Auxins are plant hormones governing many biological processes in higher plants such as cell enlargement and division, differentiation of vascular tissue, apical dominance, root initiation and signaling.
    Indole-3-acetic acid (IAA, see Fig. above) is the most commonly occurring natural auxin.
    Here we present a 3D library of auxin related compounds.
The classification of auxins and their analogues into four classes is based on similarity analysis of their interaction properties and measured biological activities.
