Introns in Cryptococcus [PDF]

Memorias do Instituto Oswaldo Cruz, 2018
In Cryptococcus neoformans, nearly all genes are interrupted by small introns. In recent years, genome annotation and genetic analysis have illuminated the major roles these introns play in the biology of this pathogenic yeast.

The peculiarities of large intron splicing in animals. [PDF]

PLoS ONE, 2009
In mammals a considerable 92% of genes contain introns, with hundreds and hundreds of these introns reaching the incredible size of over 50,000 nucleotides.

Both size and GC-content of minimal introns are selected in human populations. [PDF]

PLoS ONE, 2011
BACKGROUND: We previously have studied the insertion and deletion polymorphism by sequencing no more than one hundred introns in a mixed human population and found that the minimal introns tended to maintain length at an optimal size. Here we analyzed re-

Sense-antisense gene overlap is probably a cause for retaining the few introns in Giardia genome and the implications

Biology Direct, 2018
Background It is widely accepted that the last eukaryotic common ancestor and early eukaryotes were intron-rich and intron loss dominated subsequent evolution, thus the presence of only very few introns in some modern eukaryotes must be the consequence ...

Cyanobacterial ribosomal RNA genes with multiple, endonuclease-encoding group I introns

BMC Evolutionary Biology, 2007
Background Group I introns are one of the four major classes of introns as defined by their distinct splicing mechanisms. Because they catalyze their own removal from precursor transcripts, group I introns are referred to as autocatalytic introns.

Proposal of a new nomenclature for introns in protein-coding genes in fungal mitogenomes

IMA Fungus, 2019
Fungal mitochondrial genes are often invaded by group I or II introns, which represent an ideal marker for understanding fungal evolution. A standard nomenclature of mitochondrial introns is needed to avoid confusion when comparing different fungal ...

Unique features of conventional and nonconventional introns in Euglena gracilis

BMC Genomics
Background Nuclear introns in Euglenida have been understudied. This study aimed to investigate nuclear introns in Euglenida by identifying a large number of introns in Euglena gracilis (E.

Introns increase gene expression in Caenorhabditis elegans by a mechanism that must be at least partly different than in plants

Scientific Reports
The wide diversity of organisms in which introns stimulate gene expression suggests that this is an ancient phenomenon. However, the mechanisms through which introns boost expression remain poorly understood, and the degree the which the action of ...

U12-type Spliceosomal Introns of Insecta

International Journal of Biological Sciences, 2012
Most of eukaryotic genes are interrupted by introns that need to be removed from pre-mRNAs before they can perform their function. This is done by complex machinery called spliceosome.
