A large variation in apparent half-life was observed for the nucleusencoded
proteins of LHCII and LHCI. The decrease of these proteins
could be mediated through different mechanisms. It is well established
that inhibition of plastid protein synthesis in land plants induces retrograde
signaling with an inhibitory effect on the expression of nuclear genes involved in photosynthesis [24–26]. A similar retrograde signaling
pathway also operates in C. reinhardtii and affects a restricted set
of proteins including those of LHCII [8].
