Defining the location of promoter-associated R-loops at near-nucleotide resolution using bisDRIP-seq

eLife, 2017
R-loops are features of chromatin consisting of a strand of DNA hybridized to RNA, as well as the expelled complementary DNA strand. R-loops are enriched at promoters where they have recently been shown to have important roles in modifying gene ...

Comparative Genomics Analysis of Ciliates Provides Insights on the Evolutionary History Within “Nassophorea–Synhymenia–Phyllopharyngea” Assemblage

Frontiers in Microbiology, 2019
Ciliated protists (ciliates) are widely used for investigating evolution, mostly due to their successful radiation after their early evolutionary branching.

The mitogenomes of Leptographium aureum, Leptographium sp., and Grosmannia fruticeta: expansion by introns

Frontiers in Microbiology, 2023
IntroductionMany members of the Ophiostomatales are of economic importance as they are bark-beetle associates and causative agents for blue stain on timber and in some instances contribute towards tree mortality.

Horizontal Transfer and Gene Loss Shaped the Evolution of Alpha-Amylases in Bilaterians

G3: Genes, Genomes, Genetics, 2020
The subfamily GH13_1 of alpha-amylases is typical of Fungi, but it is also found in some unicellular eukaryotes (e.g., Amoebozoa, choanoflagellates) and non-bilaterian Metazoa.

The Cancer Spliceome: Reprograming of Alternative Splicing in Cancer

Frontiers in Molecular Biosciences, 2018
Alternative splicing allows for the expression of multiple RNA and protein isoforms from one gene, making it a major contributor to transcriptome and proteome diversification in eukaryotes.

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. However, no intron-devoidy east species have been identified and some of the introns remaining within the genomes of ...

Periodicities in introns

Nucleic Acids Research, 1987
The sequence information for the splicing process of introns is found in the consensus sequences at the two splice sites. For long introns, of 300 or more nucleotides, the middle regions may provide additional specificity for splicing which can be investigated by defining an adequate quantitative parameter.

Mitochondrial genomes of the early land plant lineage liverworts (Marchantiophyta): conserved genome structure, and ongoing low frequency recombination

BMC Genomics, 2019
Background In contrast to the highly labile mitochondrial (mt) genomes of vascular plants, the architecture and composition of mt genomes within the main lineages of bryophytes appear stable and invariant.

Effect of introns and AT-rich sequences on expression of the bacterial hygromycin B resistance gene in the basidiomycete Schizophyllum commune

, 2001
Previously, it was shown that introns are required for efficient mRNA accumulation in Schizophyllum commune and that the presence of AT-rich sequences in the coding region of genes can result in truncation of transcripts in this homobasidiomycete.
