Reviewer's Responses to Questions

Comments to the Authors:

Please note here if the review is uploaded as an attachment.

Reviewer #1: In their manuscript, “Network feature-based phenotyping of leaf venation robustly reconstructs the latent space”, Iwamasa and Noshita present an analysis pipeline, from image acquisition to graph-based analysis techniques, to morphometrically analyze leaf venation in five angiosperm species.

I very much enjoyed this manuscript and I believe that these approaches are needed in the leaf venation community. As the authors state, the current state-of-the-art is mostly focused on applying statistics to simple parametric measurements (like length, width, numbers of loops, etc) and the use of CNNs and other modern approaches are desperately needed for segmentation. This manuscript addresses all these issues together and I believe it will have a big impact.

My biggest criticism: zenodo links to the github and the data repositories were redacted in the manuscript and I was not able to evaluate the code. This is going to be the most impactful element of this work, and I hope that the fully reproducible workflow, using the cleared leaf database and U-NET for image segmentation especially, is provided upon publication.

Some overall thoughts:

-It was good to see a truthful analysis of the underestimation of edges and nodes in non-chemically treated leaves. This is to be expected, and the method is powerful because it can make use of the public cleared leaf dataset and apply to backlit photos!

-The graph-based analysis is refreshing to see. The paper focuses on the latent space, and example venation images are shown for datapoints in the PCA space. Do the authors think they could somehow derive meaningful eigen-representations of venation networks?

-Related to the above, I wonder if a discussion of other graph-based analysis approaches, like vector representations through node embeddings or graph distances based on the segmented network could be incorporated. Deriving biological meaning from these powerful mathematical representations of graphs will be interesting to look at as more venation networks are analyzed.

I enjoyed this manuscript a lot, great job!

**********

Have the authors made all data and (if applicable) computational code underlying the findings in their manuscript fully available?

The PLOS Data policy requires authors to make all data and code 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 and code 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 or code —e.g. participant privacy or use of data from a third party—those must be specified.

Reviewer #1: No: I am assuming the github and data repositories will be made publicly available, but the zenodo links were redacted in the manuscript I reviewed

Reviewer #2: No:

Reviewer's Responses to Questions

Comments to the Authors:

Please note here if the review is uploaded as an attachment.

Reviewer #1: The authors have addressed all of my concerns, and the final published manuscript should contain a publicly available github link to the code.

Reviewer #2: The authors have addressed my comments in a satisfactory manner.

Now, I can clearly understand the contents and claims especially those in Fig. 7B and C.

Here are some thoughts after reading the revised version. These are very minor comments.

・L33 a functional trade-off between what and what might be vague by the first reading.

・L278:"loopiness (i.e., the frequency of looping structures, ...)" spatial scale for the frequency might be vague by the first reading.
