Electron transfer from all respiratory chain dehydrogenases of the electron transport chain (ETC) converges at the level of the quinone (Q) pool. The Q redox state is thus a function of electron input (reduction) and output (oxidation) and closely reflects

We present a protocol for analyzing and evaluating the relocalization of proteins from the plasma membrane to chloroplasts. Some plant membrane-bound proteins carry dual targeting signals, e.g., a membrane-anchoring N-myristoylation motif and a chloroplast transit peptide. These proteins are predominantly
