AS far as I know, both ITS1F and ITS1 amplify the ITS1-5.8s-ITS2 region, but from literature so far, I found ITS1 primer is being particularly used for yeasts where as ITS1F is referred specific for fungal species. So I am confused whether to use ITS1F primer or stick to ITS1 primer. Can anyone help me in this regard? Thank you in advance.
