Figures & data
Figure 1. Nicotine, nornicotine, and anabasine concentrations in leaves and roots of Nicotiana tabacum plants after 3 or 10 days of elicitor solution applications (Control – plants without elicitor solution application; GS – elicitor solution from germinating spore exudates; and DS – elicitor solution from disrupted AMF spores). Different lower case letters denote statistically significant differences among treatments in leaves or roots, and uppercase letters are used to compare total (leaves + roots) alkaloid contents by the Tukey's test (5%). Error bars show the standard deviation (n=4).
Figure 2. Relative transcript levels of tobacco alkaloid related-enzymes in relation to elongation factor EF-1α transcript levels in roots of Nicotiana tabacum plants after 3 or 10 days of elicitor solution applications (Control – plants without elicitor solution application; GS – elicitor solution from germinating spore exudates; and DS – elicitor solution from disrupted AMF spores). Significant differences among treatments at P<0.05 were determined by one-way analysis of variance (ANOVA) followed by the Tukey's test and are indicated by different letters. Error bars show the standard deviation (n=4).
