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.

Intron Evolution in Saccharomycetaceae [PDF]
Genome Biology and Evolution, 2014 Introns in protein-coding genes are very rare in hemiascomycetous yeast genomes. It has been suggested that these species have experienced extensive intron loss during their evolution from the postulated intron-rich fungal ancestor.

Plant intron sequences: evidence for distinct groups of introns [PDF]
Nucleic Acids Research, 1988 In vivo and in vitro RNA splicing experiments have demonstrated that the intron splicing machineries are not interchangeable in all organisms. These differences have prevented the efficient in vivo expression of monocot genes containing introns in dicot plants and the in vitro excision of some plant introns in HeLa cell in vitro splicing extracts.

Minor intron retention drives clonal hematopoietic disorders and diverse cancer predisposition
Nature Genetics, 2021 Most eukaryotes harbor two distinct pre-mRNA splicing machineries: the major spliceosome, which removes >99% of introns, and the minor spliceosome, which removes rare, evolutionarily conserved introns.

Frontiers in Genetics, 2012 The intron-exon architecture of many eukaryotic genes raises the intriguing question of whether this unique organization serves any function, or is it simply a result of the spread of functionless introns in eukaryotic genomes. In this review, we show that introns in contemporary species fulfill a broad spectrum of functions, and are involved in ...

Introns: The Functional Benefits of Introns in Genomes [PDF]
Genomics & Informatics, 2015 The intron has been a big biological mystery since it was first discovered in several aspects. First, all of the completely sequenced eukaryotes harbor introns in the genomic structure, whereas no prokaryotes identified so far carry introns. Second, the amount of total introns varies in different species. Third, the length and number of introns vary in

Molecular Biotechnology, 2011 Eukaryotic gene expression relies on several complex molecular machineries that act in a highly coordinated fashion. These machineries govern all the different steps of mRNA maturation, from gene transcription and pre-mRNA processing in the nucleus to the export of the mRNA to the cytoplasm and its translation.

Intron “sliding” and the diversity of intron positions [PDF]
Proceedings of the National Academy of Sciences, 1997 Alignments of homologous genes typically reveal a great diversity of intron locations, far more than could fit comfortably in a single gene. Thus, a minority of these intron positions could be inherited from a single ancestral gene, but the larger share must be attributed to subsequent events of intron gain or intron “sliding” (movement from one ...

The insertion of a mitochondrial selfish element into the nuclear genome and its consequences
Ecology and Evolution, 2020 Homing endonucleases (HE) are enzymes capable of cutting DNA at highly specific target sequences, the repair of the generated double‐strand break resulting in the insertion of the HE‐encoding gene (“homing” mechanism).

RHD Genotypes in a Chinese Cohort of Pregnant Women
Frontiers in Genetics, 2021 RHD variants in D¯ Chinese pregnant women arose difficulties in management during pregnancy. Therefore, this study aims to precisely manage D¯ pregnant women by evaluating the spectrum of RHD mutations in D¯ pregnant women and getting insight into the ...
