Genome and cell size responses to temperature in ectotherms [PDF]

open access: yes, 2013
The relationship between temperature and body size has attracted wide interest since the “Bergmann's rule” was introduced. While this rule originally dealt with endotherms, later studies have focussed ectotherms, including cell- and genome sizes. Because

Disentangling Crocus Series Verni and Its Polyploids

open access: yesBiology, 2023
Spring crocuses, the eleven species within Crocus series Verni (Iridaceae), consist of di- and tetraploid cytotypes. Among them is a group of polyploids from southeastern Europe with yet-unclear taxonomic affiliation. Crocuses are generally characterized

Genome size versus genome assemblies: Are the genomes truly expanded in polyploid fungal symbionts?

open access: yes, 2020
Each day, as the amount of genomic data and bioinformatics resources grows, researchers are increasingly challenged with selecting the most appropriate approach to analyze their data. In addition, the opportunity to undertake comparative genomic analyses

Ubiquitous selective constraints in the Drosophila genome revealed by a genome-wide interspecies comparison [PDF]

open access: yes, 2006
Non-coding DNA comprises ∼80% of the euchromatic portion of the Drosophila melanogaster genome. Non-coding sequences are known to contain functionally important elements controlling gene expression, but the proportion of sites that are selectively ...

Causes and Effects of Loss of Classical Nonhomologous End Joining Pathway in Parasitic Eukaryotes

open access: yesmBio, 2019
We report frequent losses of components of the classical nonhomologous end joining pathway (C-NHEJ), one of the main eukaryotic tools for end joining repair of DNA double-strand breaks, in several lineages of parasitic protists.

A Flow Cytometry-Based Assessment of the Genomic Size and Ploidy Level of Wild Musa Species in India

open access: yesPlants, 2023
The genome size variation is an important attribute in evolutionary and species characterization. Musa L. is regarded as one of the taxonomically complicated genera within the order Zingiberales, with more than 75 species from wild seeded to seedless ...

Comparative cytogenetic analysis of diploid and hexaploid Chenopodium album Agg

open access: yesActa Societatis Botanicorum Poloniae, 2011
Two cytotypes of Chenopodium album, diploid (2n=2x=18) and hexaploid (2n=6x=54), were analysed using flow cytometry and a FISH experiment. The genome size was indicated as 1.795 pg for the diploid and 3.845 pg for the hexaploid plants which suggested ...
