Acetate: CoA ligase (AMP) (EC 6. 2. 1. 1, acetyl CoA synthetase, ACS) was found in sweet potato root tissue. When the tissue was infected by Ceratocystis fimbriata, activity of the enzyme was increased several-fold compared to that in fresh tissue and decreased rapidly after reaching a maximum. When cut tissue was incubated without inoculation, the activity was rather decreased.
The fact that terpenes such as ipomeamarone are synthesized in diseased tissue but not in cut tissue, strongly suggests that increased activity of ACS in diseased tissue mainly participates in terpene biosynthesis supplying acetyl CoA.
