From: The piperazine compound ASP activates an auxin response in Arabidopsis thaliana
Chemical genetics screening identified a novel compound ASP that produced abnormal leaf-vein pattern. a-b: Leaf vein pattern of 10-day-old seedlings of Q0990 line grown on 1/2 MS medium (a) and 1/2 MS medium with 10 μM ASP (b). c-d: Observation of 10-day-old seedlings of DR5::GFP reporter line grown on 1/2 MS medium (c) and 1/2 MS medium with 10 μM ASP (d) by confocal scanning laser microscope. E: Chemical structural formula of endogenous auxin indole-3-acetic acid (IAA), synthetic auxin 2,4-dichlorophenoxyacetic acid (2,4-D), and small-molecule compound 1-[(4-bromophenoxy) acetyl]-4-[(4-fluorophenyl) sulfonyl] piperazine (ASP)
