Answer to Reviewer 1.
Dear Reviewer 1!
Thank you for your trouble in reading the manuscript and for the comments you made to improve it. We have tried to take them into account and make appropriate changes in the draft.
Here are our responses:
- Line 35. What is Gloeomargarita [ ]?
Superfluous unnecessary parenthesis deleted.
`In the Introduction, the novelty of this draft should be emphasized.
In the Introduction we have now outlined the goals of our review as follows:
“The purpose of this review was to summarize and consider all known cases of phycobiliprotein antennae in relation to the evolutionary origin of different groups of oxygenic photosynthetics. We also outline possible reasons why phycobiliproteins are absent in terrestrial plants and many groups of algae.”
- Attention should be paid to the layout of draft, such as line 221 and 252-255.
The subtitle on line 221 is rewritten as: Chlorophyll f containing cyanobacteria and their involvement in the process of photoacclimation to far red light
The original phrase on lines 252-255 was:
To summarize somewhat, we can state that changes in the composition of phycobilproteins occur differently in cyanobacteria possessing Chls b, d, or f biosynthesis. There is complete loss of PBSs and phycobiliproteins, a reduction from whole PBS to phycobiliprotein cylinders, or only a partial rearrangement of the PBS core and replacement of individual phycobiliproteins in the lateral cylinders.
It is rewritten as:
To summarize somewhat, it is stated that changes in the composition of phycobiliproteins occur differently in cyanobacteria possessing various kinds of Chl pigments. There is complete loss of PBSs and phycobiliproteins in Chl b-containg phototrophs, a reduction from whole PBS to phycobiliprotein cylinders in Chl d-containing species and only a partial rearrangement of the PBS core and replacement of individual phycobiliproteins in Chl f-containing cyanobacterial cells.
Besides, we have improved the text for English language according to comments of Ref’s 2 and 3.

Reviewer 2 Report
The manuscript is scientifically sound. It has potentially high interest to readers interested in the area of antimicrobial resistance. I would suggest that the authors consider the following point as they revise their manuscript.
1. English changes required.

Answer to Reviewer 2
Dear Reviewer 2!
Thank you for your trouble in reading the manuscript and for positive evaluation of our work.
We have improved the text for English language according to your comment and analogous recommendations of Ref. 3.
Reviewer 3 Report
In this manuscript the authors conducted a major literature review to consider the features of PBS-68 antenna in the listed groups of photosynthetics. I consider that it is a very good document, it is very well written and presented, it presents valuable information and it has a common thread that allows us to understand the content of the document very well. It is a very valuable manuscript with great contributions to knowledge. I made small contributions directly on the pdf that can help improve the content, I mainly suggest including several references and more updated ones, also including a chapter of conclusions. The manuscript is very good and can be published.

The ground is made lighter.
Line 61. references
References are added.
Line 62. Match this paragraph with the previous one.
The paragraph is matched.
Line 65. references
Reference is added.
Line 69. The problem or gap in knowledge that this review aims to solve should be clearer
We have added two clarifying the problem phrases:
The purpose of this review was to summarize and consider all known cases of phycobiliprotein antennae in relation to the evolutionary origin of different groups of oxygenic photosynthetics. We also outline possible reasons why phycobiliproteins are absent in terrestrial plants and many groups of algae.

Line 620. Include a brief explanation
Brief explanation is included:
The slime polysaccharides, pectins, and the thin cell envelope which constitute protection of cyanobacteria contain a much lower proportion of carbon than cellulose as the basis of the eukaryotic cells wall.
