I'm looking for evidence showing that fITS7-ITS4 primers do a better job at capturing more EMF diversity in soil and root samples compared to ITS1f-ITS2 for Illumina seq. Thanks!!
You won't be getting any clear answer to this question and no one can say which primers are better in general. This is a subjective issue and specific for the sample types. This type of comparison would only be valid if sample and both primer sets are put into equation. Theoretically some primer can be better than others but in practice this can be different.
