Hi, Mary. What sort of plant tissue are you working on?

Hi Martin, It is good to hear from you. I have read the paper you mentioned. The sentence about lack of correlation says that there is no correlation between filtrate inhibition of SCN and filtrate inhibition of RKN, which are two different types of nematodes. So, they are stating that fungi harvested from SCN produce compounds that specifically inhibit SCN without affecting RKN. The authors of this paper looked at fungi collected from SCN eggs. I am planning on investigating endophytes of soybean roots for similar properties. Below are citations for two papers that are guiding my research. One identifies endophytes that produce nematicidal toxins; the other suggests that endophyte co-cultures may produce more toxic compounds than single cultures, and that these compounds may be involved in plant defense against pathogens. In this case, they are testing the effectiveness of the co-culture filtrate to inhibit a fungal pathogen, but I plan to apply the same idea to nematodes, specifically SCN. 1. Hallmann J, Sikora RA. Toxicity of fungal endophyte secondary metabolites to plant parasitic nematodes and soil-borne plant pathogenic fungi. Eur J Plant Pathol 1996;102:155–62. 2. Chagas FO, Dias LG, Pupo MT. A Mixed Culture of Endophytic Fungi Increases Production of Antifungal Polyketides. J Chem Ecol 2013;39:1335–42.

Hi Martin, It's good to hear from you. Is this a school project? I came up with my hypotheses by thinking about the root environment and how fungi react when they are forced to live in close proximity to each other. There are reports in the literature of fungi increasing production of antibiotic-like compounds when they are grown together on the same Petri plate, so it is not a big leap to assume that something similar is going on inside plant roots, where many fungal species are living close to each other. Many antibiotic compounds are not only harmful to fungi but are also harmful to other microorganisms, including nematodes, so I hypothesized that fungal-fungal interactions inside soybean roots play a role in protecting the plants from the soybean cyst nematode. I would be happy to share some more pictures with you, but I would like to hear a little more about your presentation, first. Best, Noah
