Polyploidy breaks speciation barriers in Australian burrowing frogs Neobatrachus [PDF]

, 2020
Polyploidy has played an important role in evolution across the tree of life but it is still unclear how polyploid lineages may persist after their initial formation.

Generation of miniploid cells and improved natural transformation procedure for a model cyanobacterium Synechococcus elongatus PCC 7942

Frontiers in Microbiology, 2022
The biotechnologically important and naturally transformable cyanobacterium, Synechococcus elongatus PCC 7942, possesses multiple genome copies irrespective of its growth rate or condition.

Quantification of ploidy in proteobacteria revealed the existence of monoploid, (mero-)oligoploid and polyploid species [PDF]

, 2011
Bacteria are generally assumed to be monoploid (haploid). This assumption is mainly based on generalization of the results obtained with the most intensely studied model bacterium, Escherichia coli (a gamma-proteobacterium), which is monoploid during ...

Parent-of-Origin Effects on Seed Size Modify Heterosis Responses in Arabidopsis thaliana

Frontiers in Plant Science, 2022
Parent-of-origin effects arise when a phenotype depends on whether it is inherited maternally or paternally. Parent-of-origin effects can exert a strong influence on F1 seed size in flowering plants, an important agronomic and life-history trait that can

How to halve ploidy : lessons from budding yeast meiosis [PDF]

, 2012
Maintenance of ploidy in sexually reproducing organisms requires a specialized form of cell division called meiosis that generates genetically diverse haploid gametes from diploid germ cells.

DNA content analysis of colorectal cancer defines a distinct ‘microsatellite and chromosome stable’ group but does not predict response to radiotherapy [PDF]

, 2014
Colorectal cancers (CRC) are thought to have genetic instability in the form of either microsatellite instability (MSI) or chromosomal instability (CIN).

Efficient and crucial quality control of HAP1 cell ploidy status

Biology Open, 2020
The near-haploid human cell line HAP1 recently became a popular subject for CRISPR/Cas9 editing, since only one allele requires modification. Through the gene-editing service at Horizon Discovery, there are at present more than 7500 edited cell lines ...

Effects of Donor x Inducer Interaction on the Success of Haploid Induction and Comparison of Haploid Seed Identification Methods in the In vivo Maternal Haploid Technique in Maize

Journal of Agricultural Sciences, 2022
This study was conducted to investigate the effect of donor and inducer lines on the haploid induction rate in the in vivo maternal doubled haploid technique in maize and to compare the methods used in haploid seed separation.

Ploidy and the evolution of parasitism [PDF]

Proceedings of the Royal Society B: Biological Sciences, 2011
Levels of parasitism are continuously distributed in nature. Models of host–parasite coevolution, however, typically assume that species can be easily characterized as either parasitic or non-parasitic. Consequently, it is poorly understood which factors influence the evolution of parasitism itself.

Intricate Distribution Patterns of Six Cytotypes of Allium oleraceum at a Continental Scale: Niche Expansion and Innovation Followed by Niche Contraction With Increasing Ploidy Level

Frontiers in Plant Science, 2020
The establishment and success of polyploids are thought to often be facilitated by ecological niche differentiation from diploids. Unfortunately, most studies compared diploids and polyploids, ignoring variation in ploidy level in polyploids.
