POPULATION VARIABILITY OF ROTYLENCHULUS RENIFORMIS IN COTTON AGROECOSYSTEMS A Dissertation Presented to the Graduate School of Clemson University In Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy Plant and Environmental Sciences by Megan Marie Leach December 2010 Accepted by: Dr. Paula Agudelo, Committee Chair Dr. Halina Knap Dr. John Mueller Dr. Amy Lawton-Rauh Dr. Emerson Shipe i ABSTRACT Rotylenchulus reniformis, reniform nematode, is a highly variable species and an economically important pest in many cotton fields across the southeast. Rotation to resistant or poor host crops is a prescribed method for management of reniform nematode. An increase in the incidence and prevalence of the nematode in the United States has been reported over the -
The Complete Mitochondrial Genome of the Columbia Lance Nematode
Ma et al. Parasites Vectors (2020) 13:321 https://doi.org/10.1186/s13071-020-04187-y Parasites & Vectors RESEARCH Open Access The complete mitochondrial genome of the Columbia lance nematode, Hoplolaimus columbus, a major agricultural pathogen in North America Xinyuan Ma1, Paula Agudelo1, Vincent P. Richards2 and J. Antonio Baeza2,3,4* Abstract Background: The plant-parasitic nematode Hoplolaimus columbus is a pathogen that uses a wide range of hosts and causes substantial yield loss in agricultural felds in North America. This study describes, for the frst time, the complete mitochondrial genome of H. columbus from South Carolina, USA. Methods: The mitogenome of H. columbus was assembled from Illumina 300 bp pair-end reads. It was annotated and compared to other published mitogenomes of plant-parasitic nematodes in the superfamily Tylenchoidea. The phylogenetic relationships between H. columbus and other 6 genera of plant-parasitic nematodes were examined using protein-coding genes (PCGs). Results: The mitogenome of H. columbus is a circular AT-rich DNA molecule 25,228 bp in length. The annotation result comprises 12 PCGs, 2 ribosomal RNA genes, and 19 transfer RNA genes. No atp8 gene was found in the mitog- enome of H. columbus but long non-coding regions were observed in agreement to that reported for other plant- parasitic nematodes. The mitogenomic phylogeny of plant-parasitic nematodes in the superfamily Tylenchoidea agreed with previous molecular phylogenies. Mitochondrial gene synteny in H. columbus was unique but similar to that reported for other closely related species. Conclusions: The mitogenome of H. columbus is unique within the superfamily Tylenchoidea but exhibits similarities in both gene content and synteny to other closely related nematodes. -

These possibilities of having the editors working alongside provide an efficient work in a shorter time. We definitely need to have these workshops periodically. The objectives of this workshop were: (i) to evaluate the work that has been done over the past three years and the maintenance of the database, (ii) to welcome the editors of terrestrial and fresh water nematodes, set clear goals, assign tasks and initiate the practical work related to new initiatives and (iii) to outline practices for outreach and scientific output for Nemys (e.g. scientific papers, presentations of the progress, plans and results at an upcoming conference). On the first day it was asked to have a rapporteur for each session in order to have it registered. The original minutes are on a separate document and were used to generate this report.

131 Nematode Fauna of Costa Rican Protected Areas
NEMATODE FAUNA OF COSTA RICAN PROTECTED AREAS Alejandro Esquivel Universidad Nacional de Heredia (U.N.A), Apdo postal 86-3000 Heredia, Costa Rica. ABSTRACT Esquivel, A. 2003. Nematode fauna of Costa Rican protected areas. Nematropica 33:131-145. The Instituto Nacional de Biodiversidad (INBio), in collaboration with the Nematology Laborato- ry at Universidad Nacional (U.N.A) of Costa Rica, conducted a nematode inventory of Costa Rican wild lands. Hundreds of samples were randomly collected for nematode analyses and thousands of specimens were permanently mounted on Cobb slides. A total of 74 families, 231 genera and 105 spe- cies has been detected so far. Dorylaimida was the dominant order both in number of specimens and genera, while the least dominant orders were Aphelenchida, Monhysterida and Desmocolecida. Some nematodes were widely distributed across all microhabitats, others appeared be restricted to a specific microhabitat or ecosystem. Basic and advanced reports regarding nematode inventory in Cos- ta Rican protected areas can be requested through the web page of INBio (http://atta.inbio.ac.cr). Key words: biodiversity, conservation areas, inventory, nematodes, survey. RESUMEN Esquivel, A. 2003. Nematofauna de las áreas protegidas de Costa Rica. Nematropica 33:131-145.

