Diagram explaining how auxins regulate the process of plant grafting. It is a conclusion diagram, based on the various studies mentioned in the section related to auxins. PIN-FORMED auxin transport proteins (PINs); ATP-binding cassette subfamily B (ABCB); polar auxin transport (PAT); cytokinin (CK); gibberellins (GA); graft union (GU); LIKE AUXIN RESISTANT1-3 (LAX); HIGH CAMBIAL ACTIVITY2 (HCA2); ABERRANT LATERAL ROOT FORMATION 4 (ALF4).
