(Please upload your review as an attachment if it exceeds 20,000 characters) Reviewer #1: The chloroplast proteome is encoded by both nuclear genome and its own genome, which play critical roles in plant photosynthesis, metabolism and other biological processes. In recent years, characterization of chloroplast proteome changes under environmental stress condition has attracted the attention of the plant biologists. Correspondingly, the topic of this manuscript is of interest. The work seems to be well done and the results carefully described. Overall, the figures and descriptions are good. However, there are several major problems and many mistakes. I do not find this manuscript publication-ready at this stage for the following reasons: Major concerns [1] A major drawback of this study is the purity of the chloroplast fraction. On what basis the authors made the statement “…...that our chloroplast isolation and enrichment strategy was effective in reducing the number of cross-contaminants…...” (Results and Discussion: Line 259-262; Final Remark: Line 679-682). Use of NSAF approach for determining organelle abundance typically rely on detection of a very few marker proteins, and hence is unsatisfactory. In my opinion, there should be a few more more wet-lab experiments that would justify the findings of proteomics analysis. The authors should pick up a few candidates and examine their translocation the chloroplasts, say by transient expression analysis. [2] The manuscript describes some interesting aspects of biochemistry operating in chloroplast proteome. The authors’ preparation of chloroplast yields a considerable number of unexpected proteins, which are classically considered to be translocated to other cellular compartments. Since contamination from other organelles cannot be discounted, the information obtained for the unexpected proteins in the fraction remains highly suspected. The authors should consider revising the manuscript by focusing on chloroplast proteins, and reducing the description and discussion of the unexpected proteins to a minimum. [3] The authors stated, in the abstract, that “This study contributes to a more comprehensive understanding on the subcellular mechanisms that lead to plant leaf adaptation and ultimately to Eucalyptus grandis productivity”. There is a need to revisit the statement because it is not convincing in the case of Eucalyptus grandis productivity. [4] Eucalyptus leaves are a great source of antioxidants, particularly flavonoids, which are effective in protection against oxidative stress and ROS damage. I didn’t find any mention of this sort in the manuscript. Instead, the first two paragraphs of the Introduction contain too much general information which are text book materials. I feel that these paragraphs can be clubbed and restructured. Noticeably, I have counted as many as 41 references in the Introduction, many of which describe the general aspects of chloroplast biogenesis and the function of chloroplast in plant. The number of references in this section should be reduced. [5] “…… 50 μg of proteins were separated for 1 hour by denaturing electrophoresis on a polyacrylamide gel containing sodium dodecyl sulfate (SDS-PAGE) to obtain a single band”. What is the meaning of “to obtain a single band”? [6] In general, experimental protein localization requires a great deal of time and resources, which are bypassed by prediction analysis. It is recommended that the prediction analysis be accomplished by a series of prediction tools for cross-validation test. In this study, subcellular localization of the proteins was predicted by ChloroP and Predotar. Why don’t add some other tools, for example, BaCelLo, WoLF PSORT, TargetP etc. Minor concerns Authors should ensure the text is polished enough to be published. The English needs to be much improved and the authors should request the assistance of a professional service. While the entire text requires revision, I will cite some issues that should be addressed to avoid errors and misinterpretations. Please note that the revision should not be limited to the following items: [1] Please carefully edited the manuscript; remove most acronyms unless very much necessary. [2] “…...may contribute to enlarge the understanding…...” (Abstract) is not a good read. Similarly, “…… proteome analysis of the Eucalyptus grandis chloroplast proteome….”. These should be suitably rephrased. [3] There must be a space between the numerical value and unit symbol; missing at so many places in the text. [4] “Eucalyptus grandis were planted” is more appropriate than “Eucalyptus grandis plants were cultivated” (Materials and Methods: Line 108). [5] The sentence “For both assays using leaf sampling, plant material………chloroplasts, as described in the next sections” (Line 124-125) is absolutely unnecessary. [6] Rephrase the sentence “Fluorescence analysis was performed on the fluorometer FluorPen FP …………” (Line 130-132). [7] “Aliquots of six grams of leaves...” is imperfect in the sentence (Line 143-144). [8] “……seems prone to catabolic and redox processes as leaves age….” (Line 683-684) doesn’t make sense. [9] Fig. S2 legend: Which one is correct: chlorophyll relative quantification (CCI) or chlorophyll content index (CCI)? [10] “up-regulated” and “down-regulated” can be replaced with “upregulated” and “downregulated”, respectively throughout the text. [11] References need extensive corrections since the references are not in the same format [as per the style of PLoS ONE], particularly the journal names (Reference 33: Environ. Sci. Pollut. Res.; Reference 33: J Exp Bot.). Reviewer #2: The manuscript describes proteomics changes in chloroplast organelle of Eucalyptus grandis during development and in seasonal changes. I found it very interesting since it adds a brick into the wall of knowledge of plant metabolism changes in physiological conditions providing useful information on functional networks at the basis of development process. Further, it is well known that chloroplast plays a central role in plant metabolism and thus in adaptation to environmental changes, thus investigation of plastid proteome may help in understanding plant adaptation mechanisms that can be exploited to increase plant productivity. Overall, the manuscript is clear, however, I have some suggestions. I have some concern on the possibility to excise a single band from an SDS-PAGE gel where 50 ug of proteins have been loaded. Often, using a 2D-PAGE overlapping of bands occurs. I invite the authors to be consistent with Figs and Tables’ nomenclature (e.g., 2S vs S2) Figure S2B is a duplication of S1A In all the text many words are collapsed with spaces missing (e.g., L59, 64, 70…304, 351, 518, 527, 550 etc) L341-63 and 440-53, please, insert the full protein name (as authors do in L413-419) L352 and 451 “PRPL1” is a typo? L424-425 this sentence is not clear L413-19 and 433-37 short name of proteins should be near their full name Please, pay attention to typos (e.g., L580 “the” is duplicated, “fakk” should be “fall”) ********** 6.

(Please upload your review as an attachment if it exceeds 20,000 characters) Reviewer #1: Compared to the original manuscript, the revised version has been greatly improved, especially with respect to structural rearrangement and copyediting. The authors addressed most of the reviewers' questions and comments. Yet I have few concerns which are listed below: [1]. I would prefer a modified title “The Eucalyptus grandis chloroplast proteome: seasonal variations in leaf development” and over “The Eucalyptus grandis chloroplast proteome: leaf development and seasonal variations over”. [2]. The last line in the abstract “Mass spectrometric data are available via ProteomeXchange under identifier PXD029004” can be moved to “Results and Discussion” section. [3]. “Transient seasons” in the subtitle “Transient seasons induce the most pronounced chloroplast proteome changes” is not a good read and should be modified. [4]. The phrase “Proteome isolation” is not appropriate and hence the subtitles “Chloroplast proteome isolation” and “Total leaf proteome isolation” should be modified. [5]. Subtitle “Final Remarks” can be replaced with “Conclusions”. Reviewer #3: After going through the revised MS and the replies to the reviewer's queries, I believe that the MS has already been critically evaluated by the previous reviewers and that pertinent questions were asked by the reviewers. In response to their queries, the authors have addressed all the concerns adequately which has significantly improved the scientific merit of the article. Based on these observations, I believe that the MS can be accepted in its current form. ********** 7.
