植物的基粒类囊体是由叶绿体中的多层紧密贴附的类囊体膜组成，它大大增加了叶绿体的面积与体积比，显著提高了叶绿体捕获光的能力，基粒层通过包埋在基粒膜中的蛋白质的基质表面堆叠和相互作用，主要是光系统（PS）Ⅱ组分，包括核心复合物、次要的捕光复合物其中，LHCII是地球上最丰富的膜蛋白，约占植物类囊体总蛋白的1/3，在基粒堆积过程中起着重要作用。
Dear Editor, Grana thylakoids in plants comprise multiple,tightly appressed thylakoid membranes in the chloroplast,which greatly increase the area-to-volume ratio and significantly improve the ability of chloroplasts to capture light.Grana layers are stacked and interact through the stromal surface of proteins embedded in the grana membranes,mainly photo-system (PS) Ⅱ components,including the core complexes,the minor light-harvesting complexes (Lhcb4,b5,and b6) as well as the major light-harvesting complex (LHClI).Among them,LHCII,which is the most abundant membrane protein on Earth and accounts for approximately one-third of the total protein in plant thylakoids,is reported to play an essential role in grana stacking.
