Abstract
With the cytochrome pathway inhibited, AOX was able to support conside rable growth of cultured tobacco (Nicotiana tabacum cv Petit Havana SR 1) cells but the efficiency of carbon utilization decreased dramatical ly. Antisense cells with decreased AOX protein did not grow, whereas s ense cells with elevated AOX protein had higher growth and respiration rates than the wild type. In antisense cells a large accumulation of pyruvate resulted in aerobic ethanolic fermentation.
