Expression of DK-ACS and DK-ACO gene families during ripening in persimmon fruit. Fruit harvested at mature stage (156 d AFB) were held at 20°C in ambient laboratory humidity for 30 d or treated with 50 μL L⁻¹ of exogenous ethylene for 2 d. Lane 1, Fruit at harvest; lane 2, fruit held for 30 d; lane 3, ethylene-treated fruit. Each lane contained 5 μg of total RNA, and the transcript levels of 17S rRNA are shown as an internal loading control.
