There are four major classes of introns: self-splicing group I and group II introns, tRNA
and/or archaeal introns and spliceosomal introns in nuclear pre-mRNA. Group I introns are …

Buried within the genomes of many microorganisms are genetic elements that encode rare-
cutting homing endonucleases that assist in the mobility of the elements that encode them …

Fungal mitochondrial (mt) genomes exhibit great diversity in size which is partially attributed
to their variable intergenic regions and most importantly to the inclusion of introns within …

Background The mitochondrial genome of Metazoa is usually a compact molecule without
introns. Exceptions to this rule have been reported only in corals and sea anemones …

The soil fungus Rhizoctonia solani is an economically important pathogen of agricultural
and forestry crops. Here, we present the complete sequence and analysis of the …

All oligonucleotides of the sugarcane chloroplast genome that are conserved in one or more
of 36 other completed plastid genomes have been identified by computer-assisted …

Endoconidiophora resinifera (= Ceratocystis resinifera) is a blue-stain fungus that occurs on
conifers. The data showed that the Endoconidiophora resinifera mitochondrial genome is …

In some ascomycete fungi, ribosomal protein S3 (Rps3) is encoded within a group I intron
(mL2449) that is inserted in the U11 region of the mitochondrial large subunit rDNA (rnl) …

Background Mitochondrial introns intermit coding regions of genes and feature characteristic
secondary structures and splicing mechanisms. In metazoans, mitochondrial introns have …

Group I introns are highly dynamic and mobile, featuring extensive presence-absence
variation and widespread horizontal transfer. Group I introns can invade intron-lacking …
