Use of the Arbuscular Mycorrhizal Fungus Glomus Intraradices As Biological Control Agent of the Nematode Nacobbus Aberrans Parasitizing Tomato

Some populations of this nematode show preference for certain hosts, revealing the existence of “races/groups” with different behaviour and making nematode management difficult. A possible biological control alternative to reduce the damage caused by this species may be the use of arbuscular mycorrhizal fungi (AMF). In the present work, the effect of Glomus intraradices on tomato plants inoculated with the nematode at transplanting and three weeks later was tested. At 60 days, the following parameters were estimated: percentage of AMF colonization, root and aerial dry weight, number of galls and egg masses, and reproduction factor (RF=final population/initial population) of N. aberrans . AMF colonization was higher in the presence of the nematode. -

Phylum-wide nematode phylogenetic hypotheses have mainly been based on nuclear rDNA sequences, but more recently complete mitochondrial (mtDNA) gene sequences have provided another source of molecular information to evaluate relationships. Although there is much agreement between nuclear rDNA and mtDNA phylogenies, relationships among certain major clades are different. In this study we report that mtDNA sequences do not support the monophyly of Ascaridida, Oxyurida and Spirurida (clade III) in contrast to results for nuclear rDNA. Results from mtDNA genomes show promise as an additional independently evolving genome for developing phylogenetic hypotheses for nematodes, although substantially increased taxon sampling is needed for enhanced comparative value with nuclear rDNA. -
Nematodes and Agriculture in Continental Argentina

DOUCET and Marîa M.A. DE DOUCET Laboratorio de Nematologia, Centra de Zoologia Aplicada, Fant/tad de Cien.cias Exactas, Fisicas y Naturales, Universidad Nacional de Cordoba, Casilla df Correo 122, 5000 C6rdoba, Argentina. Acceplecl for publication 5 November 1996. Summary - In Argentina, soil nematodes constitute a diverse group of invertebrates. This widely distributed group incJudes more than twO hundred currently valid species, among which the plant-parasitic and entomopathogenic nematodes are the most remarkable. The former includes species that cause damages to certain crops (mainly MeloicU:igyne spp, Nacobbus aberrans, Ditylenchus dipsaci, Tylenchulus semipenetrans, and Xiphinema index), the latter inc1udes various species of the Mermithidae family, and also the genera Steinernema and Helerorhabditis. There are few full-time nematologists in the country, and they work on taxonomy, distribution, host-parasite relationships, control, and different aspects of the biology of the major species. Due tO the importance of these organisms and the scarcity of information existing in Argentina about them, nematology can be considered a promising field for basic and applied research. Résumé - Les nématodes et l'agriculture en Argentine. Un aperçu général - Les nématodes du sol représentent en Argentine un groupe très diversifiè. Ayant une vaste répartition géographique, il comprend actuellement plus de deux cents espèces, celles parasitant les plantes et les insectes étant considèrées comme les plus importantes. Les espèces du genre Me/oi dogyne, ainsi que Nacobbus aberrans, Dùylenchus dipsaci, Tylenchulus semipenetrans et Xiphinema index représentent un réel danger pour certaines cultures. -

Tokorhabditis N. Gen
www.nature.com/scientificreports OPEN Tokorhabditis n. gen. (Rhabditida, Rhabditidae), a comparative nematode model for extremophilic living Natsumi Kanzaki1, Tatsuya Yamashita2, James Siho Lee3, Pei‑Yin Shih4,5, Erik J. Ragsdale6 & Ryoji Shinya2* Life in extreme environments is typically studied as a physiological problem, although the existence of extremophilic animals suggests that developmental and behavioral traits might also be adaptive in such environments. Here, we describe a new species of nematode, Tokorhabditis tufae, n. gen., n. sp., which was discovered from the alkaline, hypersaline, and arsenic‑rich locale of Mono Lake, California. The new species, which ofers a tractable model for studying animal‑specifc adaptations to extremophilic life, shows a combination of unusual reproductive and developmental traits. Like the recently described sister group Auanema, the species has a trioecious mating system comprising males, females, and self‑fertilizing hermaphrodites. Our description of the new genus thus reveals that the origin of this uncommon reproductive mode is even more ancient than previously assumed, and it presents a new comparator for the study of mating‑system transitions. However, unlike Auanema and almost all other known rhabditid nematodes, the new species is obligately live‑bearing, with embryos that grow in utero, suggesting maternal provisioning during development. Finally, our isolation of two additional, molecularly distinct strains of the new genus—specifcally from non‑extreme locales— establishes a comparative system for the study of extremophilic traits in this model. Extremophilic animals ofer a window into how development, sex, and behavior together enable resilience to inhospitable environments. A challenge to studying such animals has been to identify those amenable to labo- ratory investigation1,2. -

Nematodes are belongs to animal kingdom, they are triploblastic, unsegmented, bilateral symmetrical, pseudocoelomateandhaving well developed reproductive, nervous, excretoryand digestive system where as the circulatory and respiratory systems are absent but govern by the pseudocoelomic fluid. Plant Nematology: Nematology is a science deals with the study of morphology, taxonomy, classification, biology, symptomatology and management of {plant pathogenic} nematode (PPN). The word nematode is made up of two Greek words, Nema means thread like and eidos means form. The words Nematodes is derived from Greek words ‘Nema+oides’ meaning „Thread + form‟(thread like organism ) therefore, they also called threadworms. They are also known as roundworms because nematode body tubular is shape. The movement (serpentine) of nematodes like eel (marine fish), so also called them eelworm in U.K. and Nema in U.S.A. Roundworms by Zoologist Nematodes are a diverse group of organisms, which are found in many different environments. Approximately 50% of known nematode species are marine, 25% are free-living species found in soil or freshwater, 15% are parasites of animals, and 10% of known nematode species are parasites of plants (see figure at left). The study of nematodes has traditionally been viewed as three separate disciplines: (1) Helminthology dealing with the study of nematodes and other worms parasitic in vertebrates (mainly those of importance to human and veterinary medicine). -

Schifer1,2*† , Hiroshi Kagoshima3, Hideaki Hiraki3, Theresa Vogt1,5, Michael Kroiher1 , Yuji Kohara3 and Einhard Schierenberg1 Abstract Background: The free-living nematode Diploscapter coronatus is the closest known relative of Caenorhabditis elegans with parthenogenetic reproduction. It shows several developmental idiosyncracies, for example concerning the mode of reproduction, embryonic axis formation and early cleavage pattern (Lahl et al. in Int J Dev Biol 50:393–397, 2006). Our recent genome analysis (Hiraki et al. in BMC Genomics 18:478, 2017) provides a solid foundation to better understand the molecular basis of developmental idiosyncrasies in this species in an evolutionary context by com- parison with selected other nematodes. Our genomic data also yielded indications for the view that D. coronatus is a product of interspecies hybridization. Results: In a genomic comparison between D. coronatus, C. elegans, other representatives of the genus Caenorhab- ditis and the more distantly related Pristionchus pacifcus and Panagrellus redivivus, certain genes required for central developmental processes in C. elegans like control of meiosis and establishment of embryonic polarity were found to be restricted to the genus Caenorhabditis. The mRNA content of early D. coronatus embryos was sequenced and compared with similar stages in C. elegans and Ascaris suum. We identifed 350 gene families transcribed in the early embryo of D. coronatus but not in the other two nematodes. -
