Figure 3.
Primary root elongation of NIT1ox compared to nit1-3, NIT2RNAi, and wild-type seedlings. Root elongation was quantified in 2 week-old seedlings grown on vertical plates. Seedlings were removed from the Petri dishes, and root length was recorded. At least 15 seedlings of each genotype were measured for each condition. Error bars indicate the standard error of the mean. Asterisks indicate significant differences between Col-0 and the different tested genotypes (**p < 0.001; Student's t-test).
