Figure 4. Gene expression of Fe deficiency response genes in various SA mutants and wild type plants.

Figure 4

A, FIT, FRO2, IRT1; B, BHLH38, BHLH39; SA mutants and wild type seedlings were grown for 11 d at + and −Fe. Roots were harvested for analysis. n = 2; * indicates a significant change (p<0.05) of −Fe versus +Fe; + indicates a significant change (p<0.05) of SA mutant versus WT. Gene expression was studied using reverse transcription-qPCR.
