Introns do grupo I no mitogenoma de fungos: aspectos evolutivos e sua relevância na micologia médica
(Universidade Federal do Rio Grande do NorteBrasilUFRNBiomedicina, 2021-04-23)
Group I introns (IGI) are small RNAs (250-500 nt) capable of catalysing their own splicing from the precursor RNA. They are widely distributed across the tree of life and have intricate relationships with their host genomes. ...
Sequence features responsible for intron retention in human
(2007)
Abstract
Background
One of the least common types of alternative splicing is the complete retention of an intron in a mature ...
Frequent, phylogenetically local horizontal transfer of the cox1 group I intron in flowering plant mitochondria
(Oxford University Press, 2008-06)
Horizontal gene transfer is surprisingly common among plant mitochondrial genomes. The first well-established case involves a homing group I intron in the mitochondrial cox1 gene shown to have been frequently acquired via ...
Multiple recent horizontal transfers of the cox1 intron in Solanaceae and extended co-conversion of flanking exons
(BioMed Central, 2011-09)
Background: The most frequent case of horizontal transfer in plants involves a group I intron in the mitochondrial gene cox1, which has been acquired via some 80 separate plant-to-plant transfer events among 833 diverse ...
Polymorphism in Mitochondrial Group I Introns among Cryptococcus neoformans and Cryptococcus gattii Genotypes and Its Association with Drug Susceptibility
(Frontiers Media Sa, 2018-02-06)
Cryptococcosis, one of the most important systemic mycosis in the world, is caused by different genotypes of Cryptococcus neoformans and Cryptococcus gattii, which differ in their ecology, epidemiology, and antifungal ...
Genome mapping and expression analyses of human intronic noncoding RNAs reveal tissue-specific patterns and enrichment in genes related to regulation of transcription
(2007)
Abstract
Background
RNAs transcribed from intronic regions of genes are involved in a number of processes related to post-transcriptional control of gene expression. However, the ...
Adh1 first intron polymorphisms in Argentinean populations of Ceratitis capitata
(2010-07)
DNA size polymorphisms were utilized in a study of 24 natural populations of Ceratitis capitata Wiedemann
(Diptera: Tephritidae) from Argentina. The first intron of alcohol dehydrogenase 1 gene
(Adh1) was amplified using ...
Environmental stresses inhibit splicing in the aquatic fungus Blastocladiella emersonii
(BIOMED CENTRAL LTD, 2009)
Background: Exposure of cells to environmental stress conditions can lead to the interruption of several intracellular processes, in particular those performed by macromolecular complexes such as the spliceosome. Results: ...
First come, first served revisited: Factors affecting the same alternative splicing event have different effects on the relative rates of intron removal
(Cold Spring Harbor Laboratory Press, 2010-05)
Alternative splicing accounts for much of the complexity in higher eukaryotes. Thus, its regulation must allow for flexibility without hampering either its specificity or its fidelity. The mechanisms involved in alternative ...
