Effect of fungal and oomycetal volatiles on Collimonas pratensis Ter291 and Serratia plymuthica PRI-2C swarming motility (0.6% wt/vol agar) and swimming motility (0.3% wt/vol agar) on water agar supplied with artificial root exudates (A) and potato dextrose agar (B). Setup of experiment and effect of FC and RS volatiles on swimming motility of C. pratensis Ter291 and S. plymuthica PRI-2C (C). MH, M. hiemalis; RS, R. solani; PU, P. ultimum; VD, V. dahliae; FC, F. culmorum; TH, T. harzianum, Control: media. Five microliters of washed overnight cultures of C. pratensis Ter291 and S. plymuthica PRI-2C was spotted in the center of a soft agar partitioned Petri dish containing the fungal and oomycetal strains and incubated for 3 days at 20°C. As an indicator of motility the average swimming and swarming diameter (cm) was measured. The error bars represent standard errors of the mean of three independent biological replicates. The asterisks indicate statistically significant (P < 0.05) differences relative to the control.
