From: Oxygen transfer rate identifies priming compounds in parsley cells
Respiratory responses of parsley cell suspension cultures dependent on the SA concentration. Oxygen transfer rate (OTR) as a function of time for three salicylic acid (SA) concentrations and a reference without additives (black squares). 10 μM SA and 50 pM Pep13 (open light blue circles), 50 μM SA and 50 pM Pep13 (left half blue circles), and 100 μM SA and 50 pM Pep13 (closed dark blue diamonds). Arrows indicate the addition of SA after 72 h and Pep13 after 96 h. Cultivation conditions: 250 mL flask volume, 50 mL filling volume, 180 rpm shaking frequency, 50 mm shaking diameter, and 25 °C
