The alignment of the 28S gene of several species of Pezizales allowed to select two pairs of primers able to amplify the internal transcribed spacer region of ribosomal DNA in mycorrhizal fungi, such as truffles. The higher yield of the amplification product demonstrates a better annealing of the new primers to the rDNA, as compared to the universal primers internal transcribed spacer 1 and internal transcribed spacer 4. Therefore, the new primers can be used as an easier and more sensitive tool for the identification of truffle species in any stage of their life cycle, including the mycorrhizal phase.
