Thank you the good suggestion, however, the markers for each variables including the control treatment were generated automatically by the graph making software used.

Reviewer 2 Report

Comments of mine are the same as those found in the attachment that I sent as well. Same for the Editors and the Authors, no secret. Briefly: I'll endorse and suggest from my side for publication - with minor corrections. But insist on 3 corrections. (1) INTRODUCTION: please correct the wrong and irritating interpretation of Ref [10]. The TOXINS which kill the insect, and are produced PRIOR TO killing the insects, and a few molecules of which is enough to kill the insect, are NOT ANTIBIOTICS. Antibiotics (antimicrobial peptides, non-ribosomal templated or biosynthesized NR-AMPs)) are produced only by the phase 1 EPBs and are produced throughout life by them. 2. MATERIALS AND METHODS: please give the strain names of the bacterium species name, it is especially essential for the Photorhabdus luminescens, since this species has been comprised of three physiologically, genetically, and biochemically different subspecies: P.l. ssp. luminescens, P.l. laumondii, and P.l. akhurstii. (3) IMPROVE ENGLISH, by correcting the whole paper with the help of GRAMMARLY. I made it with their otherwise excellent ABSTRACT and in the above-mentioned attachment file. I suggest accepting after the suggested minor corrections.

Reviewer 2

This is a high-standard quality publication-candidate paper with invaluable useful results of the
research field, which I intend to endorse and suggest for publication. I have only three little irritating but curable things that I suggest to take into your consideration before submitting the final draft:
1. INTRODUCTION: Ref. 10 is incorrectly interpreted in the INTRODUCTION. The EPB cells
in the gut of the IJ are in the primary phase (10), therefore they produce antimicrobials
(antibiotics), AMPs) are produced NOT only „PRIOR TO” killing the insects but throughout
their life. But EPB-s - both the primary(10), and secondary-phase (20) phase ones produce
INSECT KILLING TOXINS, which are NOT ANTIBIOTICS, which are PROTEINS
(polypeptides) and a few molecules of which are enough to kill the insect. So please DO NOT
mix antibiotics with toxins, because such an irritating misleading sentence may reduce the
scientific quality of your paper providing the false impression that the authors do not familiar
with the system. But this small thing can easily to corrected.

Response:

Thank you for your careful review. We have generally revised the paragraph as suggested for better understanding.

 

MATERIALS AND METHODS: I miss the used Photorhabdus luninescens strain
names and Xenorhabdus nematophila species. Please add them. It is especially important in
the case of Photorhabdus luminescens because this species is comprised of 3 physiologically
and biochemically rather different subspecies, P.l. luminssecens, P.l, laumondii, and P.l.
akhurstii

 

Response:

The strain/subspecies names corrected as provided the author who supplied us with the nematode samples used in our experiment. The name was generally used throughout the manuscript. Some of their references include;

Qiu, X., Yan, X., Liu, M., & Han, R. (2012). Genetic and proteomic characterization of rpoB mutations and their effect on nematicidal activity in Photorhabdus luminescens LN2.

 

The English should be moderately improved, for instance, by using Grammarly. In order to
help with the correction to the authors, I went through your (otherwise) excellent Abstract and
present it here for their service.

Response:

The manuscript have been checked and revised by a native English-speaking colleague.

Your comments and careful review have been found very helpful in improving our manuscript. Thank you so much.
