Plastoquinone (PQ) is a terpenoid-quinone (meroterpenoid) molecule involved in the electron transport chain in the light-dependent reactions of photosynthesis. The most common form of plastoquinone, known as PQ-A or PQ-9, is a 2,3-dimethyl-1,4-benzoquinone molecule with a side chain of nine isoprenyl units.

质体醌（英語： Plastoquinone ，简称：PQ）是一种醌分子，与光合作用中光反应的电子传递链有关。 质体醌被还原（得到叶绿体基质中的两个 质子 （H + ），并与来自 光系统 II 的两个电子（e - ）相结合），形成质体酚。

Dec 16, 2016 · Plastoquinone (PQ) and ubiquinone (UQ) are two important prenylquinones, functioning as electron transporters in the electron transport chain of oxygenic photosynthesis and the aerobic respiratory chain, respectively, and play indispensable roles in plant growth and development through participating …

植物体中有几种pq，它们的区别是 异戊二烯 单位数目不同。 叶绿体 中最多的是pq9。 在光合链中，既可传递电子，又可传递质子，其 氧化还原反应 ：氧化还原电位约为0.1伏。 氧化型的pq从 类囊体 膜的靠外一侧接受电子，并与膜外质子结合，尔后向内扩散，在膜内侧被 细胞色素f 氧化，交 …

Dec 1, 2020 · Plastoquinone-9 (PQ-9) is an essential component of photosynthesis that carries electrons in the linear and alternative electron transport chains, and is also a redox sensor that regulates state transitions and gene expression.

Plastoquinone (PLQ) acts as an electron carrier between photosystem II (PSII) and the cytochrome b6f complex. To understand how PLQ enters and leaves PSII, here we show results of coarse grained molecular dynamics simulations of PSII embedded in the ...

该研究发现，植物在响应光照变弱时引起的 质体醌 PQ（plastoquinone）氧化可以抑制气孔发育，并揭示PQ氧化是通过一条非EPF-受体-MAPK的新信号通路调控了气孔发育的抑制。
