Expression of PA-PPO gene during ripening of apricot fruit. Fifteen micrograms of total RNA from apricot fruit was used at five stages of development: IM1 (immature green 1), BR (breaker), BR⁺ (breaker +), HR (half-ripe), and OR (overripe). The blot was hybridized to an RT-PCR PPO fragment from apricot and washed at high stringency.
