Variance of ploidy in Candida albicans [PDF]
Journal of Bacteriology, 1982 Determination of ploidy was performed on isolates of Candida albicans from clinical sources by measuring nuclear DNA content with fluorescent microscope photometry. By this criterion and UV irradiation survival experiments, haploid, diploid, and tetraploid strains were identified in this organism.

An Improved Natural Transformation Protocol for the Cyanobacterium Synechocystis sp. PCC 6803
Frontiers in Plant Science, 2020 The naturally transformable cyanobacterium Synechocystis sp. PCC 6803 is a widely used chassis strain for the photosynthetic production of chemicals. However, Synechocystis possesses multiple genome copies per cell which means that segregating mutations ...

Epigenetic regulation of repetitive DNA through mitotic asynchrony following double fertilization in angiosperms [PDF]
arXiv, 2013 Several recent studies show that companion cells in flowering plant gametophytes relax epigenetic control of transposable elements (TEs) to promote production of small RNA that presumably assist nearby reproductive cells in management of TEs. In light of this possibility, a closer look at the timing of cell division in relation to angiosperm double ...

The coordination of ploidy and cell size differs between cell layers in leaves
Development, 2016 Growth and developmental processes are occasionally accompanied by multiple rounds of DNA replication, known as endoreduplication. Coordination between endoreduplication and cell size regulation often plays a crucial role in proper organogenesis and cell

Ploidy and the Predictability of Evolution in Fishers Geometric Model [PDF]
arXiv, 2013 Predicting adaptive evolutionary trajectories is a primary goal of evolutionary biology. One can differentiate between forward and backward predictability, where forward predictability measures the likelihood of the same adaptive trajectory occurring in independent evolutions and backward predictability measures the likelihood of a particular adaptive ...

Hepatocyte Ploidy Is a Diversity Factor for Liver Homeostasis
Frontiers in Physiology, 2017 Polyploidy, the existence of cells containing more than one pair of chromosomes, is a well-known feature of mammalian hepatocytes. Polyploid hepatocytes are found either as cells with a single polyploid nucleus or as multinucleated cells with diploid or ...

First Gynogenesis of Vanilla planifolia for Haploid Production and Ploidy Verification Protocol
PlantsVanilla orchids are members of the Vanilloideae orchid subfamily, and they hold significant economic value as a spice crop in tropical regions. Despite the presence of 180 known species within this subfamily, commercial production focuses on only three ...

ploidyNGS: Visually exploring ploidy with Next Generation Sequencing data
bioRxiv, 2016 Summary ploidyNGS is a model-free, open source tool to visualize and explore ploidy levels in a newly sequenced genome, exploiting short read data. We tested ploidyNGS using both simulated and real NGS data of the model yeast Saccharomyces cerevisiae ...
