Figure 2

Endogenous and AB-induced ethylene production of Samsun NN tobacco and four primary etr1–1 transformants. Relative ethylene levels are expressed as a percentage of endogenous ethylene production of Samsun NN plants. Insert shows an expanded view of the endogenous ethylene levels. A relative ethylene production rate of 1 corresponds to 0.12 nmol ethylene/g fresh weight per hr.
