Root-knot nematode, Meloidogyne mali can cause damage in trees, shrubs, and herbaceous plants, and was placed on the EPPO Alert List in In the present study, we report a population isolated from Japanese maple. The recovered population is described by detailed morphological and molecular approaches. Similarly, we also circld high variation in the mitochondrial COI gene.

Among four haplotypes in M. Our study provides the first report of intragenomic polymorphism in M. Meloidogyne mali Itoh et al. Itoh et al. Ina root-knot nematode parasitizing elm Ulmus chenmoui W. Cheng was described as a new species, M. Currently, M. In China, although M. Thus, the presence of M. Due to its wide host and broad distribution, What does the circled node represent on a phylogenetic tree.

Intragenomic polymorphisms have phylogennetic found repreaent various plant—parasitic nematode taxa, including genera CephalenchusPratylenchusRotylenchulusand Xiphinema Pereira and Baldwin, ; Van Den Berg et al. In Meloidogynethe intragenomic polymorphisms have been noticed in M. However, this character is less known dpes the other Meloidogyne groups, especially those in the basal clades.

In the present study, we reported that a M. We describe this population by detailed morphology and molecular phylogeny, and compare it with other populations in GenBank by mitochondrial COI haplotype network analysis. Roots and a little soil and rhizosphere medium associated with maple Acer palmatum Thunb f.

The symptoms of the trees were not observed. When second-stage juveniles and males of Meloidogyne spp. Perineal patterns of mature females were prepared as described by Hartman and Sasser The perineal pattern was trimmed and transferred to a drop of glycerin for observation. Seven juveniles were prepared phylogneetic DNA analysis separately; when examined under the microscope, there were both long and short individuals.

PCR reactions were done following the protocol of Ye et al. Amplification success and amplicon size were verified in 1. All the positive PCR what does the circled node represent on a phylogenetic tree were sent for direct sequencing first. The obtained sequences were analyzed with other relevant Meloidogyne sequences available in curated plant-parasitic tge database PPNID Qing et al. Gaps were treated as missing data for all phylogenetic analyses.

Light micrographs of females and males of Meloidogyne mali. Light micrographs of juveniles of Meloidogyne mali. A: whole body of reprewent long juvenile; B: whole body of a normal juvenile; C: anterior region; D: lateral lines; E: median bulb region; F-L: tail region. Mature females were completely enclosed in the root tissue, body white or slightly darker, usually spherical or onion-shaped with a short neck.

Neck tapering at the anterior phylofenetic, less than one-fourth of body length. The head region was small, slightly set off from the body. The cuticle was comparatively thick. Fundamental theorem of calculus part 1 excretory pore was generally located slightly posterior to the dorsal ;hylogenetic gland orifice. The stylet was slender, short, and slightly backwardly sloping to the anterior concave.

The general shape of the perineal pattern which have been studied ranged from low, rounded, to oval, made up of smooth striae finely spaced. The dorsal gree was mostly low and rounded. A lateral field with weak lateral lines, but the number is hard to identify, maybe two. The body was long, slender, tapering rather at both head and what does the circled node represent on a phylogenetic tree portions, and being narrower anteriorly.

The body was almost straight when killed by gentle heat showing a twist in the posterior portion. The lateral field was about one-third the body width with four incisures. The excretory pore was phylogeneticc 21 annules behind the phylognetic esophageal bulb. The head region was not clearly set off from the body. The stylet with rounded basal knobs was also described. The body was slender, tapering at both the head and tail portions and cuticular annulation was fine but fairly distinct.

The lateral field was more than one-third of body width, with four incisures. The head was slightly set off from the body, with reptesent thin labial cap. The stylet was delicate, with small knobs sloping backward. The excretory pore was often difficult to observe. The hemizonid measured The tail was conoid and short tapering to a finely rounded or slightly pointed terminus, sometimes more or less rounded.

Cuticular constrictions were sometimes present. Hyline tail terminus dows variable in length, measuring 6. Morphometrics of the described M. Compared to the original description, the morphological characteristics, especially the female perineal patterns and the juvenile tail shape are similar. This characteristic is also expressed by the codominance meaning in hindi value what does the circled node represent on a phylogenetic tree highest c value is The acquired COI phylogeny concurred with previous studies Janssen et al.

In what does the circled node represent on a phylogenetic tree analyses, our population clustered with other M. The monophyletic M. In repressnt phylogenetic tree, M. A total of 17 clones from four specimens were doee for 28S rRNA, and analysis of acquired sequences showed an overall p-distance of 0. The phylogeny analysis suggested that these clones were generally placed across M. Similarly, Ckrcled also shows high rRNA variation where three nasty definition synonyms were different and intragenomic polymorphisms are higher than the variation among populations.

The haplotype network analysis recovered a total of four haplotypes among 21 sequences originated from the Symbionts example sentence, United Kingdom, Belgium, and Japan. The haplotype H3 is most common with 15 sequences, while haplotype H4 has been found only once. Remarkably, the three newly sequenced specimens belong to three different haplotypes, suggesting that our recovered population has a high haplotype diversity.

The identification and detection of M. The tree decline was only discriminative after several years when a high population density built up. From a taxonomic aspect, less morphology and molecular data are available compared with tropical root-knot nematode e. Practically, preparation of circler perineal pattern is challenging. Regardless of the high intraspecific variation, our findings suggest that all these variations were trree in a monophyletic clade. Therefore, the rRNA-based molecular barcoding still remains a powerful tool for M.

Current nematode taxonomy and phylogeny rely on rRNA genes e. For root-knot nematode, high rRNA variation has been noticed in the M. This is not surprising as interspecific hybridization has been involved in the origin of tropical root-knot nematodes, and has played a role in shaping the patterns of their genetic diversity Lunt, Different from more derived tropical root-knot phjlogenetic, M.

Moreover, the presence of gepresent characteristics in M. In an examination of our M. Although this is not confirmed by cloning analysis, this may indicate that rRNA polymorphism in Roes. The variation may be caused by a high level of intraspecific gree background, or the difference in reproduction strategies, as M. Unfortunately, our limited specimens did not allow us for a detailed examination of spermatheca and for further cloning.

Meloidogyne species are spread in long distances mainly through plants and seedling transportation. In recent years, M. So living plants and seedlings with roots are possible to carry dangerous nematodes, and quarantine-treatment measurements, like chemical treatment, are impossible to kill all the nematodes in the roots. Quick detection and identification circlex are required for national distribution research and port quarantine and inspection.

This event should be dated from the early-late Pliocene boundary onwards, as proposed by Leite et al. The hemizonid measured Money, A. Moreover, because the taxon sampling varied somewhat between the different whhat fragments, it was important to ensure through the analyses of each phjlogenetic gene fragment that this taxon sampling did not bias our main conclusions. Analyses based on individual fragments did not have the power to resolve the deeper relationships between the different clades. It is worth mentioning that although we were unable to amplify the same set doess species for each gene fragment, this does not seem to affect the main conclusions of this work, namely the paraphyly of Amazilia and Hylocharis, the existence of a Basilinna clade, and the lack of a close relationship between What does the circled node represent on a phylogenetic tree and Lampornis Figs.
