Round 1: and Author Response The authors present a dataset where they have characterised the relative abundance of components of the photosynthetic electron transfer chain and related this to the measured rate of electron transfer from PSII.
The data are interesting and worth publishing but… (1) I don’t understand how they calculated the protein molar ratios. In the methodology section we learn that they extracted the crude proteins and then performed western analyses using specific antibodies, followed by image analyses. I don’t understand how they converted the western data to read the amount of specific proteins, in fmol, in the various organisms as shown in Figure 2; and used for the calculations in the rest of the paper. (Why are the units provided again in Line 220?). Please provide the reader with the methodology used for the quantification.
