Magnification of Genes Coding for Ribosomal RNA in Saccharomyces cerevisiae [PDF]

open access: yes, 1977
When a strain of Saccharomyces cerevisiae monosomic for chromosome I and initially deficient for 25% of the genes coding for ribosomal RNA is repeatedly subcultured, the number of these genes increases to and remains stable at the number in the wild type.

Chromosome doubling of microspore-derived plants from cabbage (Brassica oleracea var. capitata L.) and broccoli (Brassica oleracea var. italica L.)

open access: yesFrontiers in Plant Science, 2015
Chromosome doubling of microspore-derived plants is an important factor in the practical application of microspore culture technology because breeding programs require a large number of genetically stable, homozygous doubled haploid plants with a high ...

Production of wheat-doubled haploids resistant to eyespot supported by marker-assisted selection

open access: yesElectronic Journal of Biotechnology, 2019
Background: Wheat is one of the most important crops cultivated all over the world. New high-yielding cultivars that are more resistant to fungal diseases have been permanently developed.

Inference of Population History using Coalescent HMMs: Review and Outlook

open access: yes, 2018
Studying how diverse human populations are related is of historical and anthropological interest, in addition to providing a realistic null model for testing for signatures of natural selection or disease associations.

A computational model of evolution: haploidy versus diploidy [PDF]

open access: yes, 1999
In this paper, the study of diploidy is introduced like and important mechanism for memory reinforcement in artificial environments where adaptation is very important.

Moldovan line MHI the source for obtaining a large number of haploid plants in maize [PDF]

open access: yesSelekcija i Semenarstvo, 2004
The hypothesis of the shortening the cycle of selection was tested in maize, by using the MHI line (Moldovan Haploid Inducer) for inducing haploids in five F1 elite single crosses, made for the purposes of further inbreeding and gaining new elite inbred ...

Inducer line generated double haploid seeds for combined waxy and opaque 2 grain quality in subtropical maize ( Zea mays. L.) [PDF]

open access: yes, 2018
The implementation of modern inducer lines in maize breeding can substantially decrease the time required to create elite inbred lines. In industrialized countries, this method has already largely replaced conventional backcross methods.

The effect of phytosulfokine alpha on haploid embryogenesis and gene expression of Brassica napus microspore cultures

open access: yesFrontiers in Plant Science
Microspore embryogenesis (ME) is the most powerful tool for creating homozygous lines in plant breeding and molecular biology research. It is still based mainly on the reprogramming of microspores by temperature, osmotic and/or nutrient stress.
