Distant hybridization as a method of haploid production in cereals

open access: yesБиотехнология и селекция растений, 2019
Elimination of chromosomes is a phenomenon widespread in distant hybrids. It ranges from the loss of one or two chromosomes to elimination of whole chromosome complement of one of the parents.

Rapid generation of murine haploid-induced trophoblast stem cells via a Tet-on system

open access: yesSTAR Protocols, 2021
Summary: Haploid trophoblast stem cells (TSCs) are advanced in studying placental development for their placental precursor and homozygous features. Here, we describe how to generate haploid-induced TSCs (haiTSCs) from haploid embryonic stem cells with a

The evolution of hermaphroditism by an infectious male-derived cell lineage : an inclusive-fitness analysis [PDF]

open access: yes, 2014
This work was supported by funding from Balliol College, the Royal Society (A.G.), and the University of Groningen (L.R.).There has been much recent interest in the role for genetic conflicts to drive the evolution of genetic systems.

How to make a haploid male

open access: yesEvolution Letters, 2019
Haplodiploidy has evolved repeatedly among invertebrates, and appears to be associated with inbreeding. Evolutionary biologists have long debated the possible benefits for females in diplodiploid species to produce haploid sons–beginning their population'

Comparative pollination efficiency of freshly harvested pollen of Imperata cylindrica and Zea mays for haploid induction in bread wheat [PDF]

open access: yes, 2016
Pollen viability is among the critical factors, which determine the success of a doubled haploidy breeding programme, thus the present investigation was undertaken to assess the functional viability and relative longevity of the pollen from Zea mays and ...

Generation of Mouse Haploid Somatic Cells by Small Molecules for Genome-wide Genetic Screening

open access: yesCell Reports, 2017
The recent success of derivation of mammalian haploid embryonic stem cells (haESCs) has provided a powerful tool for large-scale functional analysis of the mammalian genome.

Polycomb-mediated repression of paternal chromosomes maintains haploid dosage in diploid embryos of Marchantia

open access: yeseLife, 2022
Complex mechanisms regulate gene dosage throughout eukaryotic life cycles. Mechanisms controlling gene dosage have been extensively studied in animals, however it is unknown how generalizable these mechanisms are to diverse eukaryotes.
