Fig. 6From: The piperazine compound ASP activates an auxin response in Arabidopsis thalianaRT-qPCR expression analyses of early auxin response genes. Six-day-old seedlings were treated with 5 μM ASP and 5 μM IAA for 0.5–2 h. Expression level shown are the Means ± SD from three biological replicates for each.
