Dear authors,
Thank you for your responses to the reviewers' comments. While both reviewers are generally supportive of your work, they also have provided numerous comments and suggestions that need to be addressed. Specifically, the revised manuscript should better justify the choice of species for comparison, discuss the role of variability among strains, and stress the differences and commonalities between the two species under consideration. All tables and figures should indicate clearly whether the material presented refers to Ehux only or to both species.
I invite you now to submit a revised manuscript that should take into account those comments, as outlined in your response. The revised manuscript will be sent for additional review to at least one of the original referees.
Best regards,
Emilio Marañón
