Abstract
In intact spinach chloroplasts cytochrome b563 and cytochrome f show an antagonistic redox behaviour in the extent and kinetics of light/dark-induced absorbance changes. The extent of cytochrome b563 photoreduction appears to be influenced by the redox state of plastoquinone suggesting a regulation of cyclic electron flow at this level. Far-red illumination induces a membrane state with altered redox reactions of both cytochromes at a more oxidized level.
摘要
在完整的菠菜叶绿体中，细胞色素b563和细胞色素f在光/暗诱导的吸光度变化的程度和动力学方面表现出拮抗的氧化还原行为。细胞色素b563光还原的程度似乎受质体醌氧化还原状态的影响，这表明在此水平上对循环电子流存在调节作用。远红光照射诱导出一种膜状态，在这种状态下两种细胞色素的氧化还原反应在更高的氧化水平上发生改变。
