Potential of Three Plant Extracts in Suppressing Potato Dry Rot Caused by Fusarium incarnatum Under Normal and Cold Storage

Agronomy, Journal Year: 2025, Volume and Issue: 15(3), P. 593 - 593

The potato (Solanum tuberosum L.) is one of the most widely consumed vegetable crops worldwide. During storage, tubers are vulnerable to various phytopathogenic fungi. Dry rot, caused by Fusarium incarnatum, a common and serious disease that affects tubers, leading partial or complete decay during storage. current study assessed effectiveness three ethanolic extracts including cinnamon bark (CIB), clove buds (CLB), avocado seeds (AVS) in controlling dry rot under both normal cold storage conditions. In vitro bioassay demonstrated all tested exhibited dose-dependent fungistatic effect against F. with inhibition percentages 83.33% for CIB, 72.22% CLB, 67.77% AVS at highest concentration. Moreover, dipping markedly reduced severity Additionally, treated showed increased activities defense-related enzymes, catalase, peroxidase, polyphenol oxidase, phenylalanine ammonia-lyase. Furthermore, there were higher levels total soluble phenolics flavonoids, along an increase lignin content reduction weight loss stored compared control group. mitigated infection stress lowered malondialdehyde tubers. These show potential as environmentally friendly alternatives chemical fungicides managing incarnatum

Unlocking Nature’s Microbial Defenders: Genetic Mechanisms and Potential Against Monilinia spp. Pathogens

Microorganisms, Journal Year: 2025, Volume and Issue: 13(4), P. 818 - 818

Published: April 3, 2025

Monilinia spp., which causes brown rot, is one of the most damaging pathogens in stone fruits. Researchers are exploring epiphytic and endophytic microorganisms with potential to suppress pathogens, control pathogenic microorganisms, and/or promote plant growth. In this study, antagonistic activity against three species were isolated from plum orchard soil Antagonism tests vitro showed strong properties six strains bacteria two yeast-like fungi M. fructigena, fructicola, laxa, growth inhibition 45.5 84.6%. The antagonists identified characterized at genetic level using whole genome sequencing (WGS). Genes involved antibiotic resistance, virulence, secondary metabolite synthesis, promotion through mapping, gene prediction, annotation. None studied predicted be humans. results study indicate that Bacillus pumilus, B. velezensis, Lysinibacillus agricola, Pseudomonas chlororaphis fruit soil, fungus Aureobasidium pullulans, plums, promising candidates for biological spp.

The Dual Pathogen Fusarium: Diseases, Incidence, Azole Resistance, and Biofilms

Journal of Fungi, Journal Year: 2025, Volume and Issue: 11(4), P. 294 - 294

Published: April 9, 2025

The increasing resistance of Fusarium species to nearly all first-line antifungal agents in clinical settings has led its designation as a 'high-priority' human pathogen. As dual pathogen, spp. threaten both health and crop production, impacting food security. Our recent drug profiling isolates reveals several front-line antifungals, with notable cross-azole observed plant-associated strains. While the overuse agricultural azoles been implicated selection azole-resistant fungi such Aspergillus, similar mechanism assumed for settings. However, direct genetic evidence supporting this hypothesis remains limited. In review, part our Special Interest (SI) series, we discuss spectrum diseases caused by Fusarium. incidence data are better established keratitis onychomycosis, invasive fusariosis globally underreported. We propose reasons distinct bias explore potential basis azole resistance.
