Ploidy dynamics and evolvability in fungi [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2016 Rapid responses to acute stresses are essential for stress survival and are critical to the ability of fungal pathogens to adapt to new environments or hosts. The rapid emergence of drug resistance is used as a model for how fungi adapt and survive stress conditions that inhibit the growth of progenitor cells. Aneuploidy and loss of heterozygosity (LOH)

Intraspecific C-value variation and the outcomes in Psidium cattleyanum Sabine essential oil
Brazilian Journal of Biology, 2022 Polyploidy, a numerical alteration of the karyotype, is one of the most important mechanisms in plant speciation and diversification, but could also be detected among populations, the cytotypes.

Analysis of DNA Polymerases Reveals Specific Genes Expansion in Leishmania and Trypanosoma spp.
Frontiers in Cellular and Infection Microbiology, 2020 Leishmaniasis and trypanosomiasis are largely neglected diseases prevailing in tropical and subtropical conditions. These are an arthropod-borne zoonosis that affects humans and some animals and is caused by infection with protozoan of the genera ...

Molecular Oncology, 2011 AbstractAneuploidy, often preceded by tetraploidy, is one of the hallmarks of solid tumors. Indeed, both aneuploidy and tetraploidy are oncogenic occurrences that are sufficient to drive neoplastic transformation and cancer progression. True to form, the tumor suppressor p53 obstructs propagation of these dangerous chromosomal events by either ...

Gender and ploidy in cancer survival [PDF]
Cellular Oncology, 2011 Females carry a better prognosis than men for many cancer types. We hypothesized that chromosomal changes, in particular numerical alterations of the sex chromosomes or the presence of near-triploidy may contribute to these gender differences.To characterize the influence of gender a literature search was performed for survival data of 27 tumor types ...

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

Chloroplast genome variation in upland and lowland switchgrass. [PDF]
PLoS ONE, 2011 Switchgrass (Panicum virgatum L.) exists at multiple ploidies and two phenotypically distinct ecotypes. To facilitate interploidal comparisons and to understand the extent of sequence variation within existing breeding pools, two complete switchgrass ...

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

Global analysis of the small RNA transcriptome in different ploidies and genomic combinations of a vertebrate complex--the Squalius alburnoides. [PDF]
PLoS ONE, 2012 The Squalius alburnoides complex (Steindachner) is one of the most intricate hybrid polyploid systems known in vertebrates. In this complex, the constant switch of the genome composition in consecutive generations, very frequently involving a change on ...

Direct Conversion of Fibroblasts to Megakaryocyte Progenitors
Cell Reports, 2016 Current sources of platelets for transfusion are insufficient and associated with risk of alloimmunization and blood-borne infection. These limitations could be addressed by the generation of autologous megakaryocytes (MKs) derived in vitro from somatic ...
