摘要：

A large difference was found in the activities of oligomycin-sensitive mitochondrial F0F1-ATPase isolated from different tissues of Lilium longiflorum plants. The enzyme activity of F0F1-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 F0F1-ATPase activity in L. longiflorum plant.
