UMAMIT14 mRNA accumulation in 5-week-old Arabidopsis plants grown in hydroponic conditions. UMAMIT14 mRNA levels were determined by qRT-PCR and normalized against ACTIN2 mRNA accumulation. UMAMIT14 mRNA levels are expressed relative to the wild-type (WT) root sample. Significant differences (P<0.05) are indicated by different letters according to one-way ANOVA in conjunction with Tukey’s test (two biological replicates)
