【 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 F₁-ATPases and F₁-depleted submitochondrial particles (SMP), ATPases reconstituted from F₁-depleted pollen SMP showed the higher activity regardless of the source of F₁-ATPase. Fatty acid compositions of phospholipids in SMP were also different between bulbs and pollen. These suggest that the F₀ portion and/or its environment are important for regulation of F₀F₁-ATPase activity in L. longiflorum plant.
