Fig. 5From: A natural frameshift mutation in Campanula EIL2 correlates with ethylene insensitivity in flowersExpression of ERS2 (b), CTR1 (c) and EIL1 (d) in Campanula in response to transient ethylene exposure. As reference gene Actin (ACT (a)) from Campanula was used. Ethylene was supplied to sealed glass tanks in the following concentrations; 0 μL · L−1 (0), 0.025 μL · L−1 (0.025) and 0.050 μL · L−1 (0.050) ethylene. The presented Campanula species are C. portenschlagiana (Cp), C. formanekiana (Cf) and C. medium (Cm). Flowers were marked the day before flower opening; the experiments started the following day (with 1-day old flowers) and were allowed to proceed for 24 hBack to article page
