Th ey play a complex an d importan t role in the den dritic net work of the physiolog ical proces ses in plan ts. N ev er thel es s, a correl ation bet ween thei r chem ical structure an d its biolog ical implication could not be fou nd. Man y theor ies on correl ations of structure an d activity hav e been dev el oped, which are based mainly on chem ical intuition. Th is is the first ap proach to ap ply met hod s of computational chem istry combined with biostatistics. By the ap plication of thes e met hod s, the distribution of the outer molecular orbitals on the molecule can be iden tified an d also thei r impact on the biolog ical activity. Th e use of Mol ecular Quan tum Similarity Meas ures (MQSM) on structures of au xin-like molecules res ulted in a concep tual fram ew ork to classify au xin structures from a biostatistical point of view .
