Bacterial Bioprotectants: Biocontrol Traits and Induced Resistance to Phytopathogens

Microbiology Research, Journal Year: 2023, Volume and Issue: 14(2), P. 689 - 703

Published: May 22, 2023

Plant growth and nutrition are adversely affected by various factors such as water stress, high temperature, plant pathogens. Plant-associated microbes play a vital role in the development of their hosts under biotic abiotic stresses. The use rhizosphere microbiome for stimulation biological control fungal disease can lead to improved crop productivity. Mechanisms used plant-growth-promoting rhizobacteria (PGPR) protect plants from soilborne pathogens include antibiosis, production lytic enzymes, indole-3 acetic acid production, decreasing ethylene levels secreting 1-aminocyclopropane-1-carboxylate deaminase, competition nutrients niches, parasitism induced systemic resistance. In this review, we emphasize root-associated discuss traits involved pathogen reduction. Future research should focus on effect root exudation plant–pathogen interactions factors. Moreover, microbial fungicides with longer shelf lives will help farmers opt organic agriculture, reducing chemical fertilizers. This trend is expected drive adoption methods agriculture. future prospects diseases bright an increasingly important sustainable

Toward an Efficient Differentiation of Two Diaporthe Strains Through Mass Spectrometry for Fungal Biotyping

Current Issues in Molecular Biology, Journal Year: 2025, Volume and Issue: 47(1), P. 53 - 53

Published: Jan. 15, 2025

Considering that fungi display a great morphological, ecological, metabolic, and phylogenetic diversity, their taxonomic identification is extremely important because it helps us establish information about each species its possible biochemical ecological roles. Traditionally, the of at level has been carried out with molecular tools such as DNA sequencing, but still represents huge challenge today due to heterogeneity fungal kingdom, making task complex difficult process. Biotyping, type chemotaxonomy, developed in field identification/differentiation classification micro-fungi through mass spectrometry (MS). Here, two endophytic strains isolated from different hosts were cultivated studied regarding morphology biology. Morphology analysis determined Diaporthe, results grouped them D. melongenae. We sought faster less way differentiating these interest an MS chemical profile MS/MS data using low-resolution spectrometer. Additionally, we linked this structure compounds previously genus Diaporthe. Studies conducted technique allowed propose distinctive molecules are unique strain share common (13 total). In addition, first report secondary metabolites The dataset demonstrates under investigation can be distinguished via spectrometry, suggesting host affinity; both exhibits pronounced differences profiles across all culture media incubation periods parameters described herein.

Discovery of Sesterdiaporate, an Antifungal Sesterterpene Lactone, against Penicillium italicum, Possibly via Inhibition of Glycosylphosphatidylinositol Biosynthesis from Diaporthe sp. HT-79

Journal of Agricultural and Food Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 2, 2025

The present study reported the discovery of sesterdiaporate (SES), a structurally unique antifungal sesterterpene lactone from Diaporthe sp. HT-79. SES exhibited pronounced inhibitory effect on spore germination and mycelial growth Penicillium italicum, with median effective concentrations (EC50) 0.37 0.079 μg/mL, respectively. This was significantly more than that observed prochloraz (0.74 6.83 respectively). Treatment resulted in swelling both spores mycelia P. italicum as well an increase cell membrane permeability. Further investigation suggested may disrupt glycosylphosphatidylinositol biosynthesis, ultimately leading to death. In vivo tests navel orange fruit showed reducing diameter lesions caused by lesion inhibition percentage 49.4% at concentration 3.7 which superior (14.2% same concentration).

Fungal endophytes from Thalassia testudinum show bioactivity against the seagrass pathogen, Labyrinthula spp.

Frontiers in Marine Science, Journal Year: 2024, Volume and Issue: 11

Published: March 11, 2024

Thalassia testudinum has undergone die-offs in the past century due to seagrass wasting disease caused by Labyrinthula sp. Little is known about how seagrasses resist infections, but metabolites that inhibit were previously extracted from leaves. Furthermore, leaf fungal endophytes possess antipathogenic potential, their activity against unknown. Here, we aimed identify whether of T. can aid defense . Through Illumina amplicon sequencing leaves’ mycobiome, identified fungi are produce antimicrobials. We also isolated and organic compounds test anti- potential using disk diffusion assays. There 22 isolates inhibited , which two isolates, Trichoderma P1a Diaporthe M14, displayed strong inhibition. LC-HRMS/MS analysis determined likely bioactive as peptaibols cytosporone B. Cytosporone B was confirmed via While these organisms low abundance this study demonstrates have play an important role

With the increasing demand for medicinal plants and shortage of resources, improving quality yield making more effective use has become an urgent problem to be solved. In process growth development plants, due threat various adversity, there are problems such as nutrient loss decline. Using traditional chemical pesticides control stress resistance will cause serious pollution environment even endanger human health. Therefore, it is necessary find suitable pesticide substitutes from natural ingredients. As important part microecology endophytes can promote improve hosts, accumulation active components hosts. Because a positive direct impact on host, metabolize rich ingredients, so researchers pay attention it.
