Staff Nematologist Wanted A&L Southern Agricultural Laboratories
in Pompano Beach, Florida, USA will have the position of staff nematologist
opening up, approximately April 1st, 2002, or shortly thereafter. The position
involves extraction of plant parasitic nematodes from soil sampling, using
sugar flotation, and identification to genus using an invert microscope.
Parasitic types are quantified per 100 cc of soil, in the normal manner
with a grid counter.

Postdoctoral Position A supported postdoctoral position is currently available in the Aroian Laboratory for a unique and exciting study on the potential of controlling plant-parasitic nematodes with Bacillus thuringiensis toxins and the interaction of the bacterial toxins with nematode pests. Plant-parasitic nematodes cause >$80 billion of damage per year and account for 10% crop loss worldwide. Our laboratory is the first to study the effects of cloned Bacillus thuringiensis toxin genes on nematodes (see Science, 2001, vol. 293 pp. 860-864). We are looking for dynamic, talented scientists to study the potential to use these natural toxins to control plant-parasitic nematodes and to study interactions between toxins and the nematodes. Study involves molecular studies to improve toxin genes, transgenic root and plant work, and studies of genomic response of plants to nematode infection. Applicants should have a strong background in molecular biology and preferably experience working with plants. U.C. San Diego is a leader in plant biology research and is situated in a vibrant city that is also host to excellent biology and biotechnology communities. Interested candidates should submit a cover letter, curriculum vitae, and the names of three references to Dr. Raffi V. Aroian, Section of Cell and Developmental Biology, University of California, San Diego, La Jolla, CA 92093-0349, fax 858-822-2003, email raroian@ucsd.edu (send attachments in rich text format only). posted 01/14/02
We are determining the responses of the larvae of the Greater wax moth, Galleria mellonella to micro-organisms. The main thrust is the identification of the effects of the plasma protein, apolipophorin-III on the hemocytes to the bacteria Xenorhabdus nematophilus and Bacillus subtilis. The objective is to increase the effectiveness of the bacterial-nematode complex, Xenorhabdus-Steinernema as a microbial insecticide. Dedicated and reliable graduated students are beiing sought for two projects. 1. The candidate will identify enzymes discharged from hemocytes in response to bacterial antigens. The influence of apolipophorin-III on these activities will be determined. 2. The candidate will establish the influence of bacterial antigens and apolipophorin-III on signal transduction in hemocytes. Candidates must have an interest in physiology, cell biology and biochemistry. Experience with insects and bacteria is not essential but useful. Two letters of reference are required. Contact Gary B.
