Responses to exogenous SA. a Detached leaves of six-weeks-old seedlings of nbl1 and wild-type plants were immersed in buffer solution (3 mM MES, pH 5.8) with 0 μM (Mock) or 100 μM SA for 6 days at room temperature (24 h light). Photographed at 4 days and 6 days. b-d Phenotypes of nbl1 and wild-type seedlings grown on the 1/2 MS containing the indicated concentrations of SA for 6 days B). Measurement the shoot and root length of nbl1 and WT plants, then calculation the inhibitory ratio of shoots length (c) and roots length (d), respectively
