Pyrenophora_Combined_LSU_ITS_GAPDH_RPB2

This dataset contains the combined multilocus sequence matrix used for phylogenetic analyses of Pyrenophora isolates associated with cereal crops in Japan. The concatenated alignment includes four gene regions (ITS, LSU, rpb2, and gapdh) from isolates, comprising newly obtained Japanese samples and reference strains from culture collections. The dataset was used to clarify species boundaries within Pyrenophora and to confirm that Japanese isolates previously labeled as P. tritici-repentis belong to P. trichostoma. This combined matrix provides molecular evidence for the diversity and taxonomic distinction of Pyrenophora species occurring in Japan.
