Meloidogyne enterolobii is an extremely important plant parasitic nematode. Tomato (Solanum lycopersicum) essential worldwide vegetable, and M. poses a major threat to its production. The present research investigated the effects of different levels inoculum density (100, 500, 1000, 1500, 2000 second-stage juveniles (J2s)/plant) on tomato growth, physiological, biochemical changes at 7, 14, 21, 28 days post-inoculation (dpi). negative impact plants gradually increased when level increased. Therefore, population densities (500–2000 J2s/plant) significantly (p < 0.05) reduced photosynthetic pigmentation, gas exchange, chlorophyll fluorescence compared control plants, while low (100 showed very little influence. Furthermore, with highest (2000 exhibited greater number egg masses galls. notable correlation significant elevation both malondialdehyde (MDA) hydrogen peroxide (H2O2) levels, which are recognized as detrimental stresses in plants. Similarly, rise activity several defensive antioxidant enzymes, namely superoxide dismutase (SOD), catalase (CAT), peroxidase (POD), indicates mechanism used combat oxidative destruction produced by enterolobii. specific glutathione (GSH) ascorbate (ASA) potent defense molecules response induced damage. In addition, our findings also demonstrated that secondary metabolites responsible for scavenging stress However, further required explore underlying reasons this phenomenon develop efficient chemical or biocontrol strategies managing

Application Potential of Bacterial Volatile Organic Compounds in the Control of Root-Knot Nematodes

Molecules, Год журнала: 2022, Номер 27(14), С. 4355 - 4355

Опубликована: Июль 7, 2022

Plant-parasitic nematodes (PPNs) constitute the most damaging group of plant pathogens. Plant infections by root-knot (RKNs) alone could cause approximately 5% global crop loss. Conventionally, chemical-based methods are used to control PPNs at expense environment and human health. Accordingly, development eco-friendly safer has been urged supplement or replace for RKNs. Using microorganisms their metabolites as biological agents (BCAs) is a promising approach controlling Among metabolites, volatile organic compounds (VOCs) have gained increasing attention because potential in not only RKNs but also other pathogens, such insects, fungi, bacteria. This review discusses biology well status various strategies. The discovery VOCs emitted bacteria from environmental sources application BCAs specifically addressed.

Mechanisms of plant cell wall surveillance in response to pathogens, cell wall-derived ligands and the effect of expansins to infection resistance or susceptibility

Frontiers in Plant Science, Год журнала: 2022, Номер 13

Опубликована: Авг. 23, 2022

Cell wall integrity is tightly regulated and maintained given that non-physiological modification of cell walls could render plants vulnerable to biotic and/or abiotic stresses. Expansins are plant wall-modifying proteins active during many developmental physiological processes, but they can also be produced by bacteria fungi interaction with hosts. alteration brought about ectopic expression, overexpression, or exogenous addition expansins from either eukaryote prokaryote origin in some instances provide resistance pathogens, while other cases become more susceptible infection. In these circumstances altered mechanical properties might directly responsible for pathogen susceptibility outcomes. Simultaneously, through membrane receptors enzymatically released fragments sensing modified barrier properties, trigger intracellular signaling cascades inducing defense responses reinforcement the wall, contributing various infection phenotypes, which involved. Here, we review immune response activated surveillance mechanisms, identified as responses, expansin's roles attack.

Counter-attack of biocontrol agents: Environmentally benign Approaches against Root-knot nematodes (Meloidogyne spp.) on Agricultural crops

Heliyon, Год журнала: 2023, Номер 9(11), С. e21653 - e21653

Опубликована: Окт. 28, 2023

Root-knot nematodes (Meloidogyne spp.) are obligate sedentary endoparasites, considered severe crop-damaging taxa among all plant-parasitic globally. Their attacks through parasitic proteins alter the physiology and machinery of host cells to favour parasitism reduction in crop yield. Currently, use excessive pesticides as a fast remedy manage this pest is hazardous for both environment humans. Keeping view mind, there an urgent need developing efficient eco-friendly strategies. Bio-control best approach without disturbing non-target microbes. In bio-control, living agents such fungi bacteria natural enemies substitute pesticides. Fungi, including nematode-trapping fungi, can sense signals produce special trapping devices viz., constricting rings adhesive knobs/loops, capture kill them. Whereas, endo-parasitic by enzymatic secretions spore adhesion their hyphae. Bacteria also control producing antibiotic compounds, competing nutrients rhizosphere, production hydrolytic enzymes chitinases, proteases, lipases, induction systemic resistance (ISR) plants. Scientists throughout world trying evolve environmentally benign methods that sustain agricultural keep below threshold level. Whatever evolve, future focus should be on important aspects like green approaches managing human health environment.

Vermicomposting of Pleurotus eryngii spent mushroom substrates and the possible mechanisms of vermicompost suppressing nematode disease caused by Meloidogyne incognita

Heliyon, Год журнала: 2023, Номер 9(4), С. e15111 - e15111

The mushroom industry produces a large amount of spent substrate (SMS), which requires geographical footprint and causes pollution. Vermicomposting is low-cost technology for its value in recycling organic wastes production beneficial fertilizers. In this study, the changes physicochemical properties was characterized during vermicomposting Pleurotus eryngii SMS with cow dung (CD) as amendment. efficiency possible mechanisms vermicompost suppressing disease induced by Meloidogyne incognita also investigated. Six combinations different ratios included using Eisenia fetida. Effect against M. on tobacco conducted under greenhouse condition. And investigated evaluated species diversity nematode-trapping fungi (NTF) soil, defense response enzymes tobacco. combination 65% +35% CD more suitable vermicomposting, highest (57%) earthworm biomass increment (268%) were achieved. Additionally, reduction pH, total carbon, carbon: nitrogen ratio, pronounced elevation four overall nutrient status observed. Soil amended (100:1 w/w) showed 61% control nematode caused tobacco, significantly higher than that normal compost (24%).

The holobiont concept has revolutionized our understanding of plant-associated microbiomes and their significance for the development, fitness, growth resilience host plants. olive tree holds an iconic status within Mediterranean Basin. Innovative changes introduced in cropping systems, driven by increasing demand its derived products, are not only modifying traditional landscape this relevant commodity but may also imply that either or emerging stresses can affect it ways yet to be thoroughly investigated. Incomplete information is currently available about impact abiotic biotic pressures on holobiont, what includes specific features associated microbiome relation host’s structural, chemical, genetic physiological traits. This comprehensive review consolidates existing knowledge stress factors affecting cultivation compiles microbiota with different tissues organs. We aim offer, based evidence, insightful perspective diverse stressing disturb structure, composition network interactions olive-associated microbial communities, underscoring importance adopt a more holistic methodology. identification gaps emphasizes need multilevel research approaches consider conceptual framework future investigations. By doing so, powerful tools promote olive’s health, productivity envisaged. These assist designing sustainable agronomic practices novel breeding strategies effectively face evolving environmental challenges growing high quality food products.

Root-knot nematodes especially Meloidogyne spp. are considered as most destructive obligate parasites that substantially reduce crop yield and quality. Fosthiazate is an efficient organothiophosphate chemical with nematicidal activity against The present study aimed to analyze the efficacy of fosthiazate root-knot disease in Cucumis melo var. saccharinus its potential effects on rhizosphere microbiome metabolites. (40%) was applied two times by spraying day transplanting during pollination period (after 31 days). Samples from treatment (fosthiazate 40%: MF) control groups (untreated plants; MCK) were analysed through metagenomic metabolomic profiling rhizospheres.