Sensitivity of Ribosomal RNA Character Sampling in the Phylogeny of Rhabditida
Journal of Nematology 47(4):337–355. 2015. Ó The Society of Nematologists 2015. Sensitivity of Ribosomal RNA Character Sampling in the Phylogeny of Rhabditida 1 2 2 OLEKSANDR HOLOVACHOV, LAUREN CAMP, AND STEVEN A. NADLER Abstract: Near-full-length 18S and 28S rRNA gene sequences were obtained for 33 nematode species. Datasets were constructed based on secondary structure and progressive multiple alignments, and clades were compared for phylogenies inferred by Bayesian and maximum likelihood methods. Clade comparisons were also made following removal of ambiguously aligned sites as determined using the program ProAlign. Different alignments of these data produced tree topologies that differed, sometimes markedly, when analyzed by the same inference method. With one exception, the same alignment produced an identical tree topology when analyzed by different methods. Removal of ambiguously aligned sites altered the tree topology and also reduced resolution. Nematode clades were sensitive to differences in multiple alignments, and more than doubling the amount of sequence data by addition of 28S rRNA did not fully mitigate this result. Although some individual clades showed substantially higher support when 28S data were combined with 18S data, the combined analysis yielded no statistically significant increases in the number of clades receiving higher support when compared to the 18S data alone. Secondary structure alignment increased accuracy in positional homology assignment and, when used in combination with paired-site substitution models, these structural hypotheses of characters and improved models of character state change yielded high levels of phylogenetic resolution. Phylogenetic results included strong support for inclusion of Daubaylia potomaca within Cephalobidae, whereas the position of Fescia grossa within Tylenchina varied depending on the alignment, and the relationships among Rhabditidae, Diplogastridae, and Bunonematidae were not resolved. -

Phylogenetic and Population Genetic Studies on Some Insect and Plant Associated Nematodes
PHYLOGENETIC AND POPULATION GENETIC STUDIES ON SOME INSECT AND PLANT ASSOCIATED NEMATODES DISSERTATION Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Amr T. M. Saeb, M.S. * * * * * The Ohio State University 2006 Dissertation Committee: Professor Parwinder S. Grewal, Adviser Professor Sally A. Miller Professor Sophien Kamoun Professor Michael A. Ellis Approved by Adviser Plant Pathology Graduate Program Abstract: Throughout the evolutionary time, nine families of nematodes have been found to have close associations with insects. These nematodes either have a passive relationship with their insect hosts and use it as a vector to reach their primary hosts or they attack and invade their insect partners then kill, sterilize or alter their development. In this work I used the internal transcribed spacer 1 of ribosomal DNA (ITS1-rDNA) and the mitochondrial genes cytochrome oxidase subunit I (cox1) and NADH dehydrogenase subunit 4 (nd4) genes to investigate genetic diversity and phylogeny of six species of the entomopathogenic nematode Heterorhabditis. Generally, cox1 sequences showed higher levels of genetic variation, larger number of phylogenetically informative characters, more variable sites and more reliable parsimony trees compared to ITS1-rDNA and nd4. The ITS1-rDNA phylogenetic trees suggested the division of the unknown isolates into two major phylogenetic groups: the HP88 group and the Oswego group. All cox1 based phylogenetic trees agreed for the division of unknown isolates into three phylogenetic groups: KMD10 and GPS5 and the HP88 group containing the remaining 11 isolates. KMD10, GPS5 represent potentially new taxa. The cox1 analysis also suggested that HP88 is divided into two subgroups: the GPS11 group and the Oswego subgroup. -
