Schematic diagram of the thylakoid membrane-localized photosynthetic and respiratory electron transport chains in PSI-less/ScpABCDE⁻ in the absence (a) or presence (b) of NaCl. Lines indicate the electron transport, filled lines indicate sustained electron transfer, and dotted lines indicate poor electron transfer. Cox, cytochrome c oxidase; Cyd, bd quinol oxidases; Cyt c ₆, cytochrome c ₆; PC, plastocyanin; PQ, plastoquinone; PQH₂, plastoquinol; OEC, oxygen evolving complex; PSII, photosystem II
