Thomas Powers et al.
DNA barcodes are increasingly used to provide an estimate of biodiversity for small, cryptic organisms like nematodes. Nucleotide sequences generated by the barcoding process are often grouped, based on similarity, into molecular operationa...
Molecular Characterization and Phylogenetic Analysis of Hoplolaimus stephanus [0.03%]
Hoplolaimus stephanus线粒体基因组的分子特征及系统发育分析
Xinyuan Ma,Paula Agudelo,John D Mueller et al.
Xinyuan Ma et al.
Three Hoplolaimus stephanus populations were characterized morphologically, both by morphometrics and by SEM observations. These populations were used to develop a rapid and accurate molecular identification method for the species, which is...
Probability of detecting nematode infestations for quarantine sampling with imperfect extraction efficacy [0.03%]
不完美的提取效果检疫抽样检测线虫侵染的概率
Peichen Chen,Shih-Chia Liu,Hung-I Liu et al.
Peichen Chen et al.
For quarantine sampling, it is of fundamental importance to determine the probability of finding an infestation when a specified number of units are inspected. In general, current sampling procedures assume 100% probability (perfect) of det...
Mustard seed meal mixtures: management of Meloidogyne incognita on pepper and potential phytotoxicity [0.03%]
芥末籽粉混合物对辣椒上南方根结线虫的管理及其潜在的植物毒性
Susan L F Meyer,Inga A Zasada,Samuel B Orisajo et al.
Susan L F Meyer et al.
Meals produced when oil is extracted from seeds in the Brassicaceae have been shown to suppress weeds and soilborne pathogens. These seed meals are commonly used individually as soil amendments; the goal of this research was to evaluate see...
Effects of the nematicide imicyafos on soil nematode community structure and damage to radish caused by Pratylenchus penetrans [0.03%]
杀线虫剂imidacloprid对土壤线虫群落结构的影响及对由Pratylenchus penetrans引起的萝卜损伤影响

Satoko Wada
The effects of the non-fumigant nematicide imicyafos on soil nematode community structure and damage to radish caused by Pratylenchus penetrans were evaluated in two field experiments in consecutive years (2007 and 2008). Nematode densities...
Molecular rDNA phylogeny of Telotylenchidae Siddiqi, 1960 and evaluation of tail termini [0.03%]

L K Carta
Three stunt nematode species, Tylenchorhynchus leviterminalis, T. dubius and T. claytoni were characterized with segments of small subunit 18S and large subunit 28S rDNA sequence and placed in molecular phylogenetic context with other polyp...
Inheritance of Resistance to Meloidoygne incognita in Primitive Cotton Accessions from Mexico [0.03%]
墨西哥原始棉属种质材料抗卵菌纺锤茎枯病的遗传研究
J L Starr,E R Moresco,C W Smith et al.
J L Starr et al.
Few sources of resistance to root-knot nematodes (Meloidogyne incognita) in upland cotton (Gossypium hirsutum) have been utilized to develop resistant cultivars, making this resistance vulnerable to virulence in the pathogen population. The...
Identification and molecular characterization of a β-1,4-endoglucanase gene (Rr-eng-1) from Rotylenchulus reniformis [0.03%]
肾形短体线虫β-1,4-内切葡萄糖苷酶基因(Rr-eng-1)的鉴定及分子特性分析
Martin J Wubben,Satish Ganji,Franklin E Callahan
Martin J Wubben
β-1,4-endoglucanses, a.k.a. cellulases, are parasitism genes that facilitate root penetration and migration by plant-parasitic nematodes. Rotylenchulus reniformis is a sedentary semi-endoparasite for which little molecular data has been co...
Population Dynamics and Dispersal of Aphelenchoides fragariae in Nursery-grown Lantana [0.03%]
繁殖场兰花种苗中蚜伦小杆线虫的种群动态及扩散能力研究
Lisa M Kohl,Colleen Y Warfield,D Michael Benson
Lisa M Kohl
Population dynamics of Aphelenchoides fragariae were assessed over three growing seasons and during overwintering for naturally-infected, container-grown lantana (Latana camara) plants in a North Carolina nursery. During the growing season,...
Effect of Storage Temperature on Soil Nematode Community Structures as Revealed by PCR-DGGE [0.03%]
基于PCR-RFLP技术的贮藏温度对土壤线虫群落结构的影响
