线粒体是一种双膜细胞器，可以动态地四处移动并改变其形状。在植物中，外膜的动力学还不太清楚。我们最近证明，线粒体外膜的管状突起很少或没有基质，称为MOPs（线粒体外膜突起; MOPs）。在这里，我们发现MOP可以在拟南芥的两个线粒体之间形成一个桥，这个桥似乎不涉及内膜。实时成像显示MOP桥的拉伸，证明了外膜的柔韧性。线粒体经常发生分裂和融合。这些观察结果提出了MOPs桥在这些过程中发挥作用的可能性。
Mitochondria are double-membrane organelles that move around and change their shapes dynamically. In plants, the dynamics of the outer membrane is not well understood. We recently demonstrated that mitochondria had tubular protrusions of the outer membrane with little or no matrix, called MOPs (mitochondrial outer-membrane protrusions; MOPs). Here we show that a MOP can form a bridge between two mitochondria inArabidopsis thaliana.The bridge does not appear to involve the inner membranes. Live imaging revealed stretching of the MOP bridge, demonstrating the flexibility of the outer membrane. Mitochondria frequently undergo fission and fusion. These observations raise the possibility that MOPs bridges have a role in these processes.
