The problem of the eukaryotic genome size [PDF]
Biochemistry (Moscow), 2008 The current state of knowledge concerning the unsolved problem of the huge interspecific eukaryotic genome size variations not correlating with the species phenotypic complexity (C-value enigma also known as C-value paradox) is reviewed. Characteristic features of eukaryotic genome structure and molecular mechanisms that are the basis of genome size ...

Genome size evolution in macroparasites
International Journal for Parasitology, 2015Reduction in genome size has been associated not only with a parasitic lifestyle in intracellular microparasites but also in some macroparasitic insects and nematodes. We collected the available data on genome size for flatworms, annelids, nematodes and arthropods, compared those with available data for the phylogenetically closest free-living taxa and

Chromosoma, 1972
Nuclear DNA amounts of fifteen species of placental mammals were determined by Feulgen cytophotometry. Relative values for several widely used species have been ascertained with an error of only a few percent. Absolute values (picograms or numbers of nucleotide pairs) can be determined with an error of about ten percent.

Plant Systematics and Evolution, 1986
The DNA 2C and per chromosome values of 57 species belonging to 22 genera of gymnosperms have been analysed. The overall range is 12-fold with a modal value of about 30.0 pg.Cycadales exhibit a 2-fold difference. AmongConiferales with a 4-fold variation, thePinaceae have higher mean DNA contents as well as a greater range and diversity than other ...

Chromosoma, 1972
Nuclear DNA amounts of twenty-three species of birds from seventeen families of seven orders were determined by Feulgen cytophotometry. Genome size is constant in these birds, the ratio between the largest and smallest genome in the sample is 1.3 to 1.

On the Evolution of Genome Size of Birds
Journal of Heredity, 1991We measured genome size (nuclear DNA content) by fluorescence flow cytometry in 55 species of birds representing 12 different orders. Similar studies were performed in approximately 100 species by laboratories using absorption cytophotometry of Feulgen-stained nuclei.

Genome Size of Mycoplasmal DNA
Nature, 1969ELECTRON microscopic studies of the contour length of DNA from a mycoplasma species, Mycoplasma hominis (H 39)1, have shown that the DNA in this organism is organized in a single circular chromosome, 262 microns long, corresponding to a molecular weight of 5.0 × 108 daltons.

Land plant species (Embryophyta) vary more than 2,300-fold in the size of the holoploid genome (C-value) (see Leitch and Leitch 2012a, this volume) with the extremes at both ends of the scale contributed by angiosperms. At the lower end we find some species of the carnivorous Lentibulariaceae with ultrasmall genomes, e.g.

Estimation of genome sizes of hyperthermophiles
Extremophiles, 1998Genomes of various hyperthermophilic and extremely thermophilic prokaryotes were analyzed with respect to size, physical organization, and 16S rDNA copy number. Our results show that all the genomes are circular, and they are in the size range of 1.6-1.8 Mb for Pyrodictium abyssi, Methanococcus igneus, Pyrobaculum aerophilum, Archaeoglobus fulgidus ...

Genome size and longevity in fish
Experimental Gerontology, 2003The wide variety of genome sizes (measured as C-value) observed across taxa is not related to organismal complexity or number of coding genes. Partial answers to this C-value enigma have been found by establishing associations between C-value and particular phenotypic characteristics.
