From: Oxygen transfer rate identifies priming compounds in parsley cells
Pep13 dose-dependent respiratory responses of parsley cell suspension cultures. Oxygen transfer rate (OTR) as a function of time for three Pep13 concentrations and a reference without additives (black squares). Addition of 100 μM SA and 100 pM Pep13 (closed dark green circles), 100 μM SA and 50 pM Pep13 (left half green circles), and 100 μM SA and 1 pM Pep13 (open light green circles). Arrows indicate the addition of SA and Pep13. Cultivation conditions: 250 mL flask volume, 50 mL filling volume, 180 rpm shaking frequency, 50 mm shaking diameter, and 25 °C
