Characterization and Antifungal Activity of a Hevein-Like Peptide-Containing Extract From <i>Capsicum annuum</i> Leaves Against Phytopathogenic Fungi. [PDF]

open access: yesInt J Microbiol
This study is aimed at isolating and characterizing antimicrobial peptides (AMPs) from the leaves of Capsicum annuum (L.) cv. Carioquinha and investigating their antifungal activity and mechanism of action against phytopathogenic fungi. An initial extract was obtained from leaves through hydromethanolic extraction followed by partitioning with ...

Fire‐induced shifts in activity patterns of predators and prey in the Brazilian Pantanal

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 6, August 2026.
Using camera trap data, we observed that 5 of 6 prey species showed statistically significant changes in temporal activity patterns, while jaguars were the only predator species to adjust activity when comparing pre‐fire and post‐fire periods in an isolated rocky formation in the Pantanal region.

Climate Predicts Tree Dispersal Strategies Across Brazil's Ecosystems

open access: yesGlobal Ecology and Biogeography, Volume 35, Issue 7, July 2026.
ABSTRACT Aim We investigate the distribution of dispersal modes—endozoochory (via animal ingestion), synzoochory (via animal seed accumulation) and anemochory (via wind)—and seed mass of woody plants across Brazilian ecosystems, testing whether their relative abundance in local plant communities could be predicted by climate, edaphic factors and ...

Molecular Identification of Fusarium Species Associated With Coffee Plantations in Bolivia

open access: yesJournal of Phytopathology, Volume 174, Issue 4, July/August 2026.
ABSTRACT Fungal species associated with coffee and their pathogenic potential remain underexplored in Bolivia. This study aimed to investigate the diversity of Fusarium species associated with coffee in the Amazon basin of Caranavi province in the Yungas region of Bolivia and their ability to induce disease symptoms under controlled conditions. A total

CRISPR/Cas9 Genome Engineering in Non‐Conventional Oleaginous Yeasts: Applications, Challenges, and Prospects

open access: yesYeast, Volume 43, Issue 3, Page 77-88, May 2026.
ABSTRACT Given the biotechnological potential of yeast‐derived oils for oleochemical production, genes encoding lipid metabolism enzymes are key targets for metabolic engineering. Genetic engineering tools such as Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9, Transcription Activator‐Like Effector Nucleases (TALENs), Zinc ...

Biochemical Characterization of a Kunitz‐Type Protease Inhibitor From Mimosa regnellii and Its Effects on Melanoma Cell Viability and Angiogenesis

open access: yesChemistry &Biodiversity, Volume 23, Issue 4, April 2026.
A Kunitz‐type serine protease inhibitor (JTI) purified from Mimosa regnellii seeds selectively targets melanoma cells. JTI triggers mitochondrial apoptosis, increases ROS and Ca2+ levels, arrests the cell cycle, and suppresses migration and angiogenesis without affecting healthy cells.

Synthetic Peptide Inhibition of Trypsin‐Like Proteases in Spodoptera frugiperda (Lepidoptera: Noctuidae): Evaluating the Influence of Gut Microbiota

open access: yesArchives of Insect Biochemistry and Physiology, Volume 121, Issue 3, March 2026.
Synthetic peptides (GORE1 and GORE2) inhibit trypsin‐like proteases in Spodoptera frugiperda, impairing digestion and nutritional performance. Microbiota disruption did not markedly alter enzymatic inhibition but modulated certain developmental responses.

Integrative chromosome‐scale genome analysis of cupuassu provides insights into witches' broom disease resistance and expands genomic resources for Theobroma

open access: yesThe Plant Genome, Volume 19, Issue 1, March 2026.
Abstract Cupuassu (Theobroma grandiflorum) is a fruit tree native to the Brazilian Amazon and increasingly relevant to regional bioeconomies. Its cultivation is severely affected by witches’ broom disease (WBD), caused by Moniliophthora perniciosa. While a chromosome‐scale genome of the susceptible genotype C1074 is available, the lack of a resistant ...
