I received review comments on a manuscript submitted about 6 months back. One of the reviewers suggested performing a few new experiments. But the same experiments were performed recently and the results have already been communicated elsewhere for possible consideration. How should I address the comment?
I think @EthanBolker's suggestion is spot on: ask the editor. Additionally, if your field is permissive of preprints, you may be able to submit and cite a preprint of the work you've already submitted for review - check the policies of the journal you've already submitted to. Depending on the delays for review on each paper you may be able to update the citation before publishing or it may remain with the preprint, either is fine.
