Abstract Four species of plant parasitic nematodes were present in soil samples planted with forage legumes at Alachua County, Florida, USA. The detected species Belonolaimus longicaudatus, Criconemella ornate, Hoplolaimus galeatus, and Paratrichodorus minor were described in the present study. They belong to orders Rhabditida (Belonolaimus longicaudatus, Criconemella ornate, and Hoplolaimus galeatus) and Triplonchida (Paratrichodorus minor) and to taxonomical families Dolichodoridae (Belonolaimus longicaudatus), Hoplolaimidae (Hoplolaimus galeatus) Criconematidae (Criconemella ornate), and Trichodoridae (Paratrichodorus minor). The identification of the present specimens was based on the classical taxonomy, following morphological and morphometrical characters in the species specific identification keys.

  • Sting Nematodes Modify Metabolomic Profiles of Host Plants
    www.nature.com/scientificreports OPEN Sting nematodes modify metabolomic profles of host plants Denis S. Willett1,5*, Camila C. Filgueiras1,5, Nicole D. Benda2, Jing Zhang3 & Kevin E. Kenworthy4 Plant-parasitic nematodes are devastating pathogens of many important agricultural crops. They have been successful in large part due to their ability to modify host plant metabolomes to their beneft. Both root-knot and cyst nematodes are endoparasites that have co-evolved to modify host plants to create sophisticated feeding cells and suppress plant defenses. In contrast, the ability of migratory ectoparasitic nematodes to modify host plants is unknown. Based on global metabolomic profling of sting nematodes in African bermudagrass, ectoparasites can modify the global metabolome of host plants. Specifcally, sting nematodes suppress amino acids in susceptible cultivars. Upregulation of compounds linked to plant defense have negative impacts on sting nematode population densities. Pipecolic acid, linked to systemic acquired resistance induction, seems to play a large role in protecting tolerant cultivars from sting nematode feeding and could be targeted in breeding programs. Nematodes are ubiquitous denizens of belowground environments. While many are free-living, the more than 4000 plant-parasitic nematodes are devastating in their impacts on human agriculture1,2. Most important agri- cultural crops sufer yield suppression from plant-parasitic nematodes with annual economic damage estimates exceeding $100 billion1,3. This devastation is due in part to the success of plant-parasitic nematodes as pathogens in overcoming plant defenses. Indeed, the manner in which plant-parasitic nematodes overcome plant defenses makes them a model system for understanding basic plant biology and mechanisms of resistance3,4.

  • Variation Among Populations of Belonolaimus Iongicaudatus I
    Variation among Populations of Belonolaimus Iongicaudatus I R. T. ROBBINS and HEDWIG HIRSCHMANN 2 Abstract: Three North Carolina populations of Belonolairnus longicaudatus differed significantly from three Georgia populations in stylet measurements, the c ratio, the distance of the excretory pore from the anterior end for both sexes; the a ratio for females only; and the total body length, tail length, and spicule length for males only. The Georgia nematodes were stouter, and the females possessed sclerotized vaginal pieces. The distal portion of the spicules of North Carolina males had an indentation and hump lacking in those of the Georgia males. The haploid number of chromosomes was eight for males from all populations of B. longicaudatus and a North Carolina population of B. rnaritimus. Interpopulation matings of the Tarboro, N.C. and Tifton, Ga. populations indicated that the offspring produced were infertile. Morphological differences and reproductive isolation suggest that the North Carolina and the Georgia populations belong to different species.

POWERS3 Abstract: Belonolaimus isolates from six U.S. states were compared by restriction endonuclease diges- tion of amplified first internal transcribed spacer region (ITS1) of the nuclear ribosomal genes. Seven restriction enzymes were selected for evaluation based on restriction sites inferred from the nucleotide sequence of a South Carolina Belonolaimus isolate. Amplified product size from individuals of each isolate was approximately 700 bp. All Midwestern isolates gave distinct restriction digestion patterns. Isolates identified morphologically as Belonolaimus longicaudatus from Florida, South Carolina, and Palm Springs, California, were identical for ITS1 restriction patterns.

