Control of Plant Nematodes by Endophytic Bacteria

All microorganisms that inhabit, at least for one period of their life cycle, the interior of a plant may be considered an endophyte. The endophytes, epiphytes (those that live on the surface of plants), and phytopathogens (those that cause diseases in plants), differ gradually from each other, and it is difficult to draw sharp limits to discriminate each category. Endophytic bacteria have been found internally in root tissue, where they persist in most plant species. They have the capability of colonizing internal host tissues, and this makes them a valuable tool for improving crop performance. By systemically colonizing roots, they have the potential to develop into biological control agents of plant parasitic nematodes.

Lifeasible provides services to customers worldwide in the field of control of plant nematodes by endophytic bacteria. Our platform is equipped with advanced facilities and professional experts to support related research. Here we provide various services according to customer needs.

Analysis of the Bacillus Strains

• The use of endophytic bacteria to manage plant-parasitic nematodes is a relatively new approach. Endophytes colonize the same root tissues as sedentary plant-parasitic nematodes. Therefore, this association of endophytic bacteria with nematodes throughout the nematode life cycle makes these bacteria excellent candidates for biocontrol strategies.
• In recent years, scientists have isolated many endophytic bacteria from plant tissues that can both promote plant growth and control plant parasitic nematode diseases.

• Lifeasible provides analysis services for plant endophytic bacteria such as Bacillus amyloliquefaciens, B. cereus, B. subtilis, B. megaterium, etc., and analyzes their inhibition and revival rates against nematodes.
• We also provide mechanism analysis services for the control of plant nematodes by endophytic bacteria, such as direct antagonism using metabolites and induced systemic resistance.
• In addition, we help analyze the bioactivity, acid-base stability, protease stability, and high temperature stability of fermentation broths based on endophytic bacteria from plants.

Analysis of the Other Strains

• It is reported that there are many bacteria in plants that can produce nematocidal active substances, and some of them produce nematocidal substances that are highly stable and have great potential for exploitation.
• We offer analysis of other strains, including Panagrellus redivivus, Mesorhizobium tamadayense, Enterobacter ludwigii, Serratia marcescens, Pseudomonas aeruginosa, P. fluorescens and others.
