Colonization of canola roots by Heteroconium chaetospira strain BC2HB1 (Hc) based on qPCR, with or without inoculation with Plasmodiophora brassicae (n = 9).

xPlants receiving no BC2HB1 were used as a negative control, and H. chaetospira DNA was not detected in roots of control plants.y2×105 resting spores pot−1. The data for 0 and 7 DAS were pooled within each repetition.zData from repeated trials were pooled for analysis. Means followed by the same letter do not differ (protected LSD at P≤0.05).
