PLOS ONE

Dear Dr. Zhou,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

Please submit your revised manuscript by Oct 25 2020 11:59PM. If you will need more time than this to complete your revisions, please reply to this message or contact the journal office at plosone@plos.org. When you're ready to submit your revision, log on to https://www.editorialmanager.com/pone/ and select the 'Submissions Needing Revision' folder to locate your manuscript file.

Please include the following items when submitting your revised manuscript:

  • A rebuttal letter that responds to each point raised by the academic editor and reviewer(s). You should upload this letter as a separate file labeled 'Response to Reviewers'.
  • A marked-up copy of your manuscript that highlights changes made to the original version. You should upload this as a separate file labeled 'Revised Manuscript with Track Changes'.
  • An unmarked version of your revised paper without tracked changes. You should upload this as a separate file labeled 'Manuscript'.

If you would like to make changes to your financial disclosure, please include your updated statement in your cover letter. Guidelines for resubmitting your figure files are available below the reviewer comments at the end of this letter.

If applicable, we recommend that you deposit your laboratory protocols in protocols.io to enhance the reproducibility of your results. Protocols.io assigns your protocol its own identifier (DOI) so that it can be cited independently in the future. For instructions see: http://journals.plos.org/plosone/s/submission-guidelines#loc-laboratory-protocols

We look forward to receiving your revised manuscript.

Kind regards,

Reviewer's Responses to Questions

Comments to the Author

1. Is the manuscript technically sound, and do the data support the conclusions?

The manuscript must describe a technically sound piece of scientific research with data that supports the conclusions. Experiments must have been conducted rigorously, with appropriate controls, replication, and sample sizes. The conclusions must be drawn appropriately based on the data presented.

The PLOS Data policy requires authors to make all data underlying the findings described in their manuscript fully available without restriction, with rare exception (please refer to the Data Availability Statement in the manuscript PDF file). The data should be provided as part of the manuscript or its supporting information, or deposited to a public repository. For example, in addition to summary statistics, the data points behind means, medians and variance measures should be available. If there are restrictions on publicly sharing data—e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: Yes

5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Study submitted by Zhou et al on "Rooting ability of rice seedlings increases with higher soluble sugar content from exposure to light" explains correlation between endogenous sugars with rooting ability under different light durations. In its present form, I feel authors fails to highlight the novelty of this study. During active growth phase most of the energy coming through respiration is utilised for growth process for example rooting in the early seedling establishment phase. This energy is certainly coming by the breakdown of simple sugars. Thus, it is very obvious to get a strong and positive correlation between rooting ability and endogenous sugars. Moreover, more light would increase amount of photo-assimilates until a saturation point. On the other hand, rooting ability is a complex trait which is tightly regulated by genetic background and genotype x environment interaction. Authors should discuss in more details, how increase in assimilates partitioned towards root. As roots could be main sink during early growth, traits such as leaf area, photosynthetic ability and root architecture may be crucial to determine overall rooting ability.

Reviewer #2: The research experiment was well executed with proper statistical support. The results were well presented and discussed with proper references. The comments of earlier reviewers were properly addressed and the same reflected in the MS. With this the MS entitled "Rooting ability of rice seedlings increases with higher soluble sugar content from exposure to light" can accepted for publication.

Reviewer #3: Overall this is a well written manuscript. However a minor improvement is required in the introduction section. Exposure to light is the main treatment of this manuscript but in the last paragraphs of introduction section only 1-2 general sentences have been added about the variation of soluble sugars in response to light exposure. I suggest add more specific literature in last paragraphs of the introduction section to justify the of selection of this treatment.

Revision 1

Response to Reviewer 1 Comments

Point 1: In its present form, I feel authors fails to highlight the novelty of this study. During active growth phase most of the energy coming through respiration is utilized for growth process for example rooting in the early seedling establishment phase. This energy is certainly coming by the breakdown of simple sugars. Thus, it is very obvious to get a strong and positive correlation between rooting ability and endogenous sugars. Moreover, more light would increase amount of photo-assimilates until a saturation point. On the other hand, rooting ability is a complex trait which is tightly regulated by genetic background and genotype x environment interaction. Authors should discuss in more details, how increase in assimilates partitioned towards root. As roots could be main sink during early growth, traits such as leaf area, photosynthetic ability and root architecture may be crucial to determine overall rooting ability

Response 1: Thank you very much for your professional and kind suggestions. We agree with your assessment, your suggestions have opened our mind and we have reorganized the discussion section of our article to highlight the novelty of our study. Based on the experimental data we got, we adjusted our discussion points to “the substances determining rooting ability in rice seedlings under light changed with the duration of light” and “soluble sugar content was more dominant in determining rooting ability compared with nitrate-nitrogen content”. Indeed, it is very obvious to get a strong and positive correlation between rooting ability and endogenous sugars. However, our results showed that it’s not so simple. Rooting ability is a complex trait, and our article demonstrated the influence of light on rooting ability and the complexity of the effect of light duration on rooting ability, and compared the relative importance of the effects of endogenous soluble sugar and nitrate nitrogen. Based on this, we put forward some suggestions that can guide the rice mechanical transplanting of rice.

Response to Reviewer 2 Comments

Point 1: The research experiment was well executed with proper statistical support. The results were well presented and discussed with proper references. The comments of earlier reviewers were properly addressed and the same reflected in the MS. With this the MS entitled "Rooting ability of rice seedlings increases with higher soluble sugar content from exposure to light" can accepted for publication.

Response 1: Thank you for your comments.

Response to Reviewer 3 Comments

Point 1: Overall this is a well written manuscript. However a minor improvement is required in the introduction section. Exposure to light is the main treatment of this manuscript but in the last paragraphs of introduction section only 1-2 general sentences have been added about the variation of soluble sugars in response to light exposure. I suggest add more specific literature in last paragraphs of the introduction section to justify the of selection of this treatment.

Response 1: Thank you very much for your professional and kind suggestions. We have made corresponding modifications according to your suggestions. In the introduction, we use a separate paragraph (line 74-83) to introduce the fluctuation of soluble sugar content in plants under light with detailed data.
