text: "Auxin belongs among major phytohormones and governs multiple aspects of plant
growth and development. The establishment of auxin concentration gradients, determines,
among other processes, plant organ positioning and growth responses to environmental
stimuli.\r\nHerein we report the synthesis of new NBD- or DNS-labelled IAA derivatives
and the elucidation of their biological activity, fluorescence properties and
subcellular accumulation patterns in planta. These novel compounds did not show
auxin-like activity, but instead antagonized physiological auxin effects. The
DNS-labelled derivatives FL5 and FL6 showed strong anti-auxin activity in roots
and hypocotyls, which also occurred at the level of gene transcription as confirmed
by quantitative PCR analysis. The auxin antagonism of our derivatives was further
demonstrated in vitro using an SPR-based binding assay. The NBD-labelled compound
FL4 with the best fluorescence properties proved to be unsuitable to study auxin
accumulation patterns in planta. On the other hand, the strongest anti-auxin activity
possessing compounds FL5 and FL6 could be useful to study binding mechanisms to
auxin receptors and for manipulations of auxin-regulated processes."
