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.

Exon-intron structure and sequence variation of the calreticulin gene among Rhipicephalus sanguineus group ticks [PDF]
Background: Calreticulin proteins (CRTs) are important components of tick saliva, which is involved in the blood meal success, pathogen transmission and host allergic responses.

DNA-based S-genotyping of Japanese plum and pluot cultivars to clarify incompatibility relationships [PDF]
Diploid japanese plum (Prunus salicina Lindl.) cultivars are commonly self-incompatible. To date, 14 incompatibility alleles (S-alleles) have been identified and labeled with alphabetical (S-a-S-n) and 5 with numeric codes (S-1, S-3-S-6).

Global Regulators Orchestrate Group II Intron Retromobility [PDF]
Group II introns are hypothesized to share common ancestry with both nuclear spliceosomal introns and retrotransposons, which collectively occupy the majority of genome space in higher eukaryotes. These phylogenetically diverse introns are mobile retroelements that move through an RNA intermediate.

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.

Mitochondrial and chloroplast DNA-based phylogeny of Pelargonium (Geraniaceae) [PDF]
Overall phylogenetic relationships within the genus Pelargonium (Geraniaceae) were inferred based on DNA sequences from mitochondrial(mt)-encoded nad1 b/c exons and from chloroplast(cp)-encoded trnL (UAA) 5' exon-trnF (GAA) exon regions using two species

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 ...
