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: This manuscript shows Tomatoes produced using both the conventional and organic fertilizer maintained similar yield and quality through uncontrolled green peach aphid infestation, by maintaining biochemical properties and transcriptional shift towards catabolic processes. This study is significant as it extensively assesses the interaction between aphid infestation and organic systems to provide insights on developing improved pest management strategies and identifying targets for crop improvement. The study is well designed and comprehensive as authors compared tomato plants grown in organic or conventional fertilizer with or without aphid infestation and used leaf and fruit tissues for biochemical and transcriptomic profiling. While the manuscript looks technically sound and the data provided supports the conclusion, I have following comments and suggestions to improve the manuscript:

1. Authors stated significantly lower nitrogen content resulting in the lower amino acid availability in the phloem maybe be the limiting factor for aphids in the plants grown in organic fertilizer and supported it with the literature (Mattson WJ 1980 Annu Rev Ecol Systm). I would suggest authors to add more reports to the discussion section on the role of nitrogen and amino acids in aphid infestation of plants.

2. In addition to nutrient and plant defense responses, I would recommend authors to discuss the role of soil microbiome in aphid-plant interactions in organic vs conventional farming practices and provide relevant references.

3. Authors tested the effect of aphid infestation on the yield of tomato plants in conventional vs organic fertilizer (Table 1). I would suggest author to add more information to the material and method sections Line 117 on growth stage of aphids added/counted, timepoint and method of counting.

4. Authors should add more information to the table and figure legends like number of plants (N) and type of statistical method used.

5. The quality of images is very poor in Figure 1 and Figure 2 of the manuscript PDF file and it’s hard to understand the axis labels. This may have been caused during file conversion, as the attached PNG images look good. I would suggest authors to check this and see if they can improve the image quality.

6. Line 232: I would suggest authors to edit the sentence to make it clear that Cluster dendogram for leaf and fruit are shown in Figure1 and Figure 2 respectively.

7. Line 234: Same as line 232, authors should make it clear that correlation plots in the gene co-expression network for leaf and fruit samples are shown in Figure 3 and Figure 4 respectively.

Reviewer #2: 1. The manuscript would benefit from clearer reporting of the statistical framework used for trait comparisons. Please specify the exact model structure (e.g., two-way ANOVA with fertilizer and aphid treatment as fixed effects), confirm whether interaction terms were tested throughout, and indicate how assumptions (normality, homoscedasticity) were evaluated. Where feasible, reporting exact p-values and degrees of freedom (possibly in supplementary material) would improve transparency.

2. Several figure captions, particularly for module–trait correlation heatmaps and GO enrichment analyses, lack sufficient detail to be interpreted independently. Please clarify color scales, significance thresholds, and whether GO enrichment results are corrected for multiple testing. Additionally, terminology such as “organic fertilizer treatment,” “organic production,” and “organic growing system” is used interchangeably throughout the manuscript; standardizing this language would improve clarity.

Revision 1

Point-by-point response to reviewer’s comments:

Please note: Line numbers correspond to the Track Changes version of the manuscript.

Reviewer #1: This manuscript shows Tomatoes produced using both the conventional and organic fertilizer maintained similar yield and quality through uncontrolled green peach aphid infestation, by maintaining biochemical properties and transcriptional shift towards catabolic processes. This study is significant as it extensively assesses the interaction between aphid infestation and organic systems to provide insights on developing improved pest management strategies and identifying targets for crop improvement. The study is well designed and comprehensive as authors compared tomato plants grown in organic or conventional fertilizer with or without aphid infestation and used leaf and fruit tissues for biochemical and transcriptomic profiling. While the manuscript looks technically sound and the data provided supports the conclusion, I have following comments and suggestions to improve the manuscript:

1. Authors stated significantly lower nitrogen content resulting in the lower amino acid availability in the phloem maybe be the limiting factor for aphids in the plants grown in organic fertilizer and supported it with the literature (Mattson WJ 1980 Annu Rev Ecol Systm). I would suggest authors to add more reports to the discussion section on the role of nitrogen and amino acids in aphid infestation of plants.

Response: As suggested, discussion of the relationship between plant nitrogen status and aphid feeding success has been expanded upon and the corresponding paragraph has been modified. Additional references have also been added. See lines 357-368.

