Figure 5.
Quantitative RT-PCR expression analysis of MIT1 and MIT2 in shoots and roots of WT seedlings grown in standard B5 media for 2 weeks and then transferred to Fe-sufficient or Fe-deficient media for 3 days. The mRNA levels for both MIT1 and MIT2 from +Fe shoot was set at 1 and the relative abundance of the two transcripts were determined in the other tissues. Actin was used as a reference gene to normalize mRNA values. Values represent the mean of 3 biological replicates, and error bars indicate standard deviation. Significance (p < 0.05) was assessed using the Student’s t-test; significant differences in the transcript abundance between +Fe and −Fe shoots is represented by an asterisk.
