Meloidogyne enterolobii risk to agriculture, its present status and future prospective for management

Abstract

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.

Meloidogyne enterolobiiMeMSP1 effector targets the glutathione‐S‐transferase phi GSTF family in Arabidopsis to manipulate host metabolism and promote nematode parasitism

“…are obligate plant parasites with a world‐wide distribution; they are considered the most devastating of plant‐parasitic nematodes (Jones et al ., 2013). Meloidogyne enterolobii is an emerging RKN species capable of overcoming most of the nematode resistance genes in crops (Sikandar et al ., 2022). One of the specific features of RKN interactions with plants is their ability to reprogram root cells to form specialised giant, hypertrophied, and multinucleate‐feeding cells, which serve as their sole source of nutrients (Favery et al ., 2020).…”

“…The root-knot nematode, Meloidogyne enterolobii, is an emerging phytopathogen that presents a signi cant threat owing to its rapid geographical spread, wide range of susceptible host species, and the capacity to infect crops resistant to other nematode species of the same genus (Sikandar et al, 2023). Red tomato (Solanum lycopersicum) is one of the most important crops in Mexico, and its production is affected by M. enterolobii.…”
