FIGURE 3.

Immunoblots of representative PSI and PSII proteins in the wild type, nfu2 and nfu3 single mutants and sesquimutants. (a) Immunoblots of PSI reactive‐center proteins PsaA, PsaB, and PsaC, and PSI‐associated light‐harvesting complex I proteins LHCA2 and LHCA4. (b) Immunoblots of PSII reaction‐center proteins D1, CP43, and CP47 and PSII‐associated light‐harvesting complex II proteins LHCB2 and LHCB4. Thylakoid membrane proteins were used in (a‐b) and were loaded on an equal fresh tissue weight basis. Symbol ++++ indicates that the protein binds to 4Fe‐4S clusters. Five‐week‐old plants were used for SDS‐PAGE and immunoblot analysis in this figure
