Root-knot nematode assessment: species identification, distribution, and new host records in Portugal

Frontiers in Plant Science, 2023
Considered one of the most devastating plant parasitic nematodes worldwide, Meloidogyne spp. (commonly known as the root-knot nematodes (RKNs)) are obligate sedentary endoparasites that establish in the roots, causing hyperplasia and hypertrophy of ...

Meloidogyne javanica Parasitic on Peanut.

Journal of nematology, 2011
Peanut fields in four governorates of Egypt were surveyed to identify species of Meloidogyne present. Fourteen populations obtained from peanut roots were all identified as M. javanica based on perineal patterns, stylet and body lengths of second-stage juveniles, esterase phenotypes, and restriction fragment length polymorphisms of mtDNA.

Biological Products Precondition Field Soil and Induce Changes in Bacterial Communities to Reduce Root‐Knot Nematode Symptoms in Tomato Crops

Plant Pathology, Volume 75, Issue 5, September‐October 2026.
Commercially available biological products, Popul8 (microbial), Eco‐Humate (organic acid) and Eco‐Vital (fish + seaweed) preconditioned field soil and increased the abundance of beneficial bacteria such as Lysobacter, significantly reducing root‐knot nematode symptoms in the greenhouse.

Hostability of maize genotypes to nematodes Pratylenchus brachyurus, Meloidogyne incognita and Meloidogyne javanica [PDF]

, 2019
More than 40 species of nematodes are reported parasitizing maize roots in all cultivation areas and damage caused by some of these phytonematoids can lead to a reduction of 20 - 30% in crop productivity.

Diversity of root-knot nematodes of the genus Meloidogyne Göeldi, 1892 (Nematoda: Meloidogynidae) associated with olive plants and environmental cues regarding their distribution in southern Spain.

PLoS ONE, 2018
Root-knot nematodes of the genus Meloidogyne are recognised worldwide as a major production constraint in crops of primary economic importance. Knowledge of their diversity and prevalence, as well as the major environmental and agronomical cues for ...

The Incorporation of Photosynthates by Meloidogyne javanica.

Journal of nematology, 2011
The root-knot nematode, Meloidogyne javanica, incorporated (1)C from its host after exposure of the plant to (1)CO. This uptake was relatively slow and was not detected in nematodes exposed to a labelled plant for periods of 2 and 4 h, but was after 24 h.

Towards an integrated molecular understanding of plant hormones

Journal of Integrative Plant Biology, Volume 68, Issue 8, Page 2787-2826, August 2026.
This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based

Bioinformatic and functional characterisation of Globodera pallida effector genes [PDF]

, 2012
Pathogens secrete molecules, termed effectors, to manipulate their host to the benefit of the pathogen. Effectors of plant parasitic nematodes are predicted to have a range of functions such as facilitating invasion, initiation and maintenance of the ...

Morphological and molecular characterization of root-knot nematodes from Uzbekistan

Biosystems Diversity
Plant-parasitic nematodes are of great economic importance as widespread harmful plant pests of the world. Among them, root-knot nematodes, especially species of the genus Meloidogyne, cause significant damage to agriculture.

The root‐knot nematode effector Mi1D08B targets a NINJA‐family co‐repressor to suppress jasmonate production and promote infection in soybean

The Plant Journal, Volume 127, Issue 4, August 2026.
SUMMARY Plant‐parasitic nematodes deploy secreted effector proteins that reprogram host cellular processes to establish parasitism. Here, we characterized Mi1D08B, a putative dorsal‐gland effector from the root‐knot nematode Meloidogyne incognita and defined its role in subverting soybean jasmonate‐mediated immunity. Mi1D08B is conserved across several
