Taxonomy of introns and the evolution of minor introns

open access: yesNucleic Acids Research
Classification of introns, which is crucial to understanding their evolution and splicing, has historically been binary and has resulted in the naming of major and minor introns that are spliced by their namesake spliceosome.

Analysis of intron sequence features associated with transcriptional regulation in human genes. [PDF]

open access: yesPLoS ONE, 2012
Although some preliminary work has revealed the potential transcriptional regulatory function of the introns in eukaryotes, additional evidences are needed to support this conjecture.

Heterochromatin is enriched in promoter-proximal introns.

open access: yes, 2020
(A) Boxplots for length of normal and heterochromatic introns. Heterochromatic introns are significantly longer than introns without heterochromatic domains (p-value < 2.2e-16, Wilcoxon exact test). (B) (left) Intron position and length for all introns. (

Order of removal of conventional and nonconventional introns from nuclear transcripts of Euglena gracilis. [PDF]

open access: yesPLoS Genetics, 2018
Nuclear genes of euglenids and marine diplonemids harbor atypical, nonconventional introns which are not observed in the genomes of other eukaryotes. Nonconventional introns do not have the conserved borders characteristic for spliceosomal introns or the

The Protist Ribosomal Reference database (PR2): a catalog of unicellular eukaryote Small Sub-Unit rRNA sequences with curated taxonomy [PDF]

open access: yes, 2012
The interrogation of genetic markers in environmental meta-barcoding studies is currently seriously hindered by the lack of taxonomically curated reference data sets for the targeted genes.

Historical fragmentation and stepping‐stone gene flow led to population genetic differentiation in a coastal seabird

open access: yesEcology and Evolution
Understanding the forces that shape population genetic structure is fundamental both for understanding evolutionary trajectories and for conservation. Many factors can influence the geographic distribution of genetic variation, and the extent to which ...

Identification, molecular characterization, and evolution of group I introns at the expansion segment D11 of 28S rDNA inRhizoctonia species [PDF]

open access: yes, 2013
The nuclear ribosomal DNA of Rhizoctonia species is polymorphic in terms of the nucleotide composition and length. Insertions of 349e410 nucleotides in length with characteristics of group I introns were detected at a single insertion point at the ...

Identification of an Exceptionally Long Intron in the HAC1 Gene of Candida parapsilosis

open access: yesmSphere, 2018
The unfolded protein response (UPR) in the endoplasmic reticulum (ER) is well conserved in eukaryotes from metazoa to yeast. The transcription factor HAC1 is a major regulator of the UPR in many eukaryotes. Deleting HAC1 in the yeast Candida parapsilosis

Modeling in yeast how rDNA introns slow growth and increase desiccation tolerance in lichens

open access: yesG3: Genes, Genomes, Genetics, 2021
We connect ribosome biogenesis to desiccation tolerance in lichens, widespread symbioses between specialized fungi (mycobionts) and unicellular phototrophs.
