Uniparentality: advantages for range expansion in diploid and diploid-autopolyploid species

open access: yesBotanical Journal of the Linnean Society, 2022
AbstractUniparental reproduction, the capacity of an individual to produce offspring autonomously, is expected to facilitate range expansion of populations. Paspalum spp. reproduce uniparentally by sexual (self-fertility) and asexual (apomixis) reproduction and biparentally by sexual (self-sterility) reproduction.

Senescence in vitro and ionising radiations—the human diploid fibroblast model [PDF]

open access: yes, 1981
The influence of ionising radiations on ageing is still controversial. Since Hayflick established the concept that diploid cells have finite lifespan in vitro, human diploid fibroblast (HDF) cultures have been recognised as a potent experimental model ...

Ploidy-Dependent Response to Anticancer Drugs of Human Embryonic Stem Cells. [PDF]

open access: yesCell Prolif
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.

A reliable system for the transformation of cantaloupe charentais melon (Cucumis melo L. var. cantalupensis) leading to a majority of diploid regenerants [PDF]

open access: yes, 2000
An efficient system of transformation leading to a majority of transformed diploid plants from leaf explants of Cucumis melo L. var. Cantalupensis (cv. Védrantais) was developed.

The canonical equation of adaptive dynamics for Mendelian diploids and haplo-diploids [PDF]

open access: yesInterface Focus, 2013
One of the powerful tools of adaptive dynamics is its so-called canonical equation (CE), a differential equation describing how the prevailing trait vector changes over evolutionary time. The derivation of the CE is based on two simplifying assumptions, separation of population dynamical and mutational time scales and small mutational steps.
