We thank the reviewer for drawing this study to our attention. We have added a paragraph to the discussion to compare and contrast the Sukenik work with that presented here. The Sukenik data support a strong positive correlation between 1/tau and the RUBISCO to PSU ratio over a series of growth irradiances. While we also see a strong positive correlation between 1/tau and RUBISCO to PSII our results differ as the molar ratios of the components of the PSU differ significantly between the strains analyzed in the current work. This allows us to pinpoint the relationship of PSII to RUBISCO rather than other subunits of the PSU as the determinant of electron transport rate.
The approach and methods are robust and the ability to quantify components of the photosynthetic electron transfer chain is powerful.
