Auxin responsiveness of DzARF2A. Fold changes in expression level of DzARF2A in young leaves of Monthong cultivar treated with 0 (control), 10, 20, and 40 μM IAA for 1 and 2 h were calculated by using the 2-ΔΔCt method and levels were normalized by the geometric mean of reference genes and the control samples (0 μM IAA). Three independent biological replicates were used for each condition at each timepoint. Different letters indicate significant differences (P < 0.05). Comparisons were also made for each condition between the two timepoints; an asterisk (*) above the bars indicates a significant difference for that condition between 1 and 2 h (P < 0.05).
