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

Phylogenetic Utility of rRNA ITS2 Sequence-Structure under Functional Constraint [PDF]

International Journal of Molecular Sciences, 2020
The crucial function of the internal transcribed spacer 2 (ITS2) region in ribosome biogenesis depends on its secondary and tertiary structures. Despite rapidly evolving, ITS2 is under evolutionary constraints to maintain the specific secondary structures that provide functionality.

Resource Allocation Trade‐Offs and Rewired Mycorrhizal Networks Underlie the Adaptation of Paphiopedilum purpuratum to Ex Situ Conservation

Biological Diversity, EarlyView.
Paphiopedilum purpuratum Mediates Adaptation via a Dual‐Fungal Strategy: Confronting a physiological trade‐off (↑seed set vs. ↓photosynthesis), Paphiopedilum purpuratum restructures its root microbiome. Mycorrhizal fungi stabilize into a resilient core network, whereas non‐mycorrhizal fungi shift to a dynamic beneficial periphery.

Pan-eukaryote ITS2 homologies revealed by RNA secondary structure [PDF]

Nucleic Acids Research, 2007
For evolutionary comparisons, phylogenetics and evaluation of potential interbreeding taxa of a species, various loci have served for animals and plants and protistans. One [second internal transcribed spacer (ITS2) of the nuclear ribosomal DNA] is highly suitable for all. Its sequence is species specific.

USING sma-its2 PRIMER FOR ITS2 (Internal Transcribed Spacer-2)-BASED MOLECULAR CHARACTERIZATION OF Anopheles minimus FROM KULONPROGO, YOGYAKARTA - INDONESIA

BIOEDUKASI, 2022
Malaria is a public health threat caused by the Plasmodium infection transmitted by the Anopheles mosquito. Malaria vector control is highly dependent on the ability to determine mosquito species' vectorial and bionomic capacity. Species identification based on morphological characteristics as well as DNA-barcoding approaches is a very important step ...

Arbuscular mycorrhizal fungal community abundance, functions, and symbiotic interactions revealed by root metatranscriptomes

iMetaOmics, EarlyView.
Paradigm shift: PCR‐free methods reveal 6–15‐fold higher arbuscular mycorrhizal (AM) fungal abundance than metabarcoding, exposing systematic underestimation across decades of research. Predictive power: AM fungal abundance serves as a community‐level trait that predicts crop yield under drought conditions.

Comparative analysis of fungal microbiomes in Korean and Chinese chili pepper powders

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Chili pepper powder plays a crucial role in kimchi fermentation; however, its use may result in fungal contamination. Therefore, analyzing its mycobiome is vital to maintain quality control standards. In this study, we used internal transcribed spacer (ITS)2 amplicon sequencing to compare fungal communities in commercially available

Molecular phylogenetic and morphological analyses revealed a new species, Leucocoprinus roseus (Agaricaceae, Basidiomycota), from Punjab, Pakistan

Nordic Journal of Botany, EarlyView.
In this article, we describe a new fungal species, Leucocoprinus roseus, collected in Canal View Park, District Mandi Bahauddin, Punjab, Pakistan. The species is proposed as new based on detailed morphological observations and molecular phylogenetic analysis using nuclear ribosomal DNA internal transcribed spacer (nrITS) sequences.

Sedum zhenghaianum (Crassulaceae), a new species from Zhejiang and Jiangxi, East China

Nordic Journal of Botany, EarlyView.
In this paper, Sedum zhenghaianum sp. nov. is described as a new species based on morphological and molecular analyses, and its taxonomic relationships are discussed. Morphological analysis indicates that S. zhenghaianum should be classified in the genus Sedum sect. Sedum and is distinct from the related species S. tosaense in morphology, e.g.

Variation in Symbiodinium ITS2 Sequence Assemblages among Coral Colonies

PLoS ONE, 2011
Endosymbiotic dinoflagellates in the genus Symbiodinium are fundamentally important to the biology of scleractinian corals, as well as to a variety of other marine organisms. The genus Symbiodinium is genetically and functionally diverse and the taxonomic nature of the union between Symbiodinium and corals is implicated as a key trait determining the ...
