Ploidy in cyanobacteria [PDF]

open access: yesFEMS Microbiology Letters, 2011
A recently developed real-time PCR method for the determination of genome copy numbers was optimized for the application to cyanobacteria. Three species were chosen to represent a fresh water species, a salt water species, and two strains of a widely used laboratory species.

Extreme Polyploidy of Carsonella, an Organelle-Like Bacterium with a Drastically Reduced Genome

open access: yesMicrobiology Spectrum, 2022
Polyploidy is the state of having multiple copies of the genome within a nucleus or a cell, which has repeatedly evolved across the domains of life. Whereas most bacteria are monoploid, some bacterial species and endosymbiotic organelles that are derived

How germline genes promote malignancy in cancer cells

open access: yesBioEssays, Volume 45, Issue 1, January 2023., 2023
We hypothesize that activation of a “germline program” promotes oncogenesis. Expression of otherwise germline specific genes may result in pseudomeiotic activity, thereby promoting oncogenesis through genomic instability. Other processes that are differentially regulated in the germline, such as migration and epigenetic – and metabolic plasticity, may ...

Discovery and Characterization of Novel Fertile Triploids and a New Chromosome Number in Caladium (Caladium × hortulanum)

open access: yesHortScience, 2022
Cultivated caladium (Caladium × hortulanum; 2n = 2x = 30) is an important ornamental aroid for the environmental horticulture industry. A better understanding of its genetic diversity is needed for continued improvement of caladium.

Genomic characterization reveals distinct mutation landscapes and therapeutic implications in neuroendocrine carcinomas of the gastrointestinal tract

open access: yesCancer Communications, Volume 42, Issue 12, Page 1367-1386, December 2022., 2022
Abstract Background Neuroendocrine carcinomas of the gastrointestinal tract (GI‐NECs) remain a disease of grim prognosis with limited therapeutic options. Their molecular characteristics are still undefined. This study aimed to explore the underlying genetic basis and heterogeneity of GI‐NECs.

In vitro Ploidy Manipulation for Crop Improvement

open access: yesFrontiers in Plant Science, 2020
In vitro regeneration systems provide a powerful tool for manipulating ploidy to facilitate breeding and development of new crops. Polyploid induction can expand breeding opportunities, assist with the development of seedless triploid cultivars, enhance ...

Radiosensitization of calreticulin‐overexpressing human glioma cell line by the polyphenolic acetate 7, 8‐diacetoxy‐4‐methylcoumarin

open access: yesCancer Reports, Volume 5, Issue 12, December 2022., 2022
Abstract Background Calreticulin (CRT), an endoplasmic reticulum–resident protein generally overexpressed in cancer cells, is associated with radiation resistance. CRT shows higher transacetylase activity, as shown by us earlier, in the presence of the polyphenolic acetates (like 7, 8‐diacetoxy‐4‐methylcoumarin, DAMC) and modifies the activity of a ...

Are tri‐pronuclear embryos that show two normal‐sized pronuclei and additional smaller pronuclei useful for embryo transfer?

open access: yesReproductive Medicine and Biology, 2022
Purpose This study aimed to analyze whether tripronuclear (3PN) zygotes, with two normal‐sized PNs and an additional smaller PN (2.1PN), can be used for embryo transfer.

Chromosome Painting Provides Insights Into the Genome Structure and Evolution of Sugarcane

open access: yesFrontiers in Plant Science, 2021
The genus Saccharum is composed of species with high polyploidy and highly varied chromosome numbers, laying a challenge for uncovering its genomic structure and evolution.
