Table 2. Rhizophagus irregularis ( = Glomus intraradices) mycorrhization of transgenic control and CgCCamK knock-down roots.

	Number of plants	Mycorrhization frequency (%)
TC	10	41.01 (±8.49)
RNAi-CAM	20	8.09 (±2.14)
RNAi-UTR	15	5.03 (±1.39)

Mycorrhization frequency corresponds to the percentage of mycorrhized roots in 10 TC (transgenic control) plants, 20 RNAi-CAM plants and 15 RNAi-UTR plants evaluated using the gridline intercept method. Mycorrhization frequency was calculated using roots harvested 9 weeks post inoculation. Standard errors are in brackets.
