The Baum Lab, Plant Pathology Department, Iowa State University, Ames. Research in the Baum lab focuses on the compatible interaction between cyst nematodes and their hosts with particular emphasis on the soybean cyst nematode (Heterodera glycines). They are working to characterize the signal transduction events leading to successful nematode establishment and parasitism. This includes characterization of changes in soybean and nematode gene expression during the different phases of parasitism. Furthermore, Arabidopsis thaliana mutants are screened for altered susceptibility to cyst nematodes with the goal of identifying and characterizing relevant genes. Available Information: Introduction, projects, personnel, available positions in the Lab.

INRA Plant Nematology Team, Institut National de la Recherche Agronomique (INRA), Le Rheu, France. The nematological studies are articulated around four major axes of researches aiming to the analysis of the plant/nematode interaction. Research areas : Nematodes identification, Characterization of virulence genes, Population genetics, Creation of nematode resistant varieties. These studies should lead both to some agronomic applications in resistant cultivars management and to some biotechnical applications in plant protection. Further available : personnel of the lab, geographic localisation, links, english and french versions.

Laboratory of Nematology, Wageningen Agricultural University (WAU), Netherlands.
