“…For example, the commercialized Streptomyces lydicus WYEC108 strain, as a root-colonizing actinomycete has five properties that either suppress fungal pathogens or enhance plant growth: (1) rhizosphere competent; (2) antibiosis; (3) mycoparasitism; (4) cellulose and chitinase production; and (5) siderophore production [40]. Moreover, Streptomyces galilaeus strain KPS-C004 suppressed up to 58% of root-knot disease of chili caused by Meloidogyne incognita in a greenhouse experiment, promoted plant growth by increasing biomass and plant nutrients; and did not affect soil bacterial community [16]. Likewise, S. hydrogenans strain DH16 and its metabolites were proven to be safe nematicides against M. incognita and were characterized by plant growth-promoting properties [41].…”

“…It has been recently shown that Streptomyces galilaeus strain KPS-C004 suppressed M. incognita and promoted plant growth by increasing plant biomass, shoot, and root length in chili host plants [15]. Similarly, Streptomyces antibioticus strain M7 culture supernatant/cells/solvent extracts caused increased mortality of M. incognita and promoted growth in tomato plants [16]. Similarly, biocontrol experimentation was also conducted for M. javanica control [17].…”

A total of 461 indigenous Streptomycetes strains recovered from various Greek rhizosphere habitats were tested for their bioactivity. All isolates were examined for their ability to suppress the growth of 12 specific target microorganisms. Twenty-six were found to exert antimicrobial activity and were screened for potential nematicidal action. S. monomycini ATHUBA 220, S. colombiensis ATHUBA 438, S. colombiensis ATHUBA 431, and S. youssoufensis ATHUBA 546 were proved to have a nematicidal effect and thus were further sequenced. Batch culture supernatants and solvent extracts were assessed for paralysis on Meloidogyne javanica and Meloidogyne incognita second-stage juveniles (J2). The solvent extracts of S. monomycini ATHUBA 220 and S. colombiensis ATHUBA 438 had the highest paralysis rates, so these Streptomycetes strains were further on tested for nematodes’ biological cycle arrest on two Arabidopsis thaliana plants; the wild type (Col-0) and the katanin mutant fra2, which is susceptible to M. incognita. Interestingly, S. monomycini ATHUBA 220 and S. colombiensis ATHUBA 438 were able to negatively affect the M. incognita biological cycle in Col-0 and fra2 respectively, and increased growth in Col-0 upon M. incognita infection. However, they were ineffective against M. javanica. Fra2 plants were also proved susceptible to M. javanica infestation, with a reduced growth upon treatments with the Streptomyces strains. The nematicidal action and the plant-growth modulating abilities of the selected Streptomycetes strains are discussed.

“…RKN is one of the most economically damaging plant pathogens and causes stunted growth, resulting in quality and yield of in different crop species (Borah et al 2018;Akram et al 2019;Singh et al 2019). In the present study, RKN infestation could signi cantly decrease the belowground biomass of P. notoginseng seedings, especially large-sized and medium-sized ones, and resulted in a lower root/shoot ratio of P. notoginseng (Table 2).…”

Root-knot nematode (RKN) is a soil-borne pathogen that severely damages Panax notoginseng. It has been recently shown that intercropping P. notoginseng in forests constitutes an innovative system that can promote P. notoginseng growth and suppress the spread of disease. However, there is little research on the interspeci c interaction between pine trees and P. notoginseng. Here, two years of eld experiments were designed to explore the effects of RKN infestation and P. notoginseng-pine tree intercropping on the growth and saponin synthesis of P. notoginseng. The results showed that RKN infestation could signi cantly reduce the root biomass, nutrient uptake and saponin accumulation of P. notoginseng seedlings. Interestingly, two-year-old P. notoginseng plants grew normally (speci cally, root biomass, saponin synthesis, nutrient uptake and root morphology were normal) under nematode infection, while the incidence of RKN disease was decreased compared with that of seedlings before transplantation, indicating that P. notoginseng has adult-plant resistance (APR) to RKN disease. Furthermore, P. notoginseng-pine tree intercropping could signi cantly reduce the incidence of RKN disease and increase the biomass, nutrient uptake and saponin synthesis of P. notoginseng under mild infection, and root architecture may play a key role. Above all, P. notoginseng showed APR to RKN disease, and P. notoginseng-pine tree intercropping represents a type of interspeci c facilitation that can promote the growth and quality of P. notoginseng.

“…They are also known to attack diverse portions of vascular plants, with the majority feeding on or in plant roots and the minority feeding on aerial parts [4]. PPNs are major threats to the world's food supply, accounting for at least 12.3% of global food production loss each year [5]. One of the most significant worms associated with PPNs is the root-knot nematode (Meloidogyne sp.).…”

Root-knot nematodes are among the most significant pathogenic organisms due to their global distribution, capacity for destruction, and economic importance. Antagonistic bioagents are more effective alternative to synthetic pesticides in the suppression of root-knot nematodes. Bioagents reduce the use of synthetic chemicals, which are hazardous to both humans and the environment. Despite this, some bioagents, such as fungi and bacteria have unknown mechanisms. This review discusses the nematophagous bacteria and fungi that have been discovered so far, including Pochonia, Trichoderma sp., Pseudomonas sp., and Bacillus sp., with an overview of the current advances in research regarding their molecular and biochemical control mechanisms. Biological control agents (BCAs), as valuable ecological enemies of nematode infestations, use a range of mechanisms, such as parasitism, nutrient competition, toxin production, induce systemic resistance to antibiotics, enzymes, and enhance plant health. They suppress nematodes directly, improve plant growth, and facilitate the colonization and activities of antagonistic microbes in the rhizosphere. Understanding the molecular basis of BCAs suppression mechanisms provides the basis for their future incorporation into phytopathogen or plant disease control management. This study reviews the current threat posed by the root-knot nematode, biological control, antagonistic bioagents, and their mechanisms, and the future perspectives in modern agricultural sustainability to provide basis for the broad control of root-knot nematodes.
