AtSARK-induced changes in the expression of cytokinin-related (A), auxin-related (B), and ethylene-related (C) genes were suppressed by the overexpression of SSPP in Arabidopsis. The transcript levels of the hormone-related genes were determined by quantitative RT-PCR. Four-day-old GVG:GUS (G28), GVG:AtSARK (AtS20), 35S:SSPP, and 35S:SSPP/GVG:AtSARK transgenic seedlings were treated with either 10 μm
DEX or its mock solution for 24 h. TIP41-like was used as an internal control. In all cases, data are shown relative to the mock-treated control. Three biological replicates with at least three technical repeats were done.
