We have therefore clarified this choice and added this part to the first M&M section and the literature suggested has been cited: “Sequences termed Synechococcus on the other hand were analysed together with sequences of Prochlorococcus, since Synechococcus is known to be a polyphyletic group and if all sequences (including a minimum of five lineages [36–38]) are taken together, Prochlorococcus has to be included too.”
Round 1: and Author Response The authors tested novel approach to identification of species in cyanobacteria based on 16S rRNA based on identification of barcoding gaps previously used in animals.
