Mechanism Analysis of Rhizosphere Microorganisms Inhibiting Plant Nematodes

In the plant-soil-microbe ecosystem, an imbalance of rhizosphere microorganisms plays an important role in disease development. Some soil-borne pathogens, such as root nematodes, Fusarium glauca, Fusarium acnes, etc., are closely associated with soil microbial imbalances. Around the root system of plants, soil microorganisms, and pathogens interact with each other and affect plant health. Inter-root microecology can achieve nematode suppression through interactions between rhizosphere microorganisms.

Lifeasible, as a leading global company, is committed to helping our customers achieve effective and successful research. We provide a mechanism analysis of plant response to nematodes. In addition, we deliver reliable results and reports on time to our customers worldwide.

Analysis of the Predatory and Parasitic Effects on Nematodes

• The predatory role is mainly for fungi, which can produce set predation and sticky predation due to the different ways of mycelial action. Parasitic microorganisms can come into contact with the root-knot nematodes through spores or directly enter the root-knot nematodes, and the hatching of eggs is inhibited or killed directly.
• Lifeasible provides analysis of the predatory and parasitic effects on nematodes, including action modes of effects and corresponding mechanism analysis.

Analysis of the Induced Root Secretions

• Around the root system of plants, there is an interaction between microorganisms and chemical secretions of the plant root system. Secretions around the plant root system can act on a specific stage of the root-knot nematode life history.

• We provide an analysis of the induction effect on root secretions, including the target of induction, the induction method, and the lethal effect of induction on nematodes.

Analysis of Competitive Effects on Nutrient and Spatial Sites

Rhizosphere microorganisms can occupy signal recognition sites faster and can stably around the root system, making the root-knot nematode less efficient in recognizing the root system of the host plant. We provide an analysis of competitive effects on nutrient and spatial sites, which can reduce plant infection to inhibit disease development.

Analysis of Active Substances to Kill Nematodes

Antagonistic microorganisms are capable of direct penetration of root-knot nematodes and egg walls. We provide analysis of active substances to kill nematodes, including enzymes that produce ablative effects, secondary metabolites with toxic effects, and others.

Analysis of Induction of Resistance in Plant Systems

The rhizosphere microorganisms are capable of producing systemic resistance in plants, and the production of induced systemic resistance (ISR) can be useful against a wide range of common pathogens. We provide analysis of the induction of resistance in plant systems, including resistant enzymes and plant secondary metabolites, and so on.
