植物的光合膜(类囊体膜)是自然界中发现最广泛的生物细胞膜系统之一。它拥有光合作用装置，这对地球上的生命是必不可少的，因为二氧化碳是固定的，大气中的氧气是通过光合作用释放的。不同亚细胞室的脂类生物合成酶参与类囊体膜系统的生物发生。这一过程需要在叶绿体和内质网(ER)之间进行广泛的脂质前体交换。潜在的脂类转运现象在机制水平上尚不清楚，但模式植物拟南芥(Arobidopsis Thaliona)的遗传突变体最近已经出现，这些突变体破坏了内质网和叶绿体之间的脂类转运。他们的研究导致了内叶绿体被膜上的脂类转移机制的成分的确定。
The photosynthetic (thylakoid) membrane of plants is one of the most extensive biological cell membrane systems found in Nature. it harbours the photosynthetic apparatus, which is essential to life on Earth as carbon dioxide is fixed and atmospheric oxygen released by photosynthesis. Lipid biosynthetic enzymes of different subcellular compartments participate in the biogenesis of the thylakoid membrane system. This process requires the extensive exchange of lipid precursors between the chloroplast and the ER (endoplasmic reticulum). The underlying lipid trafficking phenomena are not yet understood at the mechanistic level, but genetic mutants of the model plant Arobidopsis thaliona with disruptions in lipid trafficking between the ER and the chloroplast have recently become available. Their study has led to the identification of components of the lipid transfer machinery at the inner chloroplast envelope.
