Abstract
The precursors to LHCPII are large polyproteins containing multiple copies of LHCPII, and photocontrol of their formation is largely translational. Under conditions favoring LHCPII accumulation in the thylakoids, a reaction with anti-LHCPII antibody can be observed in the Golgi apparatus by immuno-electron microscopy. The timing of the immunoreaction in the Golgi apparatus in synchronous cells and in cells undergoing normal light-induced chloroplast development suggests that the nascent LHCPII passes through the Golgi on the way to the thylakoids. In addition, the same phenomenon has been reported not only for Euglena but also for dinoflagellate cells and the higher plants (2006). The phenomenon of the photosynthetic proteins synthesized in the cytoplasm goes through the Golgi is considered to be a common phenomenon observed in plant cells.
