ACC dimer induces the triple response phenotype in Arabidopsis. (A) The molecular structures of ACC and its dipeptide di-ACC. (B) Representative images and (C,D) quantification of hypocotyl (C) and root length (D) of 4-day-old dark-grown seedlings grown on medium containing ACC or di-ACC (n ≥ 54). (E,F) Quantification of hypocotyl (E) and root length (F) in a triple response assays after boiling di-ACC for 1 h prior to addition to the culture media (n ≥ 29). (G) In planta ethylene production of 4-day-old dark-grown seedlings treated with ACC or di-ACC (n = 5). Scale bar in (B) is 1 mm.
