Prenatal Genetic Testing for Beckwith-Wiedemann Syndrome: Considerations, Challenges and Observations (A Real-World Study). [PDF]

Prenat Diagn
ABSTRACT Objective Prenatal genetic testing for imprinting disorders is rarely requested with the exception of Beckwith‐Wiedemann syndrome (BWS) which is associated with specific ultrasound findings (e.g., placental mesenchymal dysplasia, omphalocele). However, genetic testing for BWS is challenging as aberrant DNA methylation has to be addressed which

Polyploidy in tissues of plants in vitro of grape somaclones

BIO Web of Conferences, 2021
In vitro experimental plants obtained by clonal micropropagation of 9 grape somaclones of 5 original forms were the material for cytogenetic research. A biological microscope XSP-146TP was used for cytogenetic analysis.

Genomics is modifying our concepts of evolution in homosporous and heterosporous vascular plants. [PDF]

Am J Bot
Abstract Across the tree of life, and particularly within land plants, there is a wide diversity and disparity of genome structure. The most well‐studied are angiosperms, comprising mostly small and dynamic genomes, with a history of ancient whole genome duplications.

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

Genome Changes After Gene Duplication: Haploidy vs. Diploidy

, 2010
Since genome size and the number of duplicate genes observed in genomes increase from haploid to diploid organisms, diploidy might provide more evolutionary probabilities through gene duplication.

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.
