Model explaining the promotion by exogenous IBA (10 μM) of AR formation in arabidopsis TCLs. Nitric oxide (NO) formed during the exogenous IBA-to-IAA conversion by ECH2/IBR10 induces the synthesis of JA, which, in turn, induces ASA1/ASB1 activity. The IAA, coming from IBA conversion and biosynthesis by ASA1/ASB1, is transported into the target cells of the rhizogenic process by the efflux carrier PIN1 and the influx carriers AUX1 and LAX3. NO might also positively affect PIN1 and AUX1, enhancing the endogenous IAA transport required for adventitious rooting. (See the text for further explanations)
