Studies on molecular physiological mechanism of plastid and mitochondrial division machineries

几乎所有的生物都依靠叶绿体（质体）的光合作用，叶绿体通过分裂增殖。在叶绿体分裂过程中，FtsZ环（位于基质中）、PD环（位于细胞质中）和dynamin环（位于细胞质中）依次形成，称为动态三重奏。PD环是PD机器的主要结构，看起来是一束直径约5- 7nm的细丝。动态三重奏用于线粒体分裂。分子生物学和生理生物学解决了包括动态三人组在内的分裂机制。

Almost all organisms depend on photosynthesis by chloroplasts (plastid), which proliferate by division. During chloroplast division, the FtsZ ring (localised in the stroma), the PD ring (in the cytoplasm), and the dynamin ring (in the cytoplasm) are formed in that order and called the dynamic trio. The PD ring is the main structure of the PD machinery and appears to be a bundle of fine filaments about 5-7 nm in diameter. The dynamic trio is used for mitochondrial division. The division machineries including the dynamic trio were solved by molecular and physiological biology.
