Up‐regulation of the ethylene pathway in crt1a mutants. (a) Marker gene expression analysis by qPCR relative to wild type. Expression of PR1 for the salicylic acid pathway, PDF1.2 for the jasmonic acid pathway, NCED3 for abscisic acid and ETR2 for the ethylene pathway was investigated in both Arabidopsis crt1a (SALK_055452) and several OSR crt1a mutant backgrounds. (b) ET gene expression analysis in C3E3 plants by qPCR relative to wild type. Root material was harvested from 4‐week‐old Arabidopsis plants and 2‐week‐old Brassica napus plants. Statistical significance was checked on the basis of three independent biological replicates by Student's t‐test (*P ≤ 0.05; **P ≤ 0.01). (c) Simplified overview of the ET signalling pathway in plants (modified from Ju and Chang, 2015).
