From: Potent Attractant for Root-Knot Nematodes in Exudates from Seedling Root Tips of Two Host Species
Exclusion chromatography of tomato root exudate (TRE) and Medicago root exudate (MRE). The four chromatograms are from separate runs on the same Bio-Gel P2 column. Chromatography was of (a) vitamin B12 and TRE, (b), dextran 40, vitamin B12, raffinose and ribose, (c) vitamin B12 and MRE, and (d) dextran 40, vitamin B12 and maltose. Attraction assay results are presented as a chemotaxis index, CI. Results from standards are concentrations expressed as a fraction of the applied concentration. For attraction assays, each bar represents the average of 3 replicate assays with SD shown.
