Similar results were obtained by other authors before:
- Hagen C, Braune W, Birckner E, Nüske J (1993) Functional aspects of secondary carotenoids in Haematococcus lacustris [Girod] Rostafinski (Volvocales). I. The accumulation period as an active metabolic process. New Phytol. 125: 625–633; Abstract: Alterations of photosynthetic activity were investigated during accumulation of secondary carotenoids in Haematococcus lacustris (Girod) Rostafinski. Using several methods regarding (i) pigment pattern and pigment content (cytophotometry, computer-aided microscopic image analysis, in vivo absorption spectroscopy, highperformance liquid chromatography) and (ii) photosynthesis (microfluorometry, modulated chlorophyll fluorescence and luminescence detection, O2 evolution and consumption measurement, 77 K fluorescence spectroscopy) we examined single cells and cell suspensions of the green alga. The results indicate decrease of both the photosystem II activity and the linear electron transport accompanying synthesis of secondary carotenoids. On the other hand, activation of those processes leading to an increased transthylakoid proton gradient could be established during early accumulation period. This is assumed to be an active adaptation of the photosynthetic apparatus to energetic requirements given by secondary carotenoid biosynthesis in H. lacustris. (Haematococcus pluvialis Flotow is synonym to H. lacustris [Girod] Rostfinski and is, at present, the correct name)

It is always nice to hear from a research fellow in the same area! Thanks for your valuable comment on the recently published paper. Considering those work you have done were quite systematic and comprehensive, we felt very much sorry that not all of your work were cited in our paper. During the preparation of the manuscript, we read the fulltext of two of your papers, the one published in 2002 (European Journal of Phycology) and the other published in 1994 (Journal of Phycology). However, one of the three anonymous reviewers proposed that some references in our manuscript were outdated. We thought it might be better to cite some recently published paper. Thus, only the one publishe in 2002 by C. Hagen and colleagues was cited. Besides, we found the name of the species was termed as “Haematococcus lacustris” instead of “Haematococcus pluvialis”. Obviously, this should not be an issue. However, most recently published papers preferred to use “H. pluvialis”. As for Ita Zlotnik et al‘s work, from the abstract content we found the cyst cell was induced under nitrogen starvation. Besides, we did not have access to the fulltext of this reference as well. Of course, several references like the one by Blum et al (Electrophoresis, 1987) and Chua et al (PNAS, 1975) were quite classic technical paper, though seemed outdated, were unavoidable in the reference.
Again, we are quite glad to hear from you.
Thanks again for your comment.
Best regards!
