Effects of ploidy level and haplotype on variation of photosynthetic traits: Novel evidence from two Fragaria species.

PLoS ONE, 2017
To reveal the effects of ploidy level and haplotype on photosynthetic traits, we chose 175 genotypes of wild strawberries belonging to two haplotypes at two types of ploidy levels (diploidy and tetraploidy) and measured photosynthetic traits. Our results

Mutagenesis by retroviral insertion in chemical mutagen-generated quasi-haploid mammalian cells

BioTechniques, 2007
Diploidy is a major obstacle to the mutagenic analysis of function in cultured mammalian cells. Here, we show that 6–8 rounds of chemical mutagenesis generates quasi-haploid cells that can be used as targets for insertional mutagenesis using a specially ...

Applications of Genome Editing Technology in Research on Chromosome Aneuploidy Disorders

Cells, 2020
Chromosomal segregation errors in germ cells and early embryonic development underlie aneuploidies, which are numerical chromosomal abnormalities causing fetal absorption, developmental anomalies, and carcinogenesis.

Adaptation to high ethanol reveals complex evolutionary pathways [PDF]

, 2015
Tolerance to high levels of ethanol is an ecologically and industrially relevant phenotype of microbes, but the molecular mechanisms underlying this complex trait remain largely unknown.

A single mutation results in diploid gamete formation and parthenogenesis in a Drosophila yemanuclein-alpha meiosis I defective mutant

BMC Genetics, 2010
Background Sexual reproduction relies on two key events: formation of cells with a haploid genome (the gametes) and restoration of diploidy after fertilization.

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

PLoS 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

Purkinje Cardiomyocytes of the Adult Ventricular Conduction System Are Highly Diploid but Not Uniquely Regenerative

Journal of Cardiovascular Development and Disease, 2023
Adult hearts are characterized by inefficient regeneration after injury, thus, the features that support or prevent cardiomyocyte (CM) proliferation are important to clarify.
