The retrohoming of linear group II intron RNAs in Drosophila melanogaster occurs by both DNA ligase 4-dependent and -independent mechanisms. [PDF]
Mobile group II introns are bacterial retrotransposons that are thought to have invaded early eukaryotes and evolved into introns and retroelements in higher organisms.

The trouble with (group II) introns [PDF]
Qu et al. provide new grist for the introns origin mill (1), adding one more chapter to what has become a very long narrative. Back in the day when spliceosomal introns in the protein-coding genes of eukaryotes were still very new to science (1977–1978), some of us argued that—in an evolutionary sense—they were actually very old (2, 3).

Natural circularly permuted group II introns in bacteria produce RNA circles
Summary: Group II self-splicing introns are large structured RNAs that remove themselves from transcripts while simultaneously sealing the resulting gaps.

Using Group II Introns for Attenuating the In Vitro and In Vivo Expression of a Homing Endonuclease. [PDF]
In Chaetomium thermophilum (DSM 1495) within the mitochondrial DNA (mtDNA) small ribosomal subunit (rns) gene a group IIA1 intron interrupts an open reading frame (ORF) encoded within a group I intron (mS1247).

Maturases can specifically bind to intron-containing pre-RNAs, folding them into catalytic structures that facilitate intron splicing in vivo. Plants possess four nuclear-encoded maturase-related factors (nMAT1-nMAT4) and some maturases have been shown ...

Genetic and biochemical assays reveal a key role for replication restart proteins in group II intron retrohoming. [PDF]
Mobile group II introns retrohome by an RNP-based mechanism in which the intron RNA reverse splices into a DNA site and is reverse transcribed by the associated intron-encoded protein.

Mechanisms used for genomic proliferation by thermophilic group II introns. [PDF]
Mobile group II introns, which are found in bacterial and organellar genomes, are site-specific retroelements hypothesized to be evolutionary ancestors of spliceosomal introns and retrotransposons in higher organisms.

Next-generation RNA-sequencing (RNA-seq) has revolutionized transcriptome profiling, gene expression analysis, and RNA-based diagnostics. Here, we developed a new RNA-seq method that exploits thermostable group II intron reverse transcriptases (TGIRTs ...

RNA-seq of human reference RNA samples using a thermostable group II intron reverse transcriptase
Next-generation RNA sequencing (RNA-seq) has revolutionized our ability to analyze transcriptomes. Current RNA-seq methods are highly reproducible, but each has biases resulting from different modes of RNA sample preparation, reverse transcription, and ...

Bacterial group II introns: not just splicing [PDF]
Group II introns are both catalytic RNAs (ribozymes) and mobile retroelements that were discovered almost 14 years ago. It has been suggested that eukaryotic mRNA introns might have originated from the group II introns present in the alphaproteobacterial progenitor of the mitochondria.
