An unusual variant of Meloidogyne arenaria was discovered on roots of a traveler's tree (Ravenala madagascariensis) intended for display at a public arboretum in Pennsylvania. The population aroused curiosity by the lack of visible galling on the roots of the infected plant, and the female vulval region was typically surrounded by egg sacs. Most morphometrics of the population fit within the ranges reported for M. arenaria, with a mosaic of features in common with either M. platani or other…

Using treesbased on Hsp90 genomic alignments, the phylogenetic relationships of these populations and known root-knot nematode species were congruent with previous trees based on ribosomal genes.
First report and morphological and molecular characterization of Meloidogyne incognita from Radermachera sinica in China.
TLDR
The sequences of partial rDNA 18S gene and 28S D2/D3 expansion segment were 99% similar to other M. incognita isolates and three major tropical species, namely M. arenaria, M. javanica, and M. floridensis .
Characterization of a Root-Knot Nematode Population of Meloidogyne arenaria from Tupungato (Mendoza, Argentina).
TLDR
This study represents the first morphometric, morphological, biochemical, reproductive, molecular, and host range characterization of a root-knot nematode species from Argentina and provides data on the identification of root-Knot Nematodes on tomato cultivars from Argentina.
Integrative taxonomy of Meloidogyne paranaensis populations belonging to different esterase phenotypes
TLDR
According to this multi-source approach study, in spite of the intraspecific variation, the phylogenetic position of M. paranaensis is absolute, regardless of the enzymatic phenotype and SCAR markers.
Comparative and Evolutionary Analyses of Meloidogyne spp. Based on Mitochondrial Genome Sequences
TLDR
A molecular taxonomic marker is developed by sequencing a highly-variable ~2 kb mitochondrial region, nad5-cox1, from 36 populations of root-knot nematodes to elucidate relationships within the genus Meloidogyne and present a thorough analysis of the mitochondrial region cox2-rrnS.
Molecular characterization of root-knot nematodes (Meloidogyne spp.) parasitizing potatoes (Solanum tuberosum) in South Africa
TLDR
The high damage potential of resistance-breaking populations of Meloidogyne species is a threat to profitable potato production and will require effective pest management programmes to be put in place.
Identification of Meloidogyne Species from the Central Valley of Chile and Interaction with Stone Fruit Rootstocks.
TLDR
It is illustrated that Prunus rootstocks express different levels of resistance to RKN species, and RKN resistance may be active either at the isolate level, at the species level, or at the genus level.
Meloidoginoses da cultura do tabaco: identificação de espécies, caracterização de isolados e reação de genótipos de Nicotiana spp. a Meloidogyne enterolobii
TLDR
This study defined resistance sources for M. enterolobii thus providing novel information for the literature related to plant nematodes and characterized, based on gall index (GI), the reactions (resistance/susceptibility) of 97 accession of Nicotiana spp.
IDENTIFICATION OF THE PEACH ROOT-KNOT NEMATODE, MELOIDOGYNE FLORIDENSIS,USING mtDNA PCR-RFLP
TLDR
An economical, reliable, and rapid method has been routinely used in the laboratory and allows these two nematode species to be differentiated without sequencing using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP).
