Immunoblot analysis of photosynthetic subunit accumulation. (a): immunoblot analysis performed on WT and transformed lines proteins extract using specific antibodies for RUBISCO, ATPase β-subunit, PsaA, CP43, Cyt f, LHCII, CP29 and LHCBM4/6/8 subunits. Micrograms of chlorophylls loaded in each lane are reported on the top. (b): Immunoblot signals reported in panel A were analyzed by densitometry to determine the relative protein abundance. Each protein level was normalized to the WT protein level. LHCII/PSII and PSI/PSII ratio are also reported. Standard deviation is indicated as error bars (n = 4).
