A large difference was found in the activities of oligomycin‐sensitive mitochondrial F 0 F 1 ‐ATPase isolated from different tissues of Lilium longiflorum plants. The enzyme activity of F 0 F 1 ‐ATPase in pollen was the highest, while that in bulbs was the lowest. When ATPases were cross‐reconstituted from F 1 ‐ATPases and F 1 ‐depleted submitochondrial particles (SMP), ATPases reconstituted from F 1 ‐depleted pollen SMP showed the higher activity regardless of the source of F 1 ‐ATPase. Fatty acid compositions of phospholipids in SMP were also different between bulbs and pollen. These suggest that the F 0 portion and/or its environment are important for regulation of F 0 F 1 ‐ATPase activity in L. longiflorum plant.
