Changes in ADH enzyme activity and mRNA amounts from specific genes in response to CO₂ treatment. Mature fruit were treated with CO₂ (~95%, v/v, open diamonds, 1 d) and air (control, open squares), separately. The horizontal arrow represents the end day of the treatment, when the fruit were transferred to air at 20 °C. Day 0 fruit values were set as 1. Black columns and white columns represent relative mRNA abundance of the gene transcripts in control and ethylene treated fruit, respectively. Error bars indicate SEs from three biological replicates.
