Mapping-based genome size estimation [PDF]

open access: yesBMC Genomics, 2019
While the size of chromosomes can be measured under a microscope, obtaining the exact size of a genome remains a challenge. Biochemical methods and k-mer distribution-based approaches allow only estimations. An alternative approach to estimate the genome

Genome size variation and polyploidy prevalence in the genus Eragrostis are associated with the global dispersal in arid area [PDF]

open access: goldFrontiers in Plant Science, 2023
BackgroundBiologists have long debated the drivers of the genome size evolution and variation ever since Darwin. Assumptions for the adaptive or maladaptive consequences of the associations between genome sizes and environmental factors have been ...

Genome size versus geographic range size in birds [PDF]

open access: yesPeerJ, 2021
Why do some species occur in small, restricted areas, while others are distributed globally? Environmental heterogeneity increases with area and so does the number of species.

Centromere size scales with genome size across Eukaryotes [PDF]

open access: yesScientific Reports, 2021
Previous studies on grass species suggested that the total centromere size (sum of all centromere sizes in a cell) may be determined by the genome size, possibly because stable scaling is important for proper cell division. However, it is unclear whether

Does Cell Size Impact Chloroplast Genome Size? [PDF]

open access: yesFrontiers in Plant Science, 2017
There is a strong positive relationship between nuclear genome size and cell size across the eukaryotic domain, but the cause and effect of this relationship is unclear.

Morphological and Genome-Wide Evidence of Homoploid Hybridisation in Urospermum (Asteraceae)

open access: yesPlants, 2022
The genus Urospermum is distributed in the Mediterranean region and Macaronesia, and has been introduced to other extra-Mediterranean regions. Although the two species constituting the genus, U. dalechampii and U. picroides, are frequently found together,

The Evolution of Cytogenetic Traits in Cuscuta (Convolvulaceae), the Genus With the Most Diverse Chromosomes in Angiosperms

open access: yesFrontiers in Plant Science, 2022
Karyotypes are characterized by traits such as chromosome number, which can change through whole-genome duplication and dysploidy. In the parasitic plant genus Cuscuta (Convolvulaceae), chromosome numbers vary more than 18-fold.

Morphological and genome size variations within populations of Edraianthus graminifolius “Jugoslavicus” (Campanulaceae) from the central Balkan peninsula [PDF]

open access: yesArchives of Biological Sciences, 2014
The E. graminifolius complex is widely distributed in the continental part of the central and western Balkan Peninsula and is characterized by pronounced morphological variability.

Eukaryotic genome size databases [PDF]

open access: yesNucleic Acids Research, 2007
Three independent databases of eukaryotic genome size information have been launched or re-released in updated form since 2005: the Plant DNA C-values Database (www.kew.org/genomesize/homepage. html), the Animal Genome Size Database (www. genomesize.com) and the Fungal Genome Size Database (www.zbi.ee/fungal-genomesize/).
