Antibiotics, Год журнала: 2023, Номер 12(1), С. 115 - 115

Опубликована: Янв. 8, 2023

The continuous need to satisfy world food demand has led the search for new alternatives combat economic losses in agriculture caused by phytopathogenic fungi. These organisms cause plant diseases, reducing their productivity and decreasing fruit quality. Among tools being explored is nanotechnology. Nanoparticles with antimicrobial properties could be an excellent alternative address this problem. In work, selenium nanoparticles (SeNPs) were obtained using extracts of Amphipterygium glaucum leaves (SeNPs-AGL) Calendula officinalis flowers (SeNPs-COF). Characterization SeNPs was performed ability as antifungal agents against two commercially relevant pathogenic fungi, Fusarium oxysporum Colletotrichum gloeosporioides, evaluated. Assays different concentrations (0, 0.25, 0.5, 1.0, 1.7 mg/mL). It observed that both had activity pathogens at 0.25 mg/mL above. SeNPs-AGL demonstrated better smaller size (around 8.0 nm) than SeNPs-COF (134.0 nm). FTIR analysis evidenced existence functional groups constitute types SeNPs. There are factors have considered such nanoparticle phytochemical composition used, these may affect bioavailability.

Fusarium species were reported to produce biofilms. Biofilms are superficial societies of microbes bounded and endangered by being situated or taking place outside a cell cells. The most destructive fungal diseases caused phytopathogens as result biofilms formation. wilt banana (Panama disease) is soil-borne pathogen called oxysporum f. sp. cubense. occurs in form complex (FOSC) which encompasses crowd strains. Horizontal genetic factor transfer may donate the observed assortment pathogenic strains, while sexual reproduction unknown FOSC. notorious disease on several crops worldwide. Yield loss this huge, significant destroy crop yields annually, thereby affecting producer countries various continents world. also resistant synthetic chemical fungicides. However, excessive use fungicides during control could be lethal humans, animals, plants. This calls for alternative eco-friendly management targeting formation finally suppressing devastating phytopathogen. In review, we, therefore, described damage disease, concept filamentous biofilms, classical strategies, sustainable strategies using essential oils, prevention vegetables diseases.

The world is facing rapid climate change and a fast-growing global population. It believed that the population will be 9.7 billion in 2050. However, recent agriculture production not enough to feed current of 7.9 people, which causing huge hunger problem. Therefore, feeding 2050 target. Climate becoming threat agricultural production, it expected become worst upcoming years. Keeping this view, very important breed climate-resilient plants. Legumes are considered an pillar system great source high-quality protein, minerals, vitamins. During last two decades, advancements OMICs technology revolutionized plant breeding emerged as crop-saving tool wake change. Various approaches like Next-Generation sequencing (NGS), Transcriptomics, Proteomics, Metabolomics have been used legumes under abiotic stresses. scientific community successfully utilized these platforms investigated Quantitative Trait Loci (QTL), linked markers through genome-wide association studies, developed KASP can helpful for marker-assisted legumes. Gene-editing techniques proven soybean, cowpea, chickpea, model such Medicago truncatula Lotus japonicus . A number efforts made perform gene editing Moreover, did job identifying various genes involved metabolic pathways utilizing resulted information development legume cultivars at pace. review highlights contribution stresses We envisage presented develop cultivars.

Hollow Mesoporous Silica Nanoparticles as a New Nanoscale Resistance Inducer for Fusarium Wilt Control: Size Effects and Mechanism of Action

International Journal of Molecular Sciences, Год журнала: 2024, Номер 25(8), С. 4514 - 4514

Опубликована: Апрель 20, 2024

In agriculture, soil-borne fungal pathogens, especially Fusarium oxysporum strains, are posing a serious threat to efforts achieve global food security. the search for safer agrochemicals, silica nanoparticles (SiO2NPs) have recently been proposed as new tool alleviate pathogen damage including wilt. Hollow mesoporous (HMSNs), unique class of SiO2NPs, widely accepted desirable carriers pesticides. However, their roles in enhancing disease resistance plants and specific mechanism remain unknown. this study, three sizes HMSNs (19, 96, 406 nm HMSNs-19, HMSNs-96, HMSNs-406, respectively) were synthesized characterized determine effects on seed germination, seedling growth, f. sp. phaseoli (FOP) suppression. The exhibited no side cowpea germination growth at concentrations ranging from 100 1500 mg/L. inhibitory FOP mycelial very weak, showing inhibition ratios less than 20% even 2000 Foliar application HMSNs, however, was demonstrated reduce severity roots size- concentration-dependent manner. low concentration mg/L, well HMSNs-19 high 1000 observed little effect alleviating incidence. HMSNs-406 most effective an up 40.00% decline with significant growth-promoting plants. Moreover, foliar (1000 mg/L) increased salicylic acid (SA) content by 4.3-fold, expression levels SA marker genes PR-1 (by 1.97-fold) PR-5 9.38-fold), its receptor gene NPR-1 1.62-fold), compared infected control Meanwhile, another resistance-related PAL also upregulated 8.54-fold. Three defense-responsive enzymes POD, PAL, PPO involved HMSNs-enhanced roots, varying degrees reduction activity. These results provide substantial evidence that exert wilt suppression activating SA-dependent SAR (systemic acquired resistance) responses rather directly suppressing growth. Overall, first time, our indicate role potent inducer serve low-cost, highly efficient, safe sustainable alternative plant protection.

bioRxiv (Cold Spring Harbor Laboratory), Год журнала: 2025, Номер unknown

Опубликована: Янв. 15, 2025

Abstract Endophytic fungi, which live inside plant tissues without causing symptoms of disease, produce a variety bioactive secondary metabolites. These metabolites have applications in biopesticide development, providing eco-friendly alternatives to conventional protection products (PPPs). This study explores the nematicidal and insecticidal properties ethyl acetate (EtOAc) extracts from endophytic fungi isolated wild populations Arabidopsis thaliana central Spain. The effects these against plant-parasitic nematode Meloidogyne javanica , as well two common pest insects ( Myzus persicae Spodoptera littoralis ) were studied. Our results showed that 9 out 13 exhibited significant and/or activity, indicating their potential. Chemical analysis through GC-MS LC-MS revealed active contained great mostly extract-exclusive metabolites, rich chemical diversity was independent activity extract or origin fungal isolate. work highlights importance exploration into produced by endophytes, particularly those model plants like A. . research lays groundwork for future studies aimed at harnessing source products, contributing sustainable agricultural practices improved crop methods.
