I want to use the primer Fw_ITS1 (5'- AGGAGAAGTCGTAACAAGGT -3') to amplify algae but I don't seem to find the original paper of this primer. I can find it in most articles referred to White et al., 1990 (Amplification and direct sequencing of fungal ribosomal RNA genes for phylogenetics), but I can't find it in this paper. Does anyone have an idea what is the "real"/original paper that developed this primer?
Many thanks in advance.
