The regulation of the TaPHO2 transcripts by tae-miR399 and TaIPS1.
The relative expression levels of TaPHO2 (a), tae-miR399-A1 (b) and TaIPS1 (c) in the tobacco leaves transiently overexpressed the indicated gene(s). The expression of TaPHO2 was presented as percentage of that in the control leaves which were transformed with TaPHO2-A1, -B1 or -D1 alone, the relative expression levels of tae-miR399-A1 and TaIPS1 were normalized using the expression of NtACTIN. Different letters in (a) indicate significant difference at P < 0.05 level by Student’s t test. Error bars indicate SE (n = 6).
