Journal of Visualized Experiments, 2012 The internal transcribed spacer 2 (ITS2) has been used as a phylogenetic marker for more than two decades. As ITS2 research mainly focused on the very variable ITS2 sequence, it confined this marker to low-level phylogenetics only. However, the combination of the ITS2 sequence and its highly conserved secondary structure improves the phylogenetic ...

A database for ITS2 sequences from nematodes [PDF]
BMC Genetics, 2019 Summary Marker gene surveys have a wide variety of applications in species identification, population genetics, and molecular epidemiology. As these methods expand to new types of organisms and additional markers beyond 16S and 18S rRNA genes, comprehensive databases are a critical requirement for proper analysis of these data.

The ITS2 Database III—sequences and structures for phylogeny [PDF]
Nucleic Acids Research, 2009 The internal transcribed spacer 2 (ITS2) is a widely used phylogenetic marker. In the past, it has mainly been used for species level classifications. Nowadays, a wider applicability becomes apparent. Here, the conserved structure of the RNA molecule plays a vital role.

Conservation patterns in angiosperm rDNA ITS2 sequences [PDF]
Nucleic Acids Research, 1996 The two internal transcribed spacers (ITS1 and ITS2) of nuclear ribosomal DNA have become commonly exploited sources of informative variation for interspecific-/intergeneric-level phylogenetic analyses among angiosperms and other eukaryotes. We present an alignment in which one-third to one-half of the ITS2 sequence is alignable above the family level ...

Horticulturae, 2023 (1) Background: The purpose of this study was to compare the free volatile compounds of 18 Veronica species (Plantaginaceae), as previously analyzed by gas chromatography coupled with mass spectrometry, with their DNA sequences for internal transcribed spacers ITS2 and ITS1-5.8S-ITS2 of the nuclear ribosomal DNA.

Conserved secondary structures in the ITS2 of trematode pre‐rRNA [PDF]
FEBS Letters, 1993 Biological functions of transcribed spacer regions in eucaryotic pre‐rRNAs remain elusive so far. Utilization of the comparative approach to analyse their secondary structure has been impeded by the extensive sequence divergence observed among most of the specimens available to date. However, we have taken advantage of the recent derivation of a set of

Holmes-ITS2: Consolidated ITS2 resources and search engines for plant DNA-based marker analyses [PDF]
, 2018 ABSTRACT Plants are valuable resources for a variety of products in modern societies. Plant species identification is an integral part of research and practical application on plants. In parallel with high-throughput sequencing technology, the high-throughput screening of species is in high demand.

Reconstitution of the complete pathway of ITS2 processing at the pre-ribosome [PDF]
Nature Communications, 2017 AbstractRemoval of internal transcribed spacer 2 (ITS2) from pre-ribosomal RNA is essential to make functional ribosomes. This complicated processing reaction begins with a single endonucleolytic cleavage followed by exonucleolytic trimming at both new cleavage sites to generate mature 5.8S and 25S rRNA.
