I did see that but I noticed all their current publications do not have it italicized. So, I was concerned if I need to change it but I will stick with the guidelines for now. Thank you for your help. I appreciate it.
Huh, I see that. I'd honestly submit as is based on their guidelines. If they ask you to remove the italics, its literally one line in the style (just removing <et-al font-style="italic"/> in the Nature style -- the Communications Biology style is just a link to that), but I'd be surprised if it's something they actually want authors to do.
