Since 2014, France's blue mussel industry has been facing heavy mortality outbreaks (90-100%) affecting both juveniles and adults. This report presents evidence of heavy genomic abnormalities associated with mortality outbreaks in blue mussels, Mytilus edulis-galloprovincialis, from the Atlantic coast of France. In this study, ploidy characteristics of hemic cells were investigated using Flow C...

OBJECTIVES The common subtypes of renal tumors are conventional or clear cell carcinoma, papillary carcinoma, chromophobe carcinoma and oncocytoma. Each subtype has its distinct histogenesis and clinical evolution. DNA ploidy is viewed as a marker of gross genomic aberrations. The aim of this study is to evaluate the DNA ploidy in the common subtypes of renal tumors to increase our understandin...

ABSTRACT. The genus Magnolia includes over 250 species that range in ploidy level from diploid to hexaploid. Although there is basic information on ploidy levels of various species, sampling has been limited and little information on specific cultivars and hybrids is available. The objective of this research was to determine relative genome sizes and relationships to ploidy levels among a diver...

Aim To assess evidence for geographical and environmental range expansion through polyploidy in wild potatoes ( Solanum sect. Petota ). There are diploids, triploids, tetraploids, pentaploids and hexaploids in this group. Location Wild potatoes occur from the south-western USA (Utah and Colorado), throughout the tropical highlands of Mexico, Central America and the Andes, to Argentina, Chile an...

BACKGROUND AND METHODS 44 peripheral nerve sheath tumors (PNST) (27 schwannomas, 9 neurofibromas and 8 malignant peripheral nerve sheath tumors (MPNST)) were analyzed to determine DNA ploidy pattern and to clarify the conflicting data in the literature concerning this topic (whether benign PNSTs are aneuploid or not). For further insight we analyzed 6 schwannomas, one atypical neurofibroma and ...

A summary of the distribution of green toads containing most of the data published after the discovery of polyploid forms (1976) including a map, an index and a bibliography are presented and discussed. 21 Asian type localities of hitherto described nominal green toad taxa are shown. The tetraploids are distributed in high mountains and extremely continental regions with strong climatic shifts....

OBJECTIVE We investigated the correlation between ploidy or S-phase fraction (SPF) and the clinical pathological characteristics of patients with peritoneal carcinomatosis from ovarian cancer. We also assessed their relation with the in vivo and in vitro response to several chemotherapeutic agents. PATIENTS AND METHODS Fifty-three patients with peritoneal carcinomatosis from ovarian cancer we...

ploidy with a DNA index of 1.9 was detected in only 1 patient. This patient, who had a stage IA serous BOT, is alive without any recurrence after 96 months of observation following TAH/BSO. All the remaining 69 tumours showed diploid DNA content. The coefficient of variation for the diploid peaks ranged from 7.48 to 12.8 (mean 8.67) in diploid histograms despite using a low flow rate. A recent ...

Erianthus arundinaceus is not only an important germplasm resource for sugarcane breeding but also a potential bioenergy plant. Making clear the distribution of the chromosome ploidy of wild E. arundinaceus in china is the premise of the research and utilization of this species. Therefore, the objectives of this study were to determine the ploidy level and DNA content of the 55 E. arundinaceus ...

Polyploid plants often have higher biomass and superior crop qualities. Breeders therefore search for crop germplasm with higher ploidy levels; however, whether higher ploidy levels are associated with better performance remains unclear. Actinidia arguta and related species, whose commercialized fruit are referred to as kiwiberries, harbor a series of ploidy races in nature, offering an opportu...
