Vegetal residue‐based formulation of Trichoderma ossianense, a new indigenous vineyard species adapted to alkaline pH with potential biocontrol ability against Black‐foot disease pathogens

Pest Management Science, EarlyView.
The study identifies Trichoderma ossianense, was can be isolated from grapevine roots, is capable of growing at alkaline pH and controls black‐foot pathogens, highlighting the vegetal residue‐based formulations that preserve its viability. Abstract BACKGROUND Fungi of the Trichoderma genus are used in vineyards as biological control agents mainly ...

RNA polymerase II-mediated rDNA transcription mediates rDNA copy number expansion in Drosophila

PLOS Genetics
Ribosomal DNA (rDNA), which encodes ribosomal RNA, is an essential but unstable genomic element due to its tandemly repeated nature. rDNA’s repetitive nature causes spontaneous intrachromatid recombination, leading to copy number (CN) reduction, which must be counteracted by a mechanism that recovers CN to sustain cells’ viability.

Potential of bacteria isolated from chitin‐enriched soil against Euschistus heros (Hemiptera: Pentatomidae)

Pest Management Science, EarlyView.
B. thuringiensis and B. altitudinis, isolated from chitin‐enriched soil, causing mortality in Euchistus heros under laboratory conditions. First report of B. altitudinis in the control of E. heros. Abstract BACKGROUND Biological control using entomopathogenic microorganisms is a more sustainable alternative to chemical pesticides for managing insect ...

Glucosinolate hydrolysis products suppress entomopathogenic nematodes in vitro but do not protect sequestering flea beetle larvae in vivo

Pest Management Science, EarlyView.
The flea beetle's glucosinolate‐based chemical defense fails to protect larvae from nematode infection. However, the defense inhibits the nematode's symbiotic bacteria, thereby potentially impairing nematode reproduction and biocontrol success. Abstract BACKGROUND The efficacy of entomopathogenic nematodes (EPNs) in the biological control of insect ...

Increased Ribosome Biogenesis and Increased Oxidative Stress in Blood Leukocytes of Patients With Catatonic Schizophrenia Compared With Paranoid Schizophrenia

Frontiers in Bioscience-Landmark
Background: Schizophrenia (SZ) is associated with chronic oxidative stress in the patient’s body. Previous studies revealed an increased copy number of genes for 47S pre-ribosomal RNA (pre-rRNA) in SZ patients. In this study, levels of

Cytogenetic relationships within the Maghrebian clade of Festuca subgen. Schedonorus (Poaceae), using flow cytometry and FISH

Anales del Jardín Botánico de Madrid, 2017
Festuca subgen. Schedonorus is a group of broad-leaved fescues, which can be divided into two clades: European and Maghrebian. We employed fluorescent in situ hybridization —FISH— with probes specific for 5S and 35S ribosomal DNA and genome size ...

Distinct Nasal Microbiome Profiles and Prediction Model for Allergic Rhinitis, Nonallergic Rhinitis, and Healthy Children

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
The alpha and beta diversity of the nasal microbiome differed among children with allergic rhinitis (AR), nonallergic rhinitis (NAR), and healthy controls (HCs). Compared to HC, AR had more Escherichia‐Shigella, Negativicoccus, and Campylobacter, while NAR had more Dolosigranulum and fewer Enterobacteriaceae.

macroH2A1 histone variant represses rDNA transcription

Nucleic Acids Research, 2013
The regulation of ribosomal DNA transcription is an important step for the control of cell growth. Epigenetic marks such as DNA methylation and posttranslational modifications of canonical histones have been involved in this regulation, but much less is known about the role of histone variants.

DNA metabarcoding reveals wolf dietary patterns in the northern Alps and Jura Mountains

Wildlife Biology, EarlyView.
Understanding predator–prey interactions is crucial for wildlife management and human–wildlife coexistence, particularly in multi‐use landscapes such as western Europe. As wolves Canis lupus recolonize their former habitats, knowledge of their diet is essential for conservation, management and public acceptance.
