Higher ploidy coincides with inferior performance and no difference in drought tolerance in a mesocosm experiment with common reed (Phragmites australis)

Environmental and Experimental Botany
Climate change leads to more extreme weather events. Therefore, high stress tolerance is becoming increasingly critical for plants. A higher ploidy level has been reported to lead to higher stress tolerance in plants.

Cellular cannibalism: An insight

CHRISMED Journal of Health and Research, 2015
The phenomenon of cell cannibalism refers to the engulfment of cells within other cells. It is an unusual phenomenon associated with poor prognosis of high-grade cancers.

Maintenance and variation of chromosome ploidy under tissue culture conditions of different Camellia germplasms

Guangxi Zhiwu
The maintenance and variation of ploidy in plants are influenced by environmental factor, and the tissue culture regeneration can often cause changes of chromosome structures and ploidy levels.

Human megakaryocyte ploidy.

Histology and histopathology, 1999
We reviewed the literature concerning the history of determination of the ploidy of human megakaryocytes and its relationship with diseases. The ploidy of rabbit megakaryocytes was analyzed by microspectrophotometry in 1964, and the analysis of the ploidy in human megakaryocytes was first performed in 1968. Presently, microphotometry and flow cytometry

Virulence phenotypes result from interactions between pathogen ploidy and genetic background

Ecology and Evolution, 2020
Studying fungal virulence is often challenging and frequently depends on many contexts, including host immune status and pathogen genetic background. However, the role of ploidy has often been overlooked when studying virulence in eukaryotic pathogens ...

Tumor ploidy determination in low-pass whole genome sequencing and allelic copy number visualization using the Constellation Plot

Genome Biology
Ploidy determination across the genome has been challenging for low-pass-WGS tumor-only samples. We present BACDAC, a method that calculates tumor ploidy down to 1.2X effective tumor coverage.

Is Natural Population of Candida tropicalis Sexual, Parasexual, and/or Asexual?

Frontiers in Cellular and Infection Microbiology, 2021
Candida tropicalis is one of the most common opportunistic yeast pathogens of humans, especially prevalent in tropical and subtropical regions. This yeast has broad ecological distributions, can be found in both terrestrial and aquatic ecosystems ...

Intrapatient tumour heterogeneity and clonal evolution in an autopsy study of metastatic salivary gland cancer

Molecular Oncology, EarlyView.
Tumour heterogeneity and clonal evolution of metastatic salivary gland cancer were evaluated in two patients with adenoid carcinoma and one patient with myoepithelial carcinoma. Radiology‐guided autopsy enabled multi‐region sampling (total samples n = 149), followed by whole‐genome sequencing and phylogenetic reconstruction (17 tumour samples, 4–7 per ...

Inferring Variation in Copy Number Using High Throughput Sequencing Data in R

Frontiers in Genetics, 2018
Inference of copy number variation presents a technical challenge because variant callers typically require the copy number of a genome or genomic region to be known a priori.

ATZ‐1 promotes DNA replication efficiency to maintain normal meiotic function

FEBS Open Bio, EarlyView.
Absence of ATZ‐1 interferes with meiotic DNA replication and cell cycle function via CHK‐1. This causes downstream defects associated with DNA damage and genomic integrity. Taken together, this study suggests that ATZ‐1 influences DNA replication efficiency and cell cycle function to maintain normal meiotic function.
