“…Overall, the M. luci gene expression was highly influenced by 1,4-NTQ treatment with a higher number of DEGs (5,744) than those reported for M. incognita treated with fluensulfone (1,831), fluazaindolizine (3,256), oxamyl (334), and fluopyram (166) ( Wram et al., 2022b ) or in M. incognita treated with P. tenuis huperzine A (1,079) or fungal filtrate (1,635) ( Kassam et al., 2023 ).…”

“…Significant downregulation of all neuropeptidergic genes, with concomitant repression of majority of genes related to chemosensation, esophageal gland secretion, parasitism, fatty acid metabolism, and G-protein-coupled receptors, was identified in fluensulfone-treated M. incognita J2 ( Hada et al., 2021 ). Also, M. incognita transcriptional changes resulting from the exposure to huperzine A, produced by the fungus Paecilomyces tenuis , and to a P. tenuis filtrate were evaluated, unraveling the molecular mechanisms underlying the nematicidal action of these biocompounds, such as downregulation of genes involved in neural response, signaling, and longevity regulating pathways ( Kassam et al., 2023 ). In another study, transcriptome analysis has shown that the nematicidal compound octanoic acid produced by microorganisms such as Bacillus altitudinis and Megasphaera hexanoica can interfere with M. incognita energy metabolism, lifespan, and signaling, with the cuticle, lysosomes, and extracellular regions and spaces being the primary targets by this compound ( Wang et al., 2023 ).…”

Transcriptome analysis reveals the high ribosomal inhibitory action of 1,4-naphthoquinone on Meloidogyne luci infective second-stage juveniles

The root-knot nematode (RKN) Meloidogyne luci presents a threat to the production of several important crops. This nematode species was added to the European Plant Protection Organization Alert list in 2017. The scarce availability of efficient nematicides to control RKN and the phasing out of nematicides from the market have intensified the search for alternatives, such as phytochemicals with bionematicidal properties. The nematicidal activity of 1,4-naphthoquinone (1,4-NTQ) against M. luci has been demonstrated; however, knowledge of the potential mode(s) of action of this compound is still scarce. In this study, the transcriptome profile of M. luci second-stage juveniles (J2), the infective stage, in response to 1,4-NTQ exposure was determined by RNA-seq to identify genes and pathways that might be involved in 1,4-NTQ’s mode(s) of action. Control treatments, consisting of nematodes exposed to Tween® 80 (1,4-NTQ solvent) and to water, were included in the analysis. A large set of differentially expressed genes (DEGs) was found among the three tested conditions, and a high number of downregulated genes were found between 1,4-NTQ treatment and water control, reflecting the inhibitory effect of this compound on M. luci, with a great impact on processes related to translation (ribosome pathway). Several other nematode gene networks and metabolic pathways affected by 1,4-NTQ were also identified, clarifying the possible mode of action of this promising bionematicide.

“…Acremonium , Arthrobotrys , Chaetomium , Monacrosporium , Paecilomyces , Pochonia , Purpureocillium , and Trichoderma are fungi that are antagonistic and trap nematodes with sticky mycelia ( Moliszewska et al., 2022 ). Endophytic fungi like Paecilomyces and Trichoderma can capture and destroy Meloidogyne species in the soil or root systems and restrain their development ( Kassam et al., 2022 ). Similarly, Purpureocillium lilacinum and Pochonia chlamydosporia display the most significant effects and are suitable for biocontrol of M. enterolobii ( Flores Francisco et al., 2021 ).…”

Meloidogyne enterolobii, commonly known as guava root-knot nematode, poses risk due to its widespread distribution and extensive host range. This species is recognized as the most virulent root-knot nematode (RKN) species because it can emerge and breed in plants that have resistance to other tropical RKNs. They cause chlorosis, stunting, and yield reductions in host plants by producing many root galls. It is extremely challenging for farmers to diagnose due to the symptoms’ resemblance to nutritional inadequacies. This pathogen has recently been considered a significant worldwide threat to agricultural production. It is particularly challenging to diagnose a M. enterolobii due to the similarities between this species and other RKN species. Identified using traditional morphological and molecular techniques, which is a crucial first in integrated management. Chemical control, biological control, the adoption of resistant cultivars, and cultural control have all been developed and effectively utilized to combat root-knot nematodes in the past. The object of this study was to get about the geographical distribution, host plants, symptoms, identification, and control techniques of M. enterolobii and recommend future initiatives to progress its management.
