Factors affecting soil microbial community structure in tomato cropping systems
The imposed treatments were much more significant than soil temperature, moisture, pH, and texture in controlling microbial biomass and community structure in a tomato production agroecosystem. Expand
Nematode suppression with brassicaceous amendments: application based upon glucosinolate profiles
It is found that brassicaceous amendments can be applied to achieve consistent and repeatable nematode suppression when based upon the chemistry of the incorporated material. Expand

An overview of nematode management practices that are believed to be relied upon heavily in U.S. high-value crop production systems in a world without methyl bromide is provided. Expand
Effects of organic amendment and tillage on soil microorganisms and microfauna
The results of this study suggest that when combined with amendment, tillage enhances the soil food web beyond the effect of amendment alone and is associated with declines in plant-parasitic nematodes. Expand
Sensitivity of Meloidogyne javanica and Tylenchulus semipenetrans to Isothiocyanates in Laboratory Assays.
Brassicaceous sources of benzyl or 2-phenylethyl isothiocyanate and, to a lesser extent allyl isothermate, are the most promising candidates for plant-parasitic nematode management. Expand
Microbial community structure and abundance in the rhizosphere and bulk soil of a tomato cropping system that includes cover crops
Season of the year had the strongest influence on the soil microbial community structure of some of the major microbial phyla, and it was found that the effects of the tomato plant on the structural composition of these phyla in the rhizosphere differed dependent on the antecedent cover crop.

Comparative Genomics of a Plant-Parasitic Nematode Endosymbiont Suggest a Role in Nutritional Symbiosis

- 1 September 2015
Together, features and the location in the gut suggest that Xiphinematobacter functions as a nutritional mutualist, supplementing essential nutrients that are depleted in the nematode diet, which points to evolutionary convergence with endosymbionts found in sap-feeding insects. Expand
Genomic evidence for plant-parasitic nematodes as the earliest Wolbachia hosts

- Scientific reports
- 13 October 2016
The genome of a new Wolbachia strain in the plant-parasitic nematode Pratylenchus penetrans is sequenced and analyzed, enhancing understanding of this globally pandemic endosymbiont and highlighting genetic patterns associated with host changes. Expand
Dose-response effects of clove oil from Syzygium aromaticum on the root-knot nematode Meloidogyne incognita.

The results demonstrated that the tested formulation is active against M. incognita eggs and J2, that the EC(50) values for J2 in the microwell studies and the soil recovery tests were similar to each other and that direct contact with the clove oil is needed for optimal management results with this natural product. Expand
Identification of candidate effector genes of Pratylenchus penetrans.
The spatial expression of transcripts of 22 candidate effectors within the oesophageal glands of P. penetrans is determined, providing valuable data to elucidate the mode of parasitism of this nematode and offers useful suggestions regarding the potential use of P-penetran-specific target effector genes to control this important pathogen.
