Octoploids Show Enhanced Salt Tolerance through Chromosome Doubling in Switchgrass (Panicum virgatum L.)

Round 1

Reviewer 1 Report

Comments and Suggestions for Authors

The authors present a thorough overview of differences in cell response and transcriptomic differences in octoploid switchgrass versus the tetraploid progenitor. The methods are appropriate and the results clearly demonstrate and add to our knowledge of how polyploids might tolerate environmental stresses better and thus form new species or offshoots. 

I have one minor comment - in the methods, the authors state that two plants with basically similar growth status were selected from each treatment for measurement, but then say that three biological replicates were performed... surely they needed three plants per treatment for this to be the case?

Author Response

Thank you very much for taking the time to review this manuscript. And thank you for pointing this out. Two switchgrass plants mean octoploi and tetraploid switchgrass.  All measurements were recorded with three biological replicates.

Reviewer 2 Report

Comments and Suggestions for Authors

The reviewed publication is well-written, clear, and understandable. Its individual stages together form a cohesive whole. My main concern pertains to editorial matters - please revise the manuscript according to the guidelines for the Plants journal (the Materials and Methods section should come after the Discussion). Figures added as supplements should not appear in the main text. Please try to increase the resolution of figures with a large amount of data and text.
