I am a confused how the photosynQ documentation and other publications that define the gH+ and vH+ measurements.

What does the MultispeQ Measure and how to cite sections of the photosynQ documentation define vH+ and gH+ as proton conductivity and steady state proton flux, respectively.

However, Avenson et al. (2005) defines vH+ as the steady-state rate of photon flux, and Kanazawa and Kramer (2002) defines gH+ as proton conductivity. Does the photosynQ documentation have the definitions of vH+ and gH+ transposed?

AVENSON, T.J. et al., 2005. Integrating the proton circuit into photosynthesis: progress and challenges. Plant, Cell and Environment, 28(1), pp.97–109. Available at: http://dx.doi.org/10.1111/j.1365-3040.2005.01294.x.

Kanazawa, A. & Kramer, D.M., 2002. In vivo modulation of nonphotochemical exciton quenching (NPQ) by regulation of the chloroplast ATP synthase. Proceedings of the National Academy of Sciences, 99(20), pp.12789–12794. Available at: http://dx.doi.org/10.1073/pnas.182427499.

Hi Craig, You found a typo in the Parameter section. Yes, gH+ is the proton conductivity, and vH+ is the flux. We will fix it. Thank you for pointing out. Atsuko

Thank you.

We have notified the web developer. It will be updated on coming week. FYI, Atsuko

It looks like they already made the correction.