2. In addition to nutrient and plant defense responses, I would recommend authors to discuss the role of soil microbiome in aphid-plant interactions in organic vs conventional farming practices and provide relevant references.

Response: The authors agree that soil microbiome is an important aspect in plant response to stressors and works cooperatively with fertilization regime in modulating plant health. Mention of this has been added in the introduction, see lines 99-100. As no experimental work on soil microbiome was conducted in this study, extensive discussion would be beyond the scope of this work.

3. Authors tested the effect of aphid infestation on the yield of tomato plants in conventional vs organic fertilizer (Table 1). I would suggest author to add more information to the material and method sections Line 117 on growth stage of aphids added/counted, timepoint and method of counting.

Response: As per reviewer feedback, additional information on the growth stage of the aphids, their quantification, and the time of their quantification was added to the manuscript. See lines 124-126 and 128-131.

4. Authors should add more information to the table and figure legends like number of plants (N) and type of statistical method used.

Response: We have added more details to the table and figure legends regarding sample sizes and statistical analyses conducted. See lines 204-209; 221; 244-246; 249-253; 270-271; 273-274; 294-303; 320-323; 334-348; 380-384.

5. The quality of images is very poor in Figure 1 and Figure 2 of the manuscript PDF file and it’s hard to understand the axis labels. This may have been caused during file conversion, as the attached PNG images look good. I would suggest authors to check this and see if they can improve the image quality.

Response: The reviewer is correct. High resolution images have been submitted to the journal.

6. Line 232: I would suggest authors to edit the sentence to make it clear that Cluster dendogram for leaf and fruit are shown in Figure1 and Figure 2 respectively.

Response: Edited to clarify this in the text, in addition to the existing captions for Figures 1 and 2. See line 258.

7. Line 234: Same as line 232, authors should make it clear that correlation plots in the gene co-expression network for leaf and fruit samples are shown in Figure 3 and Figure 4 respectively.

Response: Edited this sentence as well, in addition to the existing captions for Figures 3 and 4. See lines 260.

Reviewer #2

1. The manuscript would benefit from clearer reporting of the statistical framework used for trait comparisons. Please specify the exact model structure (e.g., two-way ANOVA with fertilizer and aphid treatment as fixed effects), confirm whether interaction terms were tested throughout, and indicate how assumptions (normality, homoscedasticity) were evaluated. Where feasible, reporting exact p-values and degrees of freedom (possibly in supplementary material) would improve transparency.

Response: Please see the response to the other reviewer. Briefly, information on the statistical frameworks used for our analysis has been elaborated upon, as well as the specific software used to process the data and evaluate and transform the data in response to assumptions. Wherever log transformation was necessary, it has been clarified in the text. See lines 206 and 252. Overall additional details have been included in table and figure captions, as well. See lines 204-209; 221; 244-246; 249-253; 270-271; 273-274; 294-303; 320-323; 334-348; 380-384. Interaction terms were tested throughout, the results of which can be seen in Tables 1 and 2. Exact p-values to 4 digits for Tables 1 and 2 have been provided as a new supplementary material - Table S8.

2. Several figure captions, particularly for module–trait correlation heatmaps and GO enrichment analyses, lack sufficient detail to be interpreted independently. Please clarify color scales, significance thresholds, and whether GO enrichment results are corrected for multiple testing. Additionally, terminology such as “organic fertilizer treatment,” “organic production,” and “organic growing system” is used interchangeably throughout the manuscript; standardizing this language would improve clarity.

Response: Additional details have been added to figure captions to assist independent interpretation, See lines 204-209; 221; 244-246; 249-253; 270-271; 273-274; 294-303; 320-323; 334-348; 380-384.

Multiple testing was not conducted for GO enrichment results as the GO hierarchy violates the assumption of independence of tests. The statistical test used for this work has been clarified, see lines 219-221.

Differentiation between organic fertilization and organic fertilizer has been made throughout the manuscript to clarify the fact that this study only evaluates an organic input, rather than other aspects of organic production and fertilization. In the introduction, however, the term “organic production” is used more broadly since that section discusses organic production in a general context.
