and delayed proliferation, while the loss of p53 reverses the phenotype, demonstrating higher resistance.

Evolutionary Metabolomics Reveals Domestication-Associated Changes in Tetraploid Wheat Kernels
Domestication and breeding have influenced the genetic structure of plant populations due to selection for adaptation from natural habitats to agro-ecosystems. Here, we investigate the effects of selection on the contents of 51 primary kernel metabolites

Ploidy‐dependent modulation of DNA replication kinetics in Xenopus
Using an interspecies replication system with Xenopus frog species of different ploidy levels, we investigated how DNA replication adapts to polyploidization. While replication was slower in tetraploid than in diploid nuclei, dodecaploid nuclei unexpectedly replicated faster than tetraploid nuclei. Our findings show that increasing genome size does not

The response to tissue culture of a series of related, agronomically useful, dihaploid (2n=2x=24) and tetraploid (2n=4x=48) S. tuberosum genotypes was assessed by regenerating shoots from leaf explants.

Diploid and Tetraploid Aranda Wendy Scott from Meristem Culture [PDF]
Diploid and tetraploid plants arising from mericloning diploid Aranda Wendy Scott 'Greenfield' was investigated. Out of 77 meri-cloned plants 28 (36.4%) were tetraploid.

Inhibition of Chk1 kills tetraploid tumor cells through a p53-dependent pathway.
Tetraploidy constitutes an adaptation to stress and an intermediate step between euploidy and aneuploidy in oncogenesis. Tetraploid cells are particularly resistant against genotoxic stress including radiotherapy and chemotherapy.

A new variety of Solanum sisymbriifolium obtained by in vitro polyploidization [PDF]
Solanum sisymbriifolium is a shrub native to South America and considered a weed of several important crops. Despite this, this species has proven nematicidal capacity and medicinal properties, due to its ability to produce alkaloids. Thus, the objective

A high‐quality reference genome for the elite peanut cultivar Zhonghua No. 5 revealed differing evolutionary paths between the two peanut subgenomes. SubA has higher overall gene expression and more open chromatin, whereas SubB has stronger structural organization, higher DNA methylation, and greater adaptive diversity associated with peanut evolution ...
