Ethylene induced plant stress tolerance by Enterobacter sp. SA187 is mediated by 2‐keto‐4‐methylthiobutyric acid production
Fig 6
SA187 modulates abscisic acid, jasmonic acid, and ethylene hormonal pathways under salt stress.
(A) Salicylic acid (SA), (B) abscisic acid (ABA) and (C) jasmonic acid (JA) content in mock- and SA187-inoculated plants after growth on ½ MS with or without 100 mM NaCl for 12 days. Error bars indicate SE, based on three biological replicates. Asterisks indicate a statistical difference based on the Mann-Whitney test (* P < 0.05). (D) The ethylene reporter, pEBF2::GUS, visualizing the relative ethylene content in primary root tips of mock- and SA187-inoculated, and ACC-treated 7-day-old seedlings under normal conditions (salt stress conditions provided similar results). Bar = 100 μm.
