Microbial drivers of root plasticity

open access: yesNew Phytologist, Volume 248, Issue 1, Page 52-67, October 2025.
Summary Soils are highly heterogeneous and dynamic systems, experiencing a constant flow of plant root exudates and moisture fluctuations that affect nutrient distribution, soil physicochemical properties, and microbial metabolisms. Plant roots adjust their development within the soil matrix (growth, branching, root angle, and anatomical features) by ...

Microbial biomass and activity in litter during the initial development of pure and mixed plantations of Eucalyptus grandis and Acacia mangium

open access: yesRevista Brasileira de Ciência do Solo, 2013
Studies on microbial activity and biomass in forestry plantations often overlook the role of litter, typically focusing instead on soil nutrient contents to explain plant and microorganism development. However, since the litter is a significant source of

Antibiotic‐Induced Dysbiosis of the Gut Microbiota Shifts Host Tryptophan Metabolism and Increases the Susceptibility of Mice to Pulmonary Infection With Pseudomonas aeruginosa

open access: yesImmunology, Volume 175, Issue 4, Page 453-466, August 2025.
Antibiotic‐induced dysbiosis of the gut microbiota shifts host tryptophan metabolism and impairs the innate immune response during Pseudomonas aeruginosa pulmonary infection. (A) Eubiosis: During eubiosis, the intestinal microbiota metabolises tryptophan into indole metabolites, which keeps tryptophan levels within normal serum concentrations. However,

Proteins and peptides as antigen candidates for the immunodiagnosis of hepatitis D

open access: yesAmino Acids
Designing innovative, accurate, universal, and accessible diagnostic tests is mandatory to improve screening, prevention, and management of hepatitis D (HD), especially in endemic areas with poor infrastructure and restricted access to public health care.

Land Use Change Consistently Reduces α‐ But Not β‐ and γ‐Diversity of Bees

open access: yesGlobal Change Biology, Volume 31, Issue 1, January 2025.
We analyzed a global dataset of 3117 bee assemblages across 157 studies to assess how bee diversity varies among natural, agricultural, and urban habitats. We measured diversity using both the number of bee taxa (taxonomic diversity) and their evolutionary relationships (phylogenetic diversity).

Plant Antimicrobial Peptides and Their Main Families and Roles: A Review of the Literature

open access: yesCurrent Issues in Molecular Biology
Antimicrobial peptides (AMPs) are constituent molecules of the innate defense system and are naturally produced by all organisms. AMPs are characterized by a relatively low molecular weight (less than 10 kDa) and a variable number of cysteine residues ...

Descrição e fatores modeladores da dieta e ecologia da alimentação de girinos neotropicais: Um estudo de caso e uma revisão abrangente

open access: yesAustral Ecology, Volume 49, Issue 1, January 2024.
Resumo Os girinos são componentes importantes de muitas teias alimentares aquáticas, pois influenciam as populações em outros níveis tróficos e, consequentemente, a transferência de energia entre os ecossistemas aquáticos e terrestres. O que os girinos consomem é um fator chave para suas funções ecológicas. As assembleias de anuros neotropicais incluem

WORLDWIDE GENETIC POLYMORPHISM OF CIRCUMSPOROZOITE PROTEIN IN PLASMODIUM VIVAX SEQUENCES: A SYSTEMATIC REVIEW

open access: yesBrazilian Journal of Infectious Diseases
The Circumsporozoite Protein of Plasmodium vivax (PvCSP) is an immunodominant antigen expressed on the surface of the sporozoite. PvCSP consists of a central repetitive region (CRR), capable of stimulating both T and B lymphocytes.

Microrganismos anaeróbios

open access: yes, 2021
Anaerobic bacteria and the infections they cause have had their ups and downs in medical history and are often overlooked, especially at the time of the discovery of antibiotics. Later, as new resistance develops, they will be considered clinically relevant.
