光合链

抑制光合链型除草剂的快速生物检定研究

Rapid Bioassay of Herbicides Inhibiting Photosynthetic Chain

拟南芥体内含铜离子最丰富的蛋白质是位于内囊体腔中的质体蓝素（PC），它是光合电子传递链所必需的蛋白。

The most abundant copper containing protein plastocyanin ( PC ) is required for photosynthetic electron transport within the thylakoid lumen .

利用人工电子供、受体和已知的专一性抑制剂，研究了2-庚基，4-羟喹啉-N-氧化物（HOQNO）在菠菜叶绿体光合电子传递链上的抑制部位。

The site of action of 2-heptyl-4-hydroxyquinoline-N-oxide on the electron transport chain of isolated spinach chloroplasts was studied with the aid of artificial donors or acceptors and known specific inhibitors .

初春随着温度的回升，捕光天线系统、光合电子链的活性、光合速率逐渐恢复。

Consequently , activity of light-harvesting antenna system as well as that of photosynthetic chain and photosynthetic rate recovered gradually as air temperature rising in early spring .
