Triticale haploidy in vitro (literature review)

open access: yesЗерновое хозяйство России, 2022
Triticale (× Triticosecale Wittmack) is a hybridized grain crop developed from wheat and rye crossings. Today, triticale is a multipurpose commercial grain crop with great potential as a human food and animal feed.

Current advances in haploid stem cells

open access: yesProtein & Cell, 2019
Diploidy is the typical genomic mode in all mammals. Haploid stem cells are artificial cell lines experimentally derived in vitro in the form of different types of stem cells, which combine the characteristics of haploidy with a broad developmental ...

Mitotic recombination accelerates adaptation in the fungus Aspergillus nidulans. [PDF]

open access: yesPLoS Genetics, 2007
Understanding the prevalence of sexual reproduction in eukaryotes is a hard problem. At least two aspects still defy a fully satisfactory explanation, the functional significance of genetic recombination and the great variation among taxa in the relative

The Plot Thickens: Haploid and Triploid-Like Thalli, Hybridization, and Biased Mating Type Ratios in Letharia

open access: yesFrontiers in Fungal Biology, 2021
The study of the reproductive biology of lichen fungal symbionts has been traditionally challenging due to their complex lifestyles. Against the common belief of haploidy, a recent genomic study found a triploid-like signal in Letharia.

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

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'
