Fig 1. Modulation of harpin-triggered apoplastic alkalinisation by different auxins.

Fig 1

Cells were treated with 9 μg ml-1 harpin (hrp, closed circles) as a positive control, harpin combined with 10 μM (open triangles) or 50 μM auxins (IAA, NAA, or 2, 4-D, closed triangles), or ethanol used as solvent control (con, open circles) in V. rupestris (A, C, and E) and cv. ‘Pinot Noir’ (B, D, and F). Representative experiments from five biological replicas are depicted. Harpin and auxin were added at time 0, if measured isolated, for the combinations, auxins were added 1 h prior to harpin.