  • Numerical Taxonomy Helps Identification of Merliniidae
    Journal of Nematology 49(2):207–222. 2017. Ó The Society of Nematologists 2017. Numerical Taxonomy Helps Identification of Merliniidae and Telotylenchidae (Nematoda: Tylenchoidea) from Iran REZA GHADERI,HABIBALLAH HAMZEHZARGHANI, AND AKBAR KAREGAR Abstract: Numerical taxonomy was used for identification and grouping of the genera, species, and populations in the families Merliniidae and Telotylenchidae. The variability of each of 44 morphometric characters was evaluated by calculation of the co- efficient of variability (CV) and the ratio of extremes (max/min) in the range of 1,020 measured females. Also correlation and regression analyses were made between characters to find potential collinearities. Hierarchical cluster analysis (HCA) was used for (i) grouping 21 genera in the superfamily Dolichodoroidea based on literature data coded for states of 18 diagnostic characters, and (ii) for grouping Iranian populations belonging to selected genera. Furthermore, STEPDISC analysis was used for (i) grouping 11 genera of Merliniidae and Telotylenchidae based on the measurements of 35 characters from 1,007 Iranian female specimens, and (ii) grouping measured females of eight species of Amplimerlinius and Pratylenchoides. The multivariate data analysis approach showed robust enough to summarize relationship between morphometric characters and group genera, species, and populations of the nematodes and in particular help to identify the genera and species of Amplimerlinius and Pratylenchoides.

Received: 18 September 2019; Accepted: 30 October 2019; Published: 2 November 2019 Abstract: MicroRNAs (miRNAs) are an extensive class of small regulatory RNAs. Knowing the specific expression and functions of miRNAs during root-knot nematode (RKN) (Meloidogyne incognita) development could provide fundamental information about RKN development as well as a means to design new strategies to control RKN infection, a major problem of many important crops. Employing high throughput deep sequencing, we identified a total of 45 conserved and novel miRNAs from two developmental stages of RKN, eggs and J2 juveniles, during their infection of cotton (Gossypium hirsutum L.). Twenty-one of the miRNAs were differentially expressed between the two stages. Compared with their expression in eggs, two miRNAs were upregulated (miR252 and miRN19), whereas 19 miRNAs were downregulated in J2 juveniles.

  • Amended Descriptions of Belonolaimus Gracilis Steiner, 1949 and B
    198 PROCEEDINGS OF THE [VOL. 28, No. 2 Amended Descriptions of Belonolaimus gracilis Steiner, 1949 and B. longicaudatus Ran, 1958 (Nematoda: Tylenchida) * GEORGE J. RAU** The genus Belonolaimus was established with B. gracilis as the only species (Steiner, 1949). All populations of the genus were usually referred to this species until 1958, when Rau, on the basis of extensive collections, described B. longicaudatus and expressed the opinion that this species, not B. gracilis, is the common sting nematode in the southeastern United States. This opin- ion was based on the fact that collections made in the vicinity of Ocala, the type location for B. gracilis, and in many other parts of Florida did not contain nematodes corresponding to the description of this species. Since 1958, many additional collections of Belonolaimus longicaudatus have been made, and sting nematodes corresponding in most details to the description of B. gracilis have been found around the roots of long leaf pine (Pinus palustris Mill.) in the Ocala National Forest near Ocala, Florida. This is the reported type location, and the nematodes were successfully transferred to the reported type host, slash pine (Pinus elliottii Engelm. (P. caribaea Morelet)), growing only on Lakewood sand, in the greenhouse. Steiner also reported long leaf pine as a host of B. gracilis. The purposes of this paper are to amend the original description of B. gracilis, record variation in this species, amend the description of B. longi- caudatns by correction of some of the dimensions originally given, and pre- sent additional information on another collection from the type location.
