Variation in spacer ribosornal DNA in sorne cyst-forming species of plant parasitic nernatodes
Summary - Partial sequences from internal transcribed spacer ribosomal DNA (ITS rDNA) obtained by polymerase chain reaction (PCR) from isolates of plant parasitic cyst nematodes, were compared with… Expand
Regional Assessment of Soybean Brown Stem Rot, Phytophthora sojae, and Heterodera glycines Using Area-Frame Sampling: Prevalence and Effects of Tillage.
ABSTRACT The prevalence of brown stem rot (caused by Phialophora gregata), Heterodera glycines, and Phytophthora sojae in the north central United States was investigated during the fall of 1995 and… Expand
Comparisons of Isolates of Heterodera avenae using 2-D PAGE Protein Patterns and Ribosomal DNA.
Six geographic isolates of Heterodera avenae, including two isolates each from Sweden, Australia, and the United States, were compared on the basis of 2-D PAGE protein patterns and the complete DNA… Expand

Soybean cyst nematode (SCN) is a major soybean yield-limiting pest. The present study was conducted to map broad-based SCN resistance loci from the cultivar ‘Hartwig’. Two-hundred F2∶3 lines derived… Expand
Coprovision: Citizen Time and Money Donations in Public Service Provision
- J. M. Ferris
- 1 July 1984
Recent policies to limit government spending and taxing as embodied in California's Proposition 13 and Massachusetts' Proposition 21/2 have squeezed local governments financially. With similar… Expand
An Efficient New Device to Release Eggs From Heterodera glycines.
A new apparatus to release eggs from cysts of soybean cyst nematode (Heterodera glycines) is described and its efficiency evaluated. A rubber stopper was mounted on a bolt, and cysts were ground… Expand
Phylogenetic Relationships of Globodera millefolii, G. artemisiae, and Cactodera salina Based on ITS Region of Ribosomal DNA.
Globodera millefolii and G. artemisiae are interesting because their type localities (Estonia and Russia, respectively) are geographically distant from those of the potato cyst nematodes and other… Expand
Population Development of Pratylenchus hexincisus in Eight Corn Inbreds.
Of eight corn inbreds tested in the greenhouse and field, three (H60, H95, and H84) supported lower populations of Pratylenchus hexincisus than other inbreds included in this study. No apparent… Expand
