Circular RNAs in Lotus japonicus Responses to Nutrient Supply and Mesorhizobium Symbiosis

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Symbiotic interactions between legumes and rhizobia enable nitrogen fixation under low nutrient conditions. The establishment and function of symbiotic interactions require coordinated changes in gene expression in both the host and the microbe. Circular RNAs (circRNAs) are endogenous gene‐specific molecules that can regulate transcription and

Two distinct conformations of rat liver ribosomal 5S RNA [PDF]

open access: yesNucleic Acids Research, 1982
Three different conformers of rat liver 5S ribosomal RNA were investigated by partial nuclease cleavage technique using S1 nuclease and cobra venom endoribonuclease (CVE) as conformational probes. Urea-treated and renatured 5S RNA co-migrate on non-denaturing gels, but exhibit distinct differences in their nuclease cleavage patterns. The most prominent

RAD51 and RAD51 paralog inhibition sensitizes nonreplicating quiescent keratinocytes to UV radiation

open access: yesPhotochemistry and Photobiology, EarlyView.
UV radiation and other compounds generate DNA adducts that block transcription and induce cell death if not removed by the nucleotide excision repair system. In this work, we used a small‐scale pharmacological screen to discover that inhibition of the recombinase RAD51 sensitized nonreplicating quiescent keratinocytes to both UVR and other agents that ...

Highly heterozygous Citrus changshan‐huyou Y. B. Chang originated from ancient hybridization between mandarin and pummelo and displayed distinct tissue‐specific allelic imbalance

open access: yesThe Plant Genome, Volume 19, Issue 2, June 2026.
Abstract The genus Citrus is characterized by a reticulate evolutionary history with frequent hybridization, making it an intriguing subject for genome evolution investigation. Citrus changshan‐huyou Y. B. Chang (Huyou) is a unique landrace first discovered in Zhejiang Province, China, with premium fruit quality.

FISH mapping and molecular organization of the major repetitive sequences of tomato [PDF]

open access: yes, 2008
This paper presents a bird's-eye view of the major repeats and chromatin types of tomato. Using fluorescence in-situ hybridization (FISH) with Cot-1, Cot-10 and Cot-100 DNA as probes we mapped repetitive sequences of different complexity on pachytene ...

Environmental Stress Induces Altered Composition of Streptococcus mutans Membrane Vesicles: pH‐Driven Changes in Membrane Vesicle Production and Composition

open access: yesMolecular Oral Microbiology, Volume 41, Issue 3, Page 145-157, June 2026.
ABSTRACT Bacteria produce membrane vesicles (MVs) in response to environmental stress and genetic changes. Previous studies have shown that MVs can trigger inflammatory responses and may serve as important mediators of host–microbe interactions. Given the dynamic nature of the oral microbiome, bacteria such as Streptococcus mutans are frequently ...

Ribosomal DNA localization on Lathyrus species chromosomes by FISH

open access: yesJournal of Genetic Engineering and Biotechnology, 2020
Background Fluorescence In Situ Hybridization (FISH) played an essential role to locate the ribosomal RNA genes on the chromosomes that offered a new tool to study the chromosome structure and evolution in plant. The 45S and 5S rRNA genes are independent

Regulation of virulence in Francisella tularensis by small non-coding RNAs [PDF]

open access: yes, 2011
Using a cDNA cloning and sequencing approach we have shown that Francisella tularensis expresses homologues of several small RNAs (sRNAs) that are well-conserved among diverse bacteria.

Comparative Chloroplast Genomics of Cousinia (Asteraceae) With Nine Newly Sequenced Endemic Species From Central Asia

open access: yesEcology and Evolution, Volume 16, Issue 5, May 2026.
In this study, nine complete chloroplast genomes of Cousinia species endemic to the Pamir–Alay mountain system were sequenced and analyzed together with previously published plastomes and nuclear ribosomal ITS data. ABSTRACT Cousinia (Asteraceae: Cardueae) represents one of the most species‐rich genera within the Irano–Turanian floristic region, yet ...
